Method Detail

computePresentation

public abstract void computePresentation(XValueNode node,
                                         XValuePlace place)

Start computing presentation of the value in the debugger tree and call XValueNode.setPresentation(javax.swing.Icon, String, String, boolean) when computation is finished. Note that this method is called from the Event Dispatch thread so it should return quickly.

Parameters:

node - node

place - where the node will be shown.

getEvaluationExpression

public java.lang.String getEvaluationExpression()

Returns:

expression which evaluates to the current value

calculateEvaluationExpression

public Promise<XExpression> calculateEvaluationExpression()

Asynchronously calculates expression which evaluates to the current value

getInstanceEvaluator

public XInstanceEvaluator getInstanceEvaluator()

Returns:

evaluator to calculate value of the current object instance

getModifier

public XValueModifier getModifier()

Returns:

XValueModifier instance which can be used to modify the value

computeSourcePosition

public void computeSourcePosition(XNavigatable navigatable)

Start computing source position of the value and call XNavigatable.setSourcePosition(com.intellij.xdebugger.XSourcePosition) when computation is finished. Note that this method is called from the Event Dispatch thread so it should return quickly.

Parameters:

navigatable - navigatable

computeInlineDebuggerData

public ThreeState computeInlineDebuggerData(XInlineDebuggerDataCallback callback)

Provide inline debugger data, return ability to provide, use ThreeState.UNSURE if unsupported (default platform implementation will be used), ThreeState.YES if applicable ThreeState.NO if not applicable

canNavigateToSource

public boolean canNavigateToSource()

Return true from this method and override computeSourcePosition(XNavigatable) if navigation to the source is supported for the value

Returns:

true if navigation to the value's source is supported

canNavigateToTypeSource

public boolean canNavigateToTypeSource()

Return true from this method and override computeTypeSourcePosition(XNavigatable) if navigation to the value's type is supported for the value

Returns:

true if navigation to the value's type is supported

computeTypeSourcePosition

public void computeTypeSourcePosition(XNavigatable navigatable)

Start computing source position of the value's type and call XNavigatable.setSourcePosition(com.intellij.xdebugger.XSourcePosition) when computation is finished. Note that this method is called from the Event Dispatch thread so it should return quickly.

getReferrersProvider

public XReferrersProvider getReferrersProvider()

This enables showing referrers for the value

Returns:

provider that creates an XValue returning objects that refer to the current value or null if showing referrers for the value is disabled
