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 binds a symbol field, typically returned by the symbol provider, to a memory context or object that contains the symbol's current value.

Syntax

IDebugBinder : IUnknown

Notes for Implementers

This interface supports expression evaluation and must be implemented by the debug engine (DE).

Notes for Callers

This interface is used in the process of expression evaluation and is typically used in the implementation of EvaluateSync and EvaluateAsync.

Methods in Vtable Order

The following table shows the methods of IDebugBinder.

Method	Description
Bind	Gets the memory context or object that contains the symbol's current value.
ResolveRuntimeType	Determines the run-time type of an object.
GetMemoryContext	Converts an object location or memory address to a memory context.
GetFunctionObject	Gets an IDebugFunctionObject object used to create function parameters.
ResolveDynamicType	Gets the exact type for a variable.

Remarks

This interface returns objects that are used by the expression evaluator in parse trees. The expression evaluator parses an expression by using the symbol provider to convert the symbols in the expression to instances of IDebugField, which describe each symbol in terms of its type and location in the source code. The Bind method converts IDebugField objects to IDebugObject objects that connect or bind a symbol type to an actual value in memory. These IDebugObject objects are then stored in a parse tree for later evaluation.
