merge(const OSSet *)

Adds the contents of an OSet to the set.

Declaration

virtual bool merge(
 const OSSet *set);

Parameters

  • set:

    The OSSet object containing the objects to be added.

Return Value

true if any object from set are successfully added the receiver (or were already present), false otherwise.

Overview

This functions adds to the receiving set all objects from set that are not already in the receiving set. Objects added to the receiver are retained.

In releases prior to 10.7, this function would return false if an object from set was already present in the set, or if set was empty. This is no longer the case, so this function correctly returns true when the semantic of merging is met.
