Method Details

getPathsByGCRoot

public MultiplePathsFromGCRootsRecord[] getPathsByGCRoot(IProgressListener progressListener)
                                                  throws SnapshotException

Description copied from interface: IMultiplePathsFromGCRootsComputer

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...

Specified by:

getPathsByGCRoot in interface IMultiplePathsFromGCRootsComputer

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

public Object[] getAllPaths(IProgressListener progressListener)
                     throws SnapshotException

Description copied from interface: IMultiplePathsFromGCRootsComputer

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

Specified by:

getAllPaths in interface IMultiplePathsFromGCRootsComputer

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

getPathsGroupedByClass

public MultiplePathsFromGCRootsClassRecord[] getPathsGroupedByClass(boolean startFromTheGCRoots,
 IProgressListener progressListener)
                                                             throws SnapshotException

Throws:

SnapshotException
