Properties

	Name	Description
	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.)
	Elements	Gets or sets the elements in the projection list in the order of appearance
	ElementsPerName	Gets or sets the list of elements in the projection list, stored under the name of the element they'll project to
	ElementTypesPerName	Gets or sets the list of the types of the elements in the projection list, stored under the name of teh element they'll project to.
	NodeType	Gets the node type of this Expression. (Inherited from CommonExpression.)
	PreProjectionDataBuckets	Gets or sets the pre projection data buckets of contained entity projections collected by this expression.
	ProjectionInstantiatorLambda	Gets or sets the projection instantiator function lambda. This function is a modified version of the projection lambda
	ProjectorFuncIndexPerElement	Gets or sets the list of flags if an element is a CTor argument or not.
	RelationsToUse	Relations collection for the relations to traverse to be able to fulfill the projection. These relations are from the fields in the projection specification itself.
	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.)
	AddElement(String, Object, Type, Int32, MappingTracker, Boolean)	Adds the specified element to the projectionlist
	AddElement(String, Object, Type, Int32, Boolean, MappingTracker, Boolean)	Adds the specified element to the projectionlist
	AddExpressionElement	Adds the linq expression element to this expression
	AddRelations	Adds the relations.
	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 CommonExpressionHandle(ScopeHandlerBase).)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	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.)
	ToString	Returns a textual representation of the Expression. (Overrides ExpressionToString.)
	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.)
