Constructor Detail

IntegerSet

public IntegerSet(int maximumCount)

Initialize a lookup table with the given maximum number of elements.

This creates a set for elements in the range [0, count).

Formally, the current set must be a subset of [0, 1, 2, ..., count - 1].

Parameters:

maximumCount - - maximum element value and count.

Method Detail

contains

public boolean contains(int element)

Determine whether or not the given element exists in the set.

Parameters:

element - - the element to check. Must be in the range [0, count).

Returns:

TRUE if the given element exists, FALSE otherwise.

add

public void add(int element)

Add the given element to the set, or do nothing if it already exists.

Parameters:

element - - element to add.

Throws:

OutOfBoundsException - If the given element is not in the range [0, count).

addAll

public void addAll(java.util.Collection<java.lang.Integer> packets)

Add the given collection of elements to the set.

Parameters:

packets - - elements to add.

remove

public void remove(int element)

Remove the given element from the set, or do nothing if it's already removed.

Parameters:

element - - element to remove.

clear

public void clear()

Remove every element from the set.

toSet

public java.util.Set<java.lang.Integer> toSet()

Convert the current IntegerSet to an equivalent HashSet.

Returns:

The resulting HashSet.
