IDebugExpressionContext2

This interface represents a context for expression evaluation.

Syntax

IDebugExpressionContext2 : IUnknown

Notes for Implementers

The debug engine (DE) implements this interface to represent a context in which an expression can be evaluated.

Notes for Callers

A call to GetExpressionContext returns the this interface. This interface is accessible only when the program being debugged has been paused and a stack frame is available.

Methods in Vtable Order

The following table shows the methods of IDebugExpressionContext2.

Method Description
GetName Retrieves the name of the evaluation context.
ParseText Parses a text-based expression for evaluation.

Remarks

An evaluation context can be thought of as a scope for performing expression evaluation.

When a program has halted, the session debug manager (SDM) obtains a stack frame from the DE with a call to EnumFrameInfo. The SDM then calls GetExpressionContext to get the IDebugExpressionContext2 interface. This is followed by a call to ParseText to create an IDebugExpression2 interface, which represents the parsed expression ready to be evaluated.
