getReferenceCount

public int getReferenceCount()

Description copied from interface: PoolableSetIF

INTERNAL: Return the current reference count. The reference count is used to control the life cycle of the pooled set. The pool instance that manages this set will use the reference count to figure out when to drop the set from its pool.

Specified by:

getReferenceCount in interface PoolableSetIF

referenced

public int referenced(SetPoolIF pool)

Description copied from interface: PoolableSetIF

INTERNAL: Increment and return reference count.

Specified by:

referenced in interface PoolableSetIF

dereferenced

public int dereferenced(SetPoolIF pool)

Description copied from interface: PoolableSetIF

INTERNAL: Decrement and return reference count.

Specified by:

dereferenced in interface PoolableSetIF

equalsAdd

public boolean equalsAdd(java.util.Set other,
                         java.lang.Object o)

Description copied from interface: PoolableSetIF

INTERNAL: Returns true if the given set will be equal to this set if the given object had been added to this set.

Specified by:

equalsAdd in interface PoolableSetIF

equalsRemove

public boolean equalsRemove(java.util.Set other,
                            java.lang.Object o)
