LinqExpressionAsSetExpression Class

Special expression class which is used in expression tree handling to have a LinqExpression be used as a SetExpression. The member is evaluated later on but should be seen as a set, so it can get an alias first.

Copy

public class LinqExpressionAsSetExpression : SetExpression

Public Class LinqExpressionAsSetExpression
	Inherits SetExpression

The LinqExpressionAsSetExpression type exposes the following members.

Properties

	Name	Description
	Alias	Gets or sets the Alias assigned to this set. (Inherited from SetExpression.)
	CanReduce	Indicates that the node can be reduced to a simpler node. If this returns true, Reduce() can be called to produce the reduced form. (Inherited from Expression.)
	ContainedAliases	Gets or sets the AliasContainer which contains the aliases inside this direct set which are reachable only INSIDE this set. If null, it has no aliases directly inside this set, it can be the source might have contained aliases. (Inherited from SetExpression.)
	IsExtractionLocked	Gets or sets a value indicating whether this instance is extraction locked, which means a where/orderby extractor won't touch it. (Inherited from SetExpression.)
	NodeType	Gets the node type of this Expression. (Inherited from CommonExpression.)
	RepresentedExpression	Gets or sets the represented expression
	RequiresProjection	Flag which is set if this set requires a projection to be usable. This flag is later on used to determine if a projection has to be injected into the processing result of this set if there's none defined (true), or not (false). Default is false; (Inherited from SetExpression.)
	Source	Gets or sets the source expression of the select (Inherited from SetExpression.)
	Type	Gets the static type of the expression that this Expression represents. (Inherited from CommonExpression.)

Methods

	Name	Description
	Accept	Dispatches to the specific visit method for this node type. For example, MethodCallExpression calls the VisitMethodCall(MethodCallExpression). (Inherited from Expression.)
	AssignNewAliasIfRequired	Assigns a new alias to this set, if necessary (Inherited from SetExpression.)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Handle	Handles this instance using the specified handler. (Overrides SetExpressionHandle(ScopeHandlerBase).)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	NewAliasAssigned	A new alias was set, using AssignNewAliasIfRequired. Use this method to map a wrapped expression to the alias set in the tracker passed in. (Overrides SetExpressionNewAliasAssigned(MappingTracker).)
	Reduce	Reduces this node to a simpler expression. If CanReduce returns true, this should return a valid expression. This method can return another node which itself must be reduced. (Inherited from Expression.)
	ReduceAndCheck	Reduces this node to a simpler expression. If CanReduce returns true, this should return a valid expression. This method can return another node which itself must be reduced. (Inherited from Expression.)
	ReduceExtensions	Reduces the expression to a known node type (that is not an Extension node) or just returns the expression if it is already a known type. (Inherited from Expression.)
	SetRequiresProjectionFlag	Sets the RequiresProjection flag if this expression isn't an EntityExpression (Inherited from SetExpression.)
	ToString	Returns a textual representation of the Expression. (Inherited from Expression.)
	VisitChildren	Reduces the node and then calls the visitor delegate on the reduced expression. The method throws an exception if the node is not reducible. (Inherited from Expression.)
