ANTLR 3.5.3 · org.antlr.misc.IntSet

A generic set of ints that has an efficient implementation, BitSet, which is a compressed bitset and is useful for ints that are small, for example less than 500 or so, and w/o many ranges. For ranges with large values like unicode char sets, this is not very efficient. Consider using IntervalSet. Not all methods in IntervalSet are implemented.

Method Summary

Modifier and Type	Method and Description
public void	add(int el) Add an element to the set
public void	addAll(IntSet set) Add all elements from incoming set to this set.
public IntSet	and(IntSet a) Return the intersection of this set with the argument, creating a new set.
public IntSet	complement(IntSet elements)
public boolean	equals(Object obj)
public int	getSingleElement()
public boolean	isNil()
public boolean	member(int el)
public IntSet	or(IntSet a)
public void	remove(int el) remove this element from this set
public int	size() Return the size of this set (not the underlying implementation's allocated memory size, for example).
public IntSet	subtract(IntSet a)
public List<Integer>	toList()
public String	toString()
public String	toString(Grammar g)
