public interface JavaStackFrame

Represents a frame on a Java thread stack.

Method Summary

Modifier and Type	Method	Description
boolean	equals(Object obj)	Compares the argument to the receiver, and answers true if they represent the same object using a class specific comparison.
ImagePointer	getBasePointer()	Get a pointer to the base of this stack frame
Iterator	getHeapRoots()	Get the set of object roots from this stack frame.
JavaLocation	getLocation()	Get the location at which the method owning this frame is currently executing
int	hashCode()	Answers an integer hash code for the receiver.

Method Details

getBasePointer

ImagePointer getBasePointer()
                     throws CorruptDataException

Get a pointer to the base of this stack frame

Returns:

the base pointer of the stack frame

Throws:

CorruptDataException

getLocation

JavaLocation getLocation()
                  throws CorruptDataException

Get the location at which the method owning this frame is currently executing

Returns:

• JavaLocation

getHeapRoots

Iterator getHeapRoots()

Get the set of object roots from this stack frame.

Returns:

an iterator of JavaReferences

equals

boolean equals(Object obj)

Description copied from class: java.lang.Object

Compares the argument to the receiver, and answers true if they represent the same object using a class specific comparison. The implementation in Object answers true only if the argument is the exact same object as the receiver (==).

Overrides:

equals in class Object

Parameters:

obj -

Returns:

True if the given object refers to the same Java Stack Frame in the image

See Also:

• Object.hashCode()

hashCode

int hashCode()

Description copied from class: java.lang.Object

Answers an integer hash code for the receiver. Any two objects which answer true when passed to .equals must answer the same value for this method.

Overrides:

hashCode in class Object

Returns:

the receiver's hash.
