public class parse_action_table
extends java.lang.Object
This class represents the complete "action" table of the parser.
It has one row for each state in the parse machine, and a column for
each terminal symbol. Each entry in the table represents a shift,
reduce, or an error.
_num_states
protected int _num_states
How many rows/states are in the machine/table.
under_state
public parse_action_row[] under_state
Actual array of rows, one per state.
parse_action_table
public parse_action_table()
Simple constructor. All terminals, non-terminals, and productions must
already have been entered, and the viable prefix recognizer should
have been constructed before this is called.
check_reductions
public void check_reductions()
throws internal_error
Check the table to ensure that all productions have been reduced.
Issue a warning message (to System.err) for each production that
is never reduced.
num_states
public int num_states()
How many rows/states are in the machine/table.
