Method Summary
 java.lang.Object[] getAllPaths(IProgressListener progressListener)
          Calculates (if not yet calculated) and returns all the paths.
 MultiplePathsFromGCRootsRecord[] getPathsByGCRoot(IProgressListener progressListener)
          Calculates (if not yet calculated) and returns all the paths.
 

Method Detail

getPathsByGCRoot

MultiplePathsFromGCRootsRecord[] getPathsByGCRoot(IProgressListener progressListener)
                                                  throws SnapshotException
Calculates (if not yet calculated) and returns all the paths. The paths are grouped by the GC root object, i.e. all paths starting from one and the same GC root will be packed in one MultiplePathsFromGCRootsRecord. This record can be used to get the objects at the next level in the path, etc...

Parameters:
progressListener - - used to track the progress of the computation
Returns:
MultiplePathsFromGCRootsRecord[] one record for each group of paths starting from the same GC root
Throws:
SnapshotException

getAllPaths

java.lang.Object[] getAllPaths(IProgressListener progressListener)
                               throws SnapshotException
Calculates (if not yet calculated) and returns all the paths. Each element in the Object[] is an int[] representing the path. The first element in the int[] is the specified object, and the last is the GC root object

Parameters:
progressListener - - used to track the progress of the computation
Returns:
Object[] - each element in the array is an int[] representing a path
Throws:
SnapshotException
