Important
In Visual Studio 2015, this way of implementing expression evaluators is deprecated. For information about implementing CLR expression evaluators, please see CLR Expression Evaluators and Managed Expression Evaluator Sample.
This interface represents a parsed expression ready to be evaluated.
Syntax
IDebugParsedExpression : IUnknown
Notes for Implementers
An expression evaluator implements this interface to represent a parsed expression that is ready for evaluation.
Notes for Callers
A call to Parse returns this interface.
Methods in Vtable Order
The following table shows the method of IDebugParsedExpression.
| Method | Description |
|---|---|
| EvaluateSync | Evaluates the parsed expression. |
Remarks
When the caller is ready to evaluate the expression, it calls EvaluateSync to return an IDebugProperty2 that contains the result of the evaluation. This two-part approach to evaluation, parsing then evaluating, enables the parsed expression to be evaluated multiple times, bypassing the time-consuming process of parsing the expression.
