Methods

	Name	Description
	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.)
	FindFunctionMapping(MemberInfo)	Finds the function mapping associated with the property specified.
	FindFunctionMapping(MethodInfo)	Finds the function mapping associated with the method/function specified.
	FindFunctionMapping(String, Type, Int32)	Finds the function mapping associated with the method/function specified.
	FindGroupJoinExpressionAsCopy	Finds the group join expression using the alias of the right side. It then creates a copy of it (and its contents) so the caller can manipulate it.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)

	HandleBinaryExpressionBooleanOperator	Handles the binary expression with a boolean operator.
	HandleConditionalExpression	Handles the conditional expression.
	HandleConstantExpression	Handles the constant expression.
	HandleContainsExpression	Handles the contains expression.
	HandleDbFunctionCallExpression	Handles the db function call expression.

	HandleElementInitializerList	Handles the element initializer list.
	HandleEntityExpression	Handles the entity expression.
	HandleEntityFieldExpression	Handles the entity field expression.
	HandleExceptIntersectExpression	Handles the except expression.
	HandleExcludeIncludeFieldsExpression	Handles the exclude include fields expression.
	HandleExpression	Handles the expression.
	HandleExpressionList	Handles the expression list.

	HandleGroupByExpression	Handles the group by expression.
	HandleGroupByKeyReferenceExpression	Handles the group by key reference expression.
	HandleGroupJoinExpression	Handles the groupjoin expression.
	HandleInClauseExpression	Handles the in clause expression, which is an expression representing a call to Contains on a list of values.
	HandleInMemoryEvalCandidateExpression	Handles the in memory eval candidate expression.
	HandleInvocationExpression	Handles the invocation expression.
	HandleJoinExpression	Handles the join expression.
	HandleJoinResultExpression	Handles the JoinResult expression.
	HandleLambdaExpression	Handles the lambda expression.
	HandleLikeExpression	Handles the like expression.
	HandleLinqExpressionAsSetExpression	Handles the LinqExpression as set expression.
	HandleListInitExpression	Handles the list init expression.
	HandleLLBLGenProExpressionExpression	Handles the LLBLGenProExpressionExpression.
	HandleMemberAssignment	Handles the member assignment.

	HandleUnaryConvertExpression	Handles the unary convert expression.
	HandleUnaryExpression	Handles the unary expression.
	HandleUnaryNotExpression	Handles the unary expression of type 'Not'.
	HandleUnaryTypeAsExpression	Handles the unary type as expression.
	HandleUnionList	Handles the specified unionlist and its contained set expressions. Will return a new list if one or more set expressions changed after handling.
	HandleWhereExpression	Handles the where expression.
