Properties
| EvaluationResult |
The result of evaluating this visualized child. The expression evaluator reserves the right to override this instance so do not rely on storing data items in the DkmEvaluationResult instance. Use the DkmVisualizedExpression instance as a data container instead. |
| Index |
The index of this child in the parent object's child collection. The expression evaluator will use this when processing the full name of a child item. The full name is used when the user clicks on an item and says Add To Watch or when the user types something in the watch window directly. If the visualizer does not provide a full name, then callback to the expression evaluator to construct a default expand expression The value of the index field will be used to obtain the correct expand expression. |
| InspectionContext |
Options and target context to use while performing the inspection operation. (Inherited from DkmVisualizedExpression) |
| InspectionSession |
The InspectionSession allows the various components which examine data in the target process to store private data with the same lifetime. Inspection sessions are closed when the user attempts to continue the process. (Inherited from DkmVisualizedExpression) |
| IsUnloaded |
Returns true if a 'unloaded' event has been raised for this object (example: DkmThread::Unload is called) or if the object has been closed. Note that care must be used when checking this status as, without synchronization, the returned status may no longer be accurate the instruction after it is read. (Inherited from DkmDataContainer) |
| Parent |
The Parent of this visualized child. |
| RuntimeInstance |
Indicates which runtime monitor will be used to perform this evaluation. (Inherited from DkmVisualizedExpression) |
| SourceId |
Guid which ties together the expression evaluator that created this object and the object itself. Generally used by expression evaluators to filter their implementation of IDkmCustomVisualizerCallback to only DkmVisualizedExpression they created. (Inherited from DkmVisualizedExpression) |
| StackFrame |
Stack frame the expression is being evaluated in expression in. (Inherited from DkmVisualizedExpression) |
| TagValue |
DkmVisualizedExpression is an abstract base class. This enum indicates which derived class this object is an instance of. (Inherited from DkmVisualizedExpression) |
| UniqueId |
Guid which uniquely identifies this instance. (Inherited from DkmVisualizedExpression) |
| ValueHome |
[Optional] The location at which the value is stored, which can be modified to edit the value. This should be null for read-only values, such as integer constants. (Inherited from DkmVisualizedExpression) |
| VisualizerId |
Guid which ties together the addin and the expressions that call that addin. The addin should use the Guid provided in the native visualizer file as a filter. (Inherited from DkmVisualizedExpression) |
Methods
| Close() |
Closes a DkmVisualizedExpression object instance. This will release any resources associated with this object across all components. This includes resources across computer or managed/native marshalling boundaries. DkmVisualizedExpression objects are automatically closed when their associated DkmInspectionSession object is closed. (Inherited from DkmVisualizedExpression) |
| Create(DkmInspectionContext, Guid, Guid, DkmStackWalkFrame, DkmExpressionValueHome, DkmEvaluationResult, DkmVisualizedExpression, UInt32, DkmDataItem) |
Create a new DkmChildVisualizedExpression object instance. |
| CreateDefaultChildFullName(Int32) |
This method will construct a default full name for a custom visualized child expression. This name will be the root expression's full name and an expand format string that will cause the expression evaluator to callback to the visualizer to obtain children. The DkmVisualizedExpression instance this is called on should be the parent visualized expression for a child and the root visualized expression for a root. (Inherited from DkmVisualizedExpression) |
| EvaluateExpressionCallback(DkmInspectionContext, DkmLanguageExpression, DkmStackWalkFrame, DkmEvaluationResult) |
This method allows a visualizer addin use the expression evaluator to compile and evaluate the default value for an expression. The addin can use this result as-is or override fields by creating a new result. The addin can also choose to use the expression evaluator for expansion using the the get children callbacks. (Inherited from DkmVisualizedExpression) |
| EvaluateVisualizedExpression(DkmEvaluationResult) |
Evaluate a visualized expression returning a DkmEvaluationResult for it. Location constraint: API must be called from an IDE component (component level > 100,000). (Inherited from DkmVisualizedExpression) |
| GetChildren(Int32, DkmInspectionContext, DkmChildVisualizedExpression[], DkmEvaluationResultEnumContext) |
Gets an enumeration context used to obtain the children of this evaluation result. This is used in all expression evaluation windows. Location constraint: API must be called from an IDE component (component level > 100,000). (Inherited from DkmVisualizedExpression) |
| GetChildrenCallback(DkmEvaluationResult, Int32, DkmInspectionContext, DkmEvaluationResult[], DkmEvaluationResultEnumContext) |
This method allows a visualizer addin use the expression evaluator for expansion. The evaluation result contained within the visualized expression must have come from the expression evaluator via EvaluateExpressionCallback. (Inherited from DkmVisualizedExpression) |
| GetDataItem<T>() |
Gets the instance of 'T' which has been added to this container instance. If this container does not contain a 'T', this function will return null. (Inherited from DkmDataContainer) |
| GetItems(DkmEvaluationResultEnumContext, Int32, Int32, DkmChildVisualizedExpression[]) |
Called to obtain items from a instance of DkmEvaluationResultEnumContext created by an earlier call to GetChildren. Location constraint: API must be called from an IDE component (component level > 100,000). (Inherited from DkmVisualizedExpression) |
| GetItemsCallback(DkmEvaluationResultEnumContext, Int32, Int32, DkmEvaluationResult[]) |
This method allows a visualizer addin use the expression evaluator for expansion using the passed enumeration context. This is used to obtain local variables of a stack frame or child members from an evaluation result. (Inherited from DkmVisualizedExpression) |
| GetSymbolInterface(Guid, Object) |
Allows custom expression evaluator addins to obtain the symbol interface for the type being visualized. This is not stored in the DkmVisualizedExpression directly to enable addins that live on the remote machine and do not depend on symbols. Location constraint: API must be called from an IDE component (component level > 100,000). (Inherited from DkmVisualizedExpression) |
| GetUnderlyingString() |
This method is used for evaluation results that include DkmEvaluationResultFlags.RawString to obtain the the underlying string, with no enclosing quotes or escape sequences. This is method is invoked to display one of the various string visualizers in an expression evaluation window (click the magnifying glass icon). Location constraint: API must be called from an IDE component (component level > 100,000). (Inherited from DkmVisualizedExpression) |
| GetUnderlyingStringCallback(DkmEvaluationResult) |
This method is used for evaluation results that include DkmEvaluationResultFlags.RawString to obtain the the underlying string, with no enclosing quotes or escape sequences. This is method is invoked to display one of the various string visualizers in an expression evaluation window (click the magnifying glass icon). (Inherited from DkmVisualizedExpression) |
| RemoveDataItem<T>() |
Remove the instance of 'T' from this container. It is usually unnecessary to call this method as a data container will automatically be emptied when the object is closed. (Inherited from DkmDataContainer) |
| SetDataItem<T>(DkmDataCreationDisposition, T) |
Place a new item in the data container. (Inherited from DkmDataContainer) |
| SetValueAsString(String, Int32, String) |
Modifies the value of the given evaluation result (assumed to be non-read-only) to match the given string. This is used after the user edits a value in any of the evaluation windows. Location constraint: API must be called from an IDE component (component level > 100,000). (Inherited from DkmVisualizedExpression) |
| SetValueAsStringCallback(DkmEvaluationResult, String, Int32, String) |
Modifies the value of the given evaluation result (assumed to be non-read-only) to match the given string. This is used after the user edits a value in any of the evaluation windows. (Inherited from DkmVisualizedExpression) |
| UseDefaultEvaluationBehavior(Boolean, DkmEvaluationResult) |
Called by the expression evaluator when a visualized expression's children are being expanded, the the value is being set, or the underlying string is being obtained. If the visualizer addin wants complete control of the expression it should return false. It will then receive calls to GetChildren, GetItems, SetValueAsString, and GetUnderlyingString. If the visualizer addin wants to completely defer these operations to the expression evaluator, it should return true. It must also give the expression evaluator back the instance of DkmEvaluationResult that came from the EE via one of the IDkmCustomVisualizerCallback methods. Note that the addin MUST have obtained the default DkmEvaluationResult from the EE if it wants the EE to control the object. Returning true from this method is primarily used by visualizer addins that just tweak something small like the view of a value but don't want to modify expansion or setting values. Location constraint: API must be called from an IDE component (component level > 100,000). (Inherited from DkmVisualizedExpression) |
