question: public void debug_stack ( ) { StringBuffer sb = new StringBuffer ( "## STACK:" ) ; for ( int i = 0 ; i < stack . size ( ) ; i ++ ) { Symbol s = ( Symbol ) stack . elementAt ( i ) ; sb . append ( " <state " + s . parse_state + ", sym " + s . sym + ">" ) ; if ( ( i % 3 ) == 2 || ( i == ( stack . size ( ) - 1 ) ) ) { debug_message ( sb . toString ( ) ) ; sb = new StringBuffer ( "         " ) ; } } }
target:  Do debug output for stack state. [CSA]
