verifyCachedObjectForReuse

public static boolean verifyCachedObjectForReuse(Object object)

Determine whether a cached object should be reused, w.r.t. liveness. Null inputs are never safe for reuse. If the object is a LivenessReferent and not a non-refreshing DynamicNode, this method will return the result of trying to manage object with the top of the current thread's LivenessScopeStack.

Parameters:

object - The object

Returns:

True if the object did not need management, or if it was successfully managed, false otherwise
