const PObject &

obj

)

const [inline, virtual]

Compare the two objects and return their relative rank. This function is usually overridden by descendent classes to yield the ranking according to the semantics of the object.

The default function is to use the CompareObjectMemoryDirect()# function to do a byte wise memory comparison of the two objects.

Returns:

LessThan#, EqualTo# or GreaterThan# according to the relative rank of the objects.

Parameters:

obj	Object to compare against.
