question: public void add ( Comparator c ) { if ( c == null ) return ; if ( m_cmp . length == m_size ) { Comparator [ ] cmp = new Comparator [ m_size + INCREMENT ] ; System . arraycopy ( m_cmp , 0 , cmp , 0 , m_size ) ; m_cmp = cmp ; } m_cmp [ m_size ++ ] = c ; }
target:  Adds an additional comparator to this composite.
