 package org.netbeans.insane.live;

A live references engine entry point. Provides a means for tracing root-paths of given heap objects.

Author(s):
nenik
 
 public final class LiveReferences {
    
    
Traces the heap from known roots until all of the objects in objs are found or all of the reachable heap is covered. This call is highly time consuming and can block all of the application, so it is mostly useful for debugging and runtime field analysis.

Parameters:
objs a Collection of objects to trace
Returns:
a map with one entry for each found object that maps from the object to a Path instance.
 
     public static Map<Object,PathfromRoots(Collection<Objectobjs) {
         return new LiveEngine().trace(objsnull);
     }

    
Traces the heap from known roots until all of the objects in objs are found or all of the reachable heap is covered. This call is highly time consuming and can block all of the application, so it is mostly useful for debugging and runtime field analysis. This variant allows approximate tracking of the scan progress, but for real visual feedback, paintImmediatelly might be necessary.

Parameters:
objs a Collection of objects to trace
rootsHint a set of Object that should be considered roots. Can be null.
progress a model of a ProgressBar to be notified during the scan. Can be null.
Returns:
a map with one entry for each found object that maps from the object to a Path instance.
 
     public static Map<Object,PathfromRoots(Collection<ObjectobjsSet<ObjectrootsHintBoundedRangeModel progress) {
         return new LiveEngine(progress).trace(objsrootsHint);
     }

f the org.netbeans.insane.scanner.Filter to apply on heap's live objects.
