Method Details

getBasePointer

public ImagePointer getBasePointer()
                            throws CorruptDataException

Description copied from interface: JavaStackFrame

Get a pointer to the base of this stack frame

Specified by:

getBasePointer in interface JavaStackFrame

Returns:

the base pointer of the stack frame

Throws:

CorruptDataException

getLocation

public JavaLocation getLocation()
                         throws CorruptDataException

createObjectRef

public void createObjectRef(long id)

equals

public 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 (==).

Specified by:

equals in interface JavaStackFrame

Overrides:

equals in class Object

Parameters:

obj - Object the object to compare with this object.

Returns:

boolean true if the object is the same as this object false if it is different from this object.

See Also:

• Object.hashCode()

hashCode

public 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.

Specified by:

hashCode in interface JavaStackFrame

Overrides:

hashCode in class Object

Returns:

the receiver's hash.

See Also:

• Object.equals(java.lang.Object)

getHeapRoots

public Iterator getHeapRoots()

Description copied from interface: JavaStackFrame

Get the set of object roots from this stack frame.

Specified by:

getHeapRoots in interface JavaStackFrame

Returns:

an iterator of JavaReferences
