| <P><SAMP>not1()</SAMP> is a function adaptor, known as a negator, that takes a unary predicate function object as its argument and returns a unary predicate function object that is the complement of the original. <B><I><A HREF="unary-negate.html">unary_negate</A></I></B> is the function object class used for a return type for the <SAMP>not1()</SAMP> negator. </P> |
