Method Details
-
nextLevel
Go down to the next level- Returns:
- an array of records from the next level
- Throws:
SnapshotException
-
addPath
public void addPath(int[] path) This method is used only when the record is built. Adds one path to the set of paths- Parameters:
path-
-
getPaths
Get all the paths going through the object (getObjectId())- Returns:
- List<int[]> each element in the list is an int[] representing a path
-
getCount
public int getCount()Get the number of paths going through this object -
getDistinctCount
public int getDistinctCount()Get the number of distinct objects of this class -
getReferencedHeapSize
Get the total net heap size of all referenced objects (see getReferencedObjects())- Returns:
- - the total heap size of all referenced objects
- Throws:
SnapshotException
-
getReferencedObjects
public int[] getReferencedObjects()Get the "end" objects for each path. This is equal to getting all the paths and looking at their element [0]- Returns:
- - an array with all the objects at the end of the paths
-

public static Comparator<MultiplePathsFromGCRootsClassRecord> getComparatorByNumberOfReferencedObjects() -
getComparatorByReferencedHeapSize
Returns a Comparator ordering the records descending by the total size of referenced objects. -
