java.lang.Object
  com.sun.squawk.util.IntSet

public final class IntSet
extends Object

The IntSet class is an unsynchronized set of integers. The main operations are add, remove, size, and getInts.

Field Summary

protected int	elementCount The number of valid components in the vector.
protected int[]	elementData The array buffer into which the components of the vector are stored.

Constructor Summary

IntSet()
Constructs an empty vector.

IntSet(int initialCapacity)
Constructs an empty vector with the specified initial capacity and capacity increment.

Method Summary

void	add(int val) Adds the specified int to this set,, increasing its size by one.
boolean	contains(int elem) Tests if the specified object is a component in this vector.
int[]	getElements() Returns the underlying int array.
boolean	remove(int val) Removes the first occurrence of the argument from this set.
void	removeAll() Removes all components from this vector and sets its size to zero.
int	size() Returns the number of components in this set.

elementCount

protected int elementCount

The number of valid components in the vector.

Constructor Detail

IntSet

public IntSet(int initialCapacity)

Constructs an empty vector with the specified initial capacity and capacity increment.

Parameters:

initialCapacity - the initial capacity of the vector.

Throws:

IllegalArgumentException - if the specified initial capacity is negative

IntSet

public IntSet()

Constructs an empty vector.

Method Detail

getElements

public int[] getElements()

Returns the underlying int array. Only iterate over first size() elements.

Returns:

underlying int array

size

public final int size()

Returns the number of components in this set.

Returns:

the number of components in this set.

contains

public final boolean contains(int elem)

Tests if the specified object is a component in this vector.

Parameters:

elem - an object.

Returns:

true if the specified object is a component in this vector; false otherwise.

add

public void add(int val)

Adds the specified int to this set,, increasing its size by one.

Parameters:

val - the component to be added.

remove

public boolean remove(int val)

Removes the first occurrence of the argument from this set.

Parameters:

val - the component to be removed.

Returns:

true if the argument was a component of this set; false otherwise.

removeAll
