iterate(HeapVisitor visitor)
The base heap iteration mechanism
|
void |
iterate(HeapVisitor visitor,
ObjectHeap.ObjectFilter of)
iterate objects satisfying a specified ObjectFilter
|
void |
iterateObjectsOfKlass(HeapVisitor visitor,
Klass k)
iterate objects of given Klass (objects of subtypes included)
|
void |
iterateObjectsOfKlass(HeapVisitor visitor,
Klass k,
boolean includeSubtypes)
iterate objects of given Klass.
|
void |
iterateRaw(RawHeapVisitor visitor)
This routine can be used to iterate through the heap at an
extremely low level (stepping word-by-word) to provide the
ability to do very low-level debugging

typeArrayKlassObj(int t)
Takes a BasicType and returns the corresponding primitive array
