ExpressionRewriterLeafCollection<TTarget>

Implements

System.Collections.Generic.IEnumerable<Leaf<ExpressionTreeBase, TTarget>>

System.Collections.IEnumerable

Namespace: System.Linq.CompilerServices

Assembly: Nuqleon.Linq.CompilerServices.dll

Syntax

public class ExpressionRewriterLeafCollection<TTarget> : Object, IEnumerable<Leaf<ExpressionTreeBase, TTarget>>, IEnumerable where TTarget : ITree

Type Parameters

Name	Description
TTarget	Type of the target tree nodes.

Methods

Add<TLeaf>(Expression<Func<TLeaf, TTarget>>, Int32)

Adds a new leaf rule.

Declaration

public void Add<TLeaf>(Expression<Func<TLeaf, TTarget>> convert, int cost)
    where TLeaf : Expression

Parameters

Type	Name	Description
System.Linq.Expressions.Expression<System.Func<TLeaf, TTarget>>	convert	Lambda expression representing the conversion from the source tree leaf node to the target tree node.
System.Int32	cost	Cost to apply the rule.

Type Parameters

Name	Description
TLeaf	Type of the source tree leaf node. This type should be a subtype of Expression.

Add<TLeaf>(Expression<Func<TLeaf, TTarget>>, Expression<Func<TLeaf, Boolean>>, Int32)

Adds a new leaf rule.

Declaration

public void Add<TLeaf>(Expression<Func<TLeaf, TTarget>> convert, Expression<Func<TLeaf, bool>> predicate, int cost)
    where TLeaf : Expression

Parameters

Type	Name	Description
System.Linq.Expressions.Expression<System.Func<TLeaf, TTarget>>	convert	Lambda expression representing the conversion from the source tree leaf node to the target tree node.
System.Linq.Expressions.Expression<System.Func<TLeaf, System.Boolean>>	predicate	Lambda expression representing the predicate to apply to evaluate applicability of the rule to a source tree leaf node.
System.Int32	cost	Cost to apply the rule.

Type Parameters

Name	Description
TLeaf	Type of the source tree leaf node. This type should be a subtype of Expression.

GetEnumerator()

Gets an enumerator to iterate over the leaf rules in the collection.

Declaration

public IEnumerator<Leaf<ExpressionTreeBase, TTarget>> GetEnumerator()

Returns

Type	Description
System.Collections.Generic.IEnumerator<Leaf<ExpressionTreeBase, TTarget>>	Enumerator to iterate over the leaf rules in the collection.
