Method Detail

duplicate

public void duplicate(java.lang.Object source_)

Description copied from class: DrclObj

opies the content of the source_ object to this object. he subclass must implement this method to realize DrclObj.clone().

Specified by:

duplicate in interface ObjectDuplicable

Overrides:

duplicate in class DrclObj

clone

public java.lang.Object clone()

Description copied from class: DrclObj

Returns a clone of this object. By default, this method creates an object of the same class and calls DrclObj.duplicate(Object) to duplicate the content of this object to the newly-created one.

This method uses getClass().newInstance() to create new instance. Hence, subclasses need to override this method only if the subclass is not declared as public or does not have explicit no-argument constructor. A subclass may override this method for performance reason.

Specified by:

clone in interface ObjectDuplicable

Overrides:

clone in class DrclObj

resetPrune

public void resetPrune(BitSet dependentIfs_)

getPruneExpire

public double getPruneExpire(int index_)

setPruneExpire

public void setPruneExpire(int index_,
                           double expire_)

hasPendingGraft

public boolean hasPendingGraft()

graftAckExpBackOff

public void graftAckExpBackOff(double now_,
                               double base_)

clearPendingGraft

public void clearPendingGraft()

toString

public java.lang.String toString()

Overrides:

toString in class DrclObj
