CorrelationRelationFinderHandleExpression Method

Parameters

expressionToHandle

Type: System.Linq.ExpressionsExpression
The expression to handle.

Return Value

Type: Expression
the result expression after the expression has been handled.

Handling an expression is like Visiting a node in a graph using the visitor pattern. However, as the code in Linq's Expression trees isn't really capable of to be used with visitors (as the expression objects can't call a passed in visitor, as there's no mechanism to do so), the handler is placed outside the expression tree and not really in a visitor pattern way. This routine is the central dispatcher for the expression nodes found in the expression tree.
