Class IntPresentSet

java.lang.Object
  org.intermine.util.IntPresentSet

public class IntPresentSet
extends java.lang.Object

This is a set of ints. This class provides methods to insert an int, check for the presence of a given int, and remove an int from the set. This class is designed to use as little RAM as possible, and assumes that the ints are reasonably closely-spaced. In the case where the ints are consecutive, this class will use not much more than an eighth of a byte per mapping.
