Modifier and TypeMethod and Description
public boolean
canMaterializeVirtualObjects()

Overrides default jdk.vm.ci.code.stack.StackIntrospection.canMaterializeVirtualObjects.

Determines if InspectedFrame#materializeVirtualObjects(boolean) can be called for frames visited by iterateFrames.

public <T> T
iterateFrames(ResolvedJavaMethod[]
if this is non-null, then the stack walk will start at the first frame whose method is one of these methods.
initialMethods, ResolvedJavaMethod[]
if this is non-null, then only frames whose methods are in this array are visited
matchingMethods, int
the number of matching methods to skip (including the initial method)
initialSkip, InspectedFrameVisitor<T>
the visitor that is called for every matching method
visitor)

Implements jdk.vm.ci.code.stack.StackIntrospection.iterateFrames.

Walks the current stack, providing InspectedFrames to the visitor that can be used to inspect the stack frame's contents.

public <T> T iterateFrames(ResolvedJavaMethod[] initialMethods, ResolvedJavaMethod[] matchingMethods, int initialSkip, InspectedFrameVisitor<T> visitor)

Implements jdk.vm.ci.code.stack.StackIntrospection.iterateFrames.

Doc from jdk.vm.ci.code.stack.StackIntrospection.iterateFrames.

Walks the current stack, providing InspectedFrames to the visitor that can be used to inspect the stack frame's contents. Iteration continues as long as InspectedFrameVisitor#visitFrame, which is invoked for every InspectedFrame, returns null. A non-null return value from InspectedFrameVisitor#visitFrame indicates that frame iteration should stop.

Parameters
initialMethods:ResolvedJavaMethod[]

if this is non-null, then the stack walk will start at the first frame whose method is one of these methods.

matchingMethods:ResolvedJavaMethod[]

if this is non-null, then only frames whose methods are in this array are visited

initialSkip:int

the number of matching methods to skip (including the initial method)

visitor:InspectedFrameVisitor<T>

the visitor that is called for every matching method

Returns:T

the last result returned by the visitor (which is non-null to indicate that iteration should stop), or null if the whole stack was iterated.
