This document explains how queries are generated from filter objects using the `ApplyFilter()` method as the entry point. + +## Architecture Overview + +The query generation in AutoFilterer follows a **layered architecture** with distinct responsibilities: + +1. **Entry Point Layer** - `QueryExtensions.ApplyFilter()` +2. **Filter Processing Layer** - `IFilter` interface and `FilterBase` class +3. **Expression Building Layer** - Attribute-based expression builders +4. **Ordering & Pagination Layer** - `IOrderable` and `IPaginationFilter` interfaces +5. **LINQ Execution Layer** - Final query execution + +## 1. Entry Point: QueryExtensions.ApplyFilter() + +### Location +[Extensions/QueryExtensions.cs](src/AutoFilterer/Extensions/QueryExtensions.cs) + +### Purpose +The `ApplyFilter()` method serves as the public API gateway for applying filters to LINQ queries. + +### Overloads + +```csharp +// Works with unordered IQueryable +public static IQueryable ApplyFilter(this IQueryable source, IFilter filter) +{ + return filter.ApplyFilterTo(source); +} + +// Works with already ordered IOrderedQueryable +public static IQueryable ApplyFilter(this IOrderedQueryable source, IFilter filter) +{ + return filter.ApplyFilterTo(source); +} +``` + +### Key Characteristics +- **Generic Method**: Works with any entity type `T` +- **Extension Method**: Seamlessly integrates with LINQ query chains +- **Chainable**: Allows combining with other LINQ operations +- **Delegation Pattern**: Delegates actual filter logic to the filter object's `ApplyFilterTo()` method + +### Example Usage + +```csharp +// Basic filtering +var books = db.Books + .ApplyFilter(filter) + .ToList(); + +// With additional Where clauses +var books = db.Books + .Where(x => !x.IsDeleted) + .ApplyFilter(filter) + .Select(s => s.Name) + .ToList(); +``` + +## 2. Filter Processing Layer + +### IFilter Interface + +```csharp +public interface IFilter +{ + Expression BuildExpression(Type entityType, Expression body); + IQueryable ApplyFilterTo(IQueryable query); +} +``` + +### Core Components + +#### FilterBase Class +The base class for all filter implementations. It contains the core logic for: +1. **Expression Building** - Creating LINQ expressions from filter properties +2. **Query Transformation** - Converting expressions into WHERE clauses +3. **Property Reflection** - Scanning filter object for filterable properties + +### Query Generation Flow + +``` +ApplyFilter() + ↓ +IFilter.ApplyFilterTo() + ↓ +FilterBase.ApplyFilterTo() + ├─ Create parameter expression: Expression.Parameter(typeof(T), "x") + ├─ Build filter expression via BuildExpression() + ├─ Create lambda: Expression.Lambda>(exp, parameter) + └─ Apply WHERE: query.Where(lambda) +``` + +## 3. Expression Building Layer + +### 3.1 BuildExpression Method + +The heart of the filter system. This method: + +1. **Iterates** through all properties of the filter object +2. **Reflects** on property types and attributes +3. **Builds** individual filter expressions for each property +4. **Combines** expressions using AND/OR logic + +### Detailed Flow + +``` +FilterBase.BuildExpression(Type entityType, Expression body) + ↓ +For each property in filter class: + ├─ Get property value + ├─ Skip null values and properties with [IgnoreFilter] + ├─ Get [CompareTo] or [FilteringOptions] attributes + ├─ For each attribute: + │ └─ BuildExpressionForProperty() → Creates expression + └─ Combine expressions with CombineType (AND/OR) +``` + +### ExpressionBuildContext + +The context object that carries all necessary information for building an expression: + +```csharp +public class ExpressionBuildContext +{ + public Expression ExpressionBody { get; } // Current expression body (e.g., "x") + public PropertyInfo TargetProperty { get; } // Property on entity being filtered + public PropertyInfo FilterProperty { get; } // Property on filter object + public Expression FilterPropertyExpression { get; } // Expression for filter value + public IFilter FilterObject { get; } // The filter object instance + public object FilterObjectPropertyValue { get; } // Actual value of filter property +} +``` + +## 4.

Eq { get; set; } // Equal + public T? Not { get; set; } // Not equal + public T? Gt { get; set; } // Greater than + public T? Lt { get; set; } // Less than + public T? Gte { get; set; } // Greater than or equal + public T? Lte { get; set; } // Less than or equal + public bool? IsNull { get; set; } + public bool? IsNotNull { get; set; } +} +``` + +### Range Type + +For filtering numeric ranges: + +```csharp +public class Range : IRange +{ + public T? Start { get; set; } + public T? End { get; set; } +} +``` + +**Filter Expression**: +``` +property >= Start AND property <= End +``` + +## 6. Expression Combination + +### CombineType Enum + +Determines how multiple conditions are joined: + +```csharp +public enum CombineType +{ + And, // && operator + Or // || operator +} +``` + +### ExpressionExtensions.Combine() + +Intelligently combines expressions: + +```csharp +public static Expression Combine(this Expression left, Expression right, CombineType combineType) +{ + if (left == null) return right; + if (right == null) return left; + + // Skip parameter and member expressions + if (left is ParameterExpression || left is MemberExpression) return right; + if (right is ParameterExpression || right is MemberExpression) return left; + + // Combine with AND or OR + if (combineType == CombineType.And) + return Expression.AndAlso(left, right); + else + return Expression.OrElse(left, right); +} +``` + +### Example Expression Combination + +```csharp +// Filter: Name = "John" OR Name = "Jane" +Expression 1: x => x.Name == "John" +Expression 2: x => x.Name == "Jane" +Combine(Expr1, Expr2, Or) → x => (x.Name == "John") || (x.Name == "Jane") + +// Filter: Age > 18 AND Status = Active +Expression 1: x => x.Age > 18 +Expression 2: x => x.Status == Active +Combine(Expr1, Expr2, And) → x => (x.Age > 18) && (x.Status == Active) +``` + +## 7. Ordering Layer + +### IOrderable Interface + +```csharp +public interface IOrderable +{ + Sorting SortBy { get; set; } // Ascending or Descending + string Sort { get; } // Property name to sort by + IOrderedQueryable ApplyOrder(IQueryable source); +} +``` + +### OrderableBase Implementation + +``` +ApplyOrder() method: + ├─ Validate Sort property name is not empty + ├─ Create parameter expression for entity + ├─ Build member expression from property name (supports nested: "Author.Name") + ├─ Create property lambda + ├─ Check [PossibleSortings] attribute for allowed properties + └─ Apply OrderBy or OrderByDescending via reflection +``` + +### Sorting Enum + +```csharp +public enum Sorting +{ + Ascending, + Descending +} +``` + +### Expression Generation for Ordering + +```csharp +// For Ascending order +var lambda = Expression.Lambda(property, parameter); // x => x.PropertyName +orderBy.MakeGenericMethod(typeof(TEntity), propertyType) + .Invoke(null, new[] { source, lambda }); + +// For Descending order +var lambda = Expression.Lambda(property, parameter); +orderByDescending.MakeGenericMethod(typeof(TEntity), propertyType) + .Invoke(null, new[] { source, lambda }); +``` + +## 8. Pagination Layer + +### IPaginationFilter Interface + +```csharp +public interface IPaginationFilter : IFilter +{ + int Page { get; set; } // 1-based page number + int PerPage { get; set; } // Items per page + IQueryable ApplyFilterWithoutPagination(IQueryable query); +} +``` + +### PaginationFilterBase Implementation + +``` +ApplyFilterTo(): + ├─ Check if query is already ordered + ├─ If yes: Apply filters → Apply ordering → Apply pagination + └─ If no: Apply filters → Apply pagination + +ApplyFilterWithoutPagination(): + └─ Applies only WHERE conditions (no Skip/Take) +``` + +### Pagination Logic + +```csharp +public IQueryable ToPaged(this IQueryable source, int page, int pageSize) +{ + // Skip: (page - 1) * pageSize + // Take: pageSize + return source.Skip((page - 1) * pageSize).Take(pageSize); +} +``` + +**Example**: +``` +Page 1, PerPage 10: Skip(0).Take(10) → Items 1-10 +Page 2, PerPage 10: Skip(10).Take(10) → Items 11-20 +Page 3, PerPage 10: Skip(20).Take(10) → Items 21-30 +``` + +## 9.

Key Design Patterns + +### 1. **Visitor Pattern** +The filter object visits each property, determines its type, and builds corresponding expressions. + +### 2. **Strategy Pattern** +Different attributes implement different filtering strategies (string matching, numeric comparison, collection filtering). + +### 3. **Expression Trees** +LINQ Expression Trees allow compile-time query building that translates to efficient SQL. + +### 4. **Template Method Pattern** +`FilterBase.ApplyFilterTo()` defines the structure; `BuildExpression()` is overridden by subclasses. + +### 5. **Decorator Pattern** +`OrderableFilterBase` and `PaginationFilterBase` decorate `FilterBase` to add ordering and pagination. + +### 6. **Reflection** +Properties are discovered at runtime using reflection, allowing automatic binding of filter properties to entity properties. + +## 12. Error Handling and Validation + +### Exception Handling + +By default, exceptions during filter building are suppressed: + +```csharp +public static bool IgnoreExceptions { get; set; } = true; +``` + +Can be set to `false` to debug filter issues. + +### Validation Points + +1. **Null Checks**: Null property values are skipped +2. **Property Existence**: Non-existent entity properties are skipped gracefully +3. **Sorting Validation**: `[PossibleSortings]` attribute restricts allowed sort fields +4. **Pagination Validation**: Page and PageSize must be positive integers + +## 13. Performance Considerations + +### Expression Caching + +- **Formatter Cache**: String format expressions are cached in `ConcurrentDictionary` +- **Expression Compilation**: Lambda expressions are compiled once and reused + +### Lazy Evaluation + +- Expressions are built but not executed until `.ToList()`, `.FirstOrDefault()`, etc. +- This allows the database to handle filtering, not application memory + +### Reflection Overhead + +- Property reflection happens at filter application time +- For high-performance scenarios, consider caching filter schema + +## 14. Extension Points + +### Custom IFilterableType Implementation + +```csharp +public class CustomRangeFilter : IFilterableType +{ + public DateTime? StartDate { get; set; } + public DateTime? EndDate { get; set; } + + public Expression BuildExpression(ExpressionBuildContext context) + { + Expression expression = null; + + if (StartDate.HasValue) + expression = Expression.GreaterThanOrEqual( + Expression.Property(context.ExpressionBody, context.TargetProperty.Name), + Expression.Constant(StartDate.Value) + ); + + if (EndDate.HasValue) + { + var endExpression = Expression.LessThanOrEqual( + Expression.Property(context.ExpressionBody, context.TargetProperty.Name), + Expression.Constant(EndDate.Value) + ); + expression = expression?.Combine(endExpression, CombineType.And) ?? endExpression; + } + + return expression; + } +} +``` + +## 15. Summary + +The AutoFilterer query generation flow is an elegant system that: + +1. **Takes filter objects** as declarative specifications +2. **Uses reflection and attributes** to discover filter requirements +3. **Builds LINQ expressions** that represent WHERE, ORDER BY, and pagination clauses +4. **Combines expressions** intelligently with AND/OR logic +5. **Delegates to LINQ** for final query execution and database translation + +This architecture provides a **type-safe, maintainable, and flexible** approach to building complex queries while keeping business logic separated from query construction. diff --git a/docs/en/generators/SourceGenerator-ApplyFilter.md b/docs/en/generators/SourceGenerator-ApplyFilter.md new file mode 100644 index 0000000..0aa672a --- /dev/null +++ b/docs/en/generators/SourceGenerator-ApplyFilter.md @@ -0,0 +1,423 @@ +# AutoFilterer Source Generator + +## Overview + +The `ApplyFilterGenerator` is an incremental Roslyn source generator that eliminates runtime reflection overhead by generating `ApplyFilter` extension methods at compile time.

Changes to ApplyFilterGenerator introduce a Batch-1 safe generation path, parity prefilters, null-guard builders, single-target resolution helpers, and safer handling for Sort/SortBy and pagination properties. FilterGenerator now parses new GenerateAutoFilterAttribute options (BaseClass, UseStringFilter, UseRangeForNumbers/Dates, GenerateForEnumProperties), adds property-skipping heuristics, and emits DTOs accordingly. TypeMapping entries adjusted for bool/Guid/DateTimeOffset and other fixes. StringFilter and StringFilterOptions updated to reuse a local source expression and wrap comparisons with GuardTargetNotNull to avoid null-reference issues. A large set of generator tests and parity baseline tests were added/updated to cover the new behaviors. --- .../ApplyFilterGenerator.cs | 467 ++++- .../FilterGenerator.cs | 203 +- .../GenerateAutoFilterAttribute.cs | 14 +- src/AutoFilterer.Generators/TypeMapping.cs | 14 +- .../StringFilterOptionsAttribute.cs | 6 +- src/AutoFilterer/Types/StringFilter.cs | 75 +- .../Environment/Dtos/TestFilters.cs | 726 ++++++- .../Environment/Models/TestModels.cs | 73 +- .../FilterGeneratorTests.cs | 361 +++- .../GeneratorParityBaselineTests.cs | 479 +++++ .../GeneratorParityFinalBacklogTests.cs | 1683 +++++++++++++++ .../GeneratorParityNextWaveTests.cs | 438 ++++ .../GeneratorParityP1MatrixTests.cs | 870 ++++++++ .../GeneratorParityP2RecursiveMixedTests.cs | 1840 +++++++++++++++++ .../GeneratorSmokeTests.cs | 255 +++ .../TestDataHelper.cs | 66 +- 16 files changed, 7423 insertions(+), 147 deletions(-) create mode 100644 tests/AutoFilterer.Generators.Tests/GeneratorParityBaselineTests.cs create mode 100644 tests/AutoFilterer.Generators.Tests/GeneratorParityFinalBacklogTests.cs create mode 100644 tests/AutoFilterer.Generators.Tests/GeneratorParityNextWaveTests.cs create mode 100644 tests/AutoFilterer.Generators.Tests/GeneratorParityP1MatrixTests.cs create mode 100644 tests/AutoFilterer.Generators.Tests/GeneratorParityP2RecursiveMixedTests.cs diff --git a/src/AutoFilterer.Generators/ApplyFilterGenerator.cs b/src/AutoFilterer.Generators/ApplyFilterGenerator.cs index 3edf927..97d4577 100644 --- a/src/AutoFilterer.Generators/ApplyFilterGenerator.cs +++ b/src/AutoFilterer.Generators/ApplyFilterGenerator.cs @@ -113,6 +113,9 @@ private static string BuildApplyExtensionSource(string @namespace, INamedTypeSym sb.AppendLine("using AutoFilterer;");

improve generator logic Add AGENTS.md with guidance for autonomous coding agents and repository conventions. Refactor ApplyFilterGenerator: replace the old Batch1 safe gate with a BuildFilterState-driven approach that emits a generated Where condition when applicable; add extensive helper routines (BuildPropertyState/BuildTargetState/BuildCollectionState/BuildNestedFilterState, string/operator/range handling, path guards, CombineStates, etc.). Emit ordering and pagination logic and generate nested filter helpers (HasFilters/ApplyGenerated helpers) to support collection and nested filter scenarios. Update GeneratorAotPathTests to include Level1Filter_AllAnyAnyAnyAnyAnyAny. --- .../ApplyFilterGenerator.cs | 777 +++++++++++++++++- .../GeneratorAotPathTests.cs | 1 + 2 files changed, 766 insertions(+), 12 deletions(-) diff --git a/src/AutoFilterer.Generators/ApplyFilterGenerator.cs b/src/AutoFilterer.Generators/ApplyFilterGenerator.cs index 388af4b..854682f 100644 --- a/src/AutoFilterer.Generators/ApplyFilterGenerator.cs +++ b/src/AutoFilterer.Generators/ApplyFilterGenerator.cs @@ -127,23 +127,17 @@ private static string BuildApplyExtensionSource(string @namespace, INamedTypeSym EmitParityPrefilters(sb, filterSymbol, entitySymbol); - // Batch 1 strict support gate: only use generated path for safe subset - var isBatch1Safe = IsBatch1SafeFilter(filterSymbol, entitySymbol); - if (isBatch1Safe) + var filterState = BuildFilterState(filterSymbol, entitySymbol, "x", "filter"); + if (!string.IsNullOrWhiteSpace(filterState.Condition) && filterState.Condition != "true") { - // Emit generated WHERE conditions - sb.AppendLine(" // Generated WHERE path (Batch 1 safe subset)"); - EmitBatch1WhereConditions(sb, filterSymbol, entitySymbol); - } - else - { - // Fallback to runtime path for unsupported patterns - sb.AppendLine(" // Fallback to runtime path (unsupported for generated mode)"); - sb.AppendLine(" return filter.ApplyFilterTo(source);"); + sb.AppendLine($" source = source.Where(x => {filterState.Condition});"); } + EmitOrderingAndPagination(sb, filterSymbol, entitySymbol); + sb.AppendLine(" return source;"); sb.AppendLine(" }"); + EmitNestedFilterHelpers(sb, filterSymbol, entitySymbol, new HashSet(StringComparer.Ordinal)); sb.AppendLine(" }"); sb.AppendLine("}"); return sb.ToString(); @@ -359,6 +353,765 @@ private static void EmitBatch1WhereConditions(StringBuilder sb, INamedTypeSymbol } } + private static (string Active, string Condition) BuildFilterState(INamedTypeSymbol filterSymbol, INamedTypeSymbol entitySymbol, string paramName, string filterPath) + { + var propertyStates = new List<(string Active, string Expression)>(); + + foreach (var filterProp in filterSymbol.GetMembers().OfType().Where(p => !p.IsStatic && !p.IsIndexer)) + { + var state = BuildPropertyState(filterProp, entitySymbol, paramName, filterPath); + if (!string.IsNullOrWhiteSpace(state.Active) && !string.IsNullOrWhiteSpace(state.Condition)) + { + propertyStates.Add((state.Active, state.Condition)); + } + } + + if (propertyStates.Count == 0) + { + return ("false", "true"); + } + + var anyActive = BuildAnyActiveExpression(propertyStates); + var andExpression = BuildAndExpression(propertyStates); + var orExpression = BuildOrExpression(propertyStates); + + return (anyActive, $"!({anyActive}) || ({filterPath}.CombineWith == CombineType.Or ?
