terminal

• java.lang.Object
  • symbol

Fields Summary
private int	_precedence_num
private int	_precedence_side
protected static Hashtable	_all Table of all terminals. Elements are stored using name strings as the key
protected static Hashtable	_all_by_index Table of all terminals indexed by their index number.
protected static int	next_index Static counter to assign unique index.
public static final terminal	EOF Special terminal for end of input.
public static final terminal	error special terminal used for error recovery

Constructors Summary
public terminal(String nm, String tp, int precedence_side, int precedence_num) Full constructor. param nm the name of the terminal. param tp the type of the terminal. /* superclass does most of the work */ super(nm, tp); /* add to set of all terminals and check for duplicates */ Object conflict = _all.put(nm,this); if (conflict != null) // can't throw an execption here because this is used in static // initializers, so we do a crash instead // was: // throw new internal_error("Duplicate terminal (" + nm + ") created"); (new internal_error("Duplicate terminal (" + nm + ") created")).crash(); /* assign a unique index */ _index = next_index++; /* set the precedence */ _precedence_num = precedence_num; _precedence_side = precedence_side; /* add to by_index set */ _all_by_index.put(new Integer(_index), this);
public terminal(String nm, String tp) Constructor for non-precedented terminal this(nm, tp, assoc.no_prec, -1);
public terminal(String nm) Constructor with default type. param nm the name of the terminal. this(nm, null);

Methods Summary
public static java.util.Enumeration	all() Access to all terminals. return _all.elements();
public static com.sun.java_cup.internal.terminal	find(java.lang.String with_name) Lookup a terminal by name string. if (with_name == null) return null; else return (terminal)_all.get(with_name);
public static com.sun.java_cup.internal.terminal	find(int indx) Lookup a terminal by index. Integer the_indx = new Integer(indx); return (terminal)_all_by_index.get(the_indx);
public boolean	is_non_term() Report this symbol as not being a non-terminal. /*-----------------------------------------------------------*/ /*--- General Methods ---------------------------------------*/ /*-----------------------------------------------------------*/ return false;
public static int	number() Total number of terminals. return _all.size();
public int	precedence_num() get the precedence of a terminal return _precedence_num;
public int	precedence_side() return _precedence_side;
public void	set_precedence(int p, int new_prec) set the precedence of a terminal _precedence_side = p; _precedence_num = new_prec;
public java.lang.String	toString() Convert to a string. return super.toString() + "[" + index() + "]";
