Constructor Detail

ConcurrentIntSet

public ConcurrentIntSet()

Creates a new set with an initial capacity of 51 and a load factor of 0.8.

ConcurrentIntSet

public ConcurrentIntSet(int initialCapacity)

Creates a new set with a load factor of 0.8.

Parameters:

initialCapacity - If not a power of two, it is increased to the next nearest power of two.

ConcurrentIntSet

public ConcurrentIntSet(int initialCapacity,
                        float loadFactor)

Creates a new set with the specified initial capacity and load factor. This set will hold initialCapacity items before growing the backing table.

Parameters:

initialCapacity - If not a power of two, it is increased to the next nearest power of two.

loadFactor -

ConcurrentIntSet

public ConcurrentIntSet(org.mini2Dx.gdx.utils.IntSet set)

Creates a new set identical to the specified set. NOTE: read access to the other set is not thread-safe

Parameters:

set -

Method Detail

size

public int size()

Returns the size in a thread-safe manner

Returns:

0 if empty

add

public boolean add(int key)

Returns true if the key was not already in the set.

Overrides:

add in class org.mini2Dx.gdx.utils.IntSet

Parameters:

key -

addAll

public void addAll(org.mini2Dx.gdx.utils.IntArray array,
                   int offset,
                   int length)

Overrides:

addAll in class org.mini2Dx.gdx.utils.IntSet

addAll

public void addAll(int[] array,
                   int offset,
                   int length)

Overrides:

addAll in class org.mini2Dx.gdx.utils.IntSet

addAll

public void addAll(org.mini2Dx.gdx.utils.IntSet set)

Overrides:

addAll in class org.mini2Dx.gdx.utils.IntSet

remove

public boolean remove(int key)

Returns true if the key was removed.

Overrides:

remove in class org.mini2Dx.gdx.utils.IntSet

Parameters:

key -

notEmpty

public boolean notEmpty()

Returns true if the set has one or more items.

Overrides:

notEmpty in class org.mini2Dx.gdx.utils.IntSet

isEmpty

public boolean isEmpty()

Returns true if the set is empty.

Overrides:

isEmpty in class org.mini2Dx.gdx.utils.IntSet

shrink

public void shrink(int maximumCapacity)

Reduces the size of the backing arrays to be the specified capacity or less. If the capacity is already less, nothing is done. If the set contains more items than the specified capacity, the next highest power of two capacity is used instead.

Overrides:

shrink in class org.mini2Dx.gdx.utils.IntSet

Parameters:

maximumCapacity -

clear

public void clear(int maximumCapacity)

Clears the set and reduces the size of the backing arrays to be the specified capacity if they are larger.

Overrides:

clear in class org.mini2Dx.gdx.utils.IntSet

Parameters:

maximumCapacity -

clear

public void clear()

Overrides:

clear in class org.mini2Dx.gdx.utils.IntSet

contains

public boolean contains(int key)

Overrides:

contains in class org.mini2Dx.gdx.utils.IntSet

first

public int first()

Overrides:

first in class org.mini2Dx.gdx.utils.IntSet

ensureCapacity

public void ensureCapacity(int additionalCapacity)

Increases the size of the backing array to accommodate the specified number of additional items. Useful before adding many items to avoid multiple backing array resizes.

Overrides:

ensureCapacity in class org.mini2Dx.gdx.utils.IntSet

Parameters:

additionalCapacity -

hashCode

public int hashCode()

Overrides:

iterator

public org.mini2Dx.gdx.utils.IntSet.IntSetIterator iterator()

Returns an iterator for the keys in the set. Remove is supported.

public org.mini2Dx.lockprovider.ReadWriteLock getLock()

Description copied from interface: ConcurrentCollection

Returns the collection's ReadWriteLock

Specified by:

getLock in interface ConcurrentCollection

Returns:

the collection's ReadWriteLock
