)

Member Function Documentation

PObject* PRFC1155_Gauge::Clone ( ) const
virtual

Create a copy of the class on the heap.

The exact semantics of the descendent class determine what is required to make a duplicate of the instance. Not all classes can even do a clone operation.

The main user of the clone function is the PDictionary class as it requires copies of the dictionary keys.

The default behaviour is for this function to assert.

Returns
pointer to new copy of the class instance.

Reimplemented from PASN_Integer.
