Method Detail

add

public boolean add(T o)

Specified by:

add in interface java.util.Collection<T>

Overrides:

add in class java.util.AbstractCollection<T>

addAll

public boolean addAll(ObjectCollection<T> c)

Description copied from interface: ObjectCollection

A Type-Specific addAll function to reduce (un)boxing

Specified by:

addAll in interface ObjectCollection<T>

Overrides:

addAll in class AbstractObjectCollection<T>

Parameters:

c - the collection of elements that should be added

Returns:

true if elements were added into the collection

addAll

public boolean addAll(T[] e,
                      int offset,
                      int length)

Description copied from interface: ObjectCollection

A Type-Specific Array based addAll method to reduce the amount of Wrapping

Parameters:

e - the elements that should be added

offset - where to start within the array

length - how many elements of the array should be added

Returns:

if the collection was modified

contains

public boolean contains(java.lang.Object o)

Specified by:

contains in interface java.util.Collection<T>

Overrides:

contains in class java.util.AbstractCollection<T>

containsAny

public boolean containsAny(java.util.Collection<?> c)

Description copied from class: AbstractObjectCollection

This implementation iterates over the elements of the collection and checks if they are stored in this collection

Specified by:

containsAny in interface ObjectCollection<T>

Overrides:

containsAny in class AbstractObjectCollection<T>

Parameters:

c - the elements that should be checked for

Returns:

true if any element is in this collection

Specified by:

containsAll in interface java.util.Collection<T>

Overrides:

containsAll in class AbstractObjectCollection<T>

hashCode

Specified by:

equals in interface java.util.Collection<T>

Overrides:

equals in class java.lang.Object

remove

@Deprecated
public boolean remove(java.lang.Object o)

Deprecated.

Specified by:

Specified by:

removeAll in interface ObjectCollection<T>

Overrides:

removeAll in class AbstractObjectCollection<T>

Parameters:

c - the elements that should be deleted

Returns:

true if the collection was modified.

See Also:

Collection.removeAll(Collection)

retainAll

public boolean retainAll(ObjectCollection<T> c)

Description copied from class: AbstractObjectCollection

A Type-Specific implementation of retainAll. This Implementation iterates over all elements and removes them as they were not found in the other collection.

Specified by:

retainAll in interface ObjectCollection<T>

Overrides:

retainAll in class AbstractObjectCollection<T>

Parameters:

Description copied from interface: ObjectCollection

Returns a Type-Specific Iterator to reduce (un)boxing

Specified by:

iterator in interface java.lang.Iterable<T>

Specified by:

iterator in interface java.util.Collection<T>

Specified by:

iterator in interface ObjectCollection<T>

Specified by:

iterator in interface ObjectIterable<T>

Specified by:

iterator in class AbstractObjectCollection<T>

Returns:

a iterator of the collection

clear in interface java.util.Collection<T>

Overrides:

clear in class java.util.AbstractCollection<T>

size

public int size()

Specified by:

size in interface java.util.Collection<T>

Specified by:

size in class java.util.AbstractCollection<T>

copy

public ObjectCollections.EmptyCollection<T> copy()

Description copied from interface: ObjectCollection

A Function that does a shallow clone of the Collection itself. This function is more optimized then a copy constructor since the Collection does not have to be unsorted/resorted. It can be compared to Cloneable but with less exception risk

Specified by:

copy in interface ObjectCollection<T>

Overrides:

copy in class AbstractObjectCollection<T>

Returns:

a Shallow Copy of the collection
