Syntax

public sealed class MonadAbstraction : MonadMember

Properties

Inner

The query tree this object wraps.

Declaration

public QueryTree Inner { get; }

Property Value

Type	Description
QueryTree

QueryNodeType

Gets the QueryNodeType of the QueryTree.

Declaration

public override QueryNodeType QueryNodeType { get; }

Property Value

Type	Description
QueryNodeType

Overrides

QueryTree.QueryNodeType

Methods

Accept<TQueryTree, TMonadMember, TQueryOperator>(QueryVisitor<TQueryTree, TMonadMember, TQueryOperator>)

Accepts the query expression tree node in the specified visitor.

Declaration

protected override TQueryTree Accept<TQueryTree, TMonadMember, TQueryOperator>(QueryVisitor<TQueryTree, TMonadMember, TQueryOperator> visitor)
    where TMonadMember : TQueryTree where TQueryOperator : TMonadMember

Parameters

Type	Name	Description
QueryVisitor<TQueryTree, TMonadMember, TQueryOperator>	visitor	Visitor to process the current query expression tree node.

Returns

Type	Description
TQueryTree	Result of visiting the node.

Type Parameters

Name	Description
TQueryTree	Target type for query expressions.
TMonadMember	Target type for monad member query expressions. This type has to derive from TQueryTree.
TQueryOperator	Target type for query operator query expressions. This type has to derive from TMonadMember.

Overrides

System.Linq.CompilerServices.Optimizers.QueryTree.Accept<TQueryTree, TMonadMember, TQueryOperator>(System.Linq.CompilerServices.Optimizers.QueryVisitor<TQueryTree, TMonadMember, TQueryOperator>)

Reduce()

Reduces the current node to an equivalent System.Linq.Expressions.Expression.

Declaration

public override sealed Expression Reduce()

Returns

Type	Description
System.Linq.Expressions.Expression	This node's equivalent System.Linq.Expressions.Expression.

Overrides

QueryTree.Reduce()

Update(QueryTree)

Creates a monad abstraction query expression that is like this one, but using the supplied children. If all of the children are the same, it will return this expression.

Declaration

public MonadAbstraction Update(QueryTree inner)

Parameters

Type	Name	Description
QueryTree	inner	The Inner child node of the result.

Returns

Type	Description
MonadAbstraction	This query expression if no children are changed or an expression with the updated children.
