public ArraySet(java.lang.Class<T> clazz)

Method Detail

addAll

public final boolean addAll(T... elements)

Add the element(s) to the set.

Parameters:

elements - the elements to add.

Returns:

true, if at least one element was added to the set and, as result, the size of the set was increased, or false, all element(s) was/were present in the set and, as the result, the set values were just reset.

addAll

public boolean addAll(java.util.Collection<? extends T> collection)

Specified by:

addAll in interface java.util.Collection<T>

Specified by:

addAll in interface java.util.Set<T>

add

public final boolean add(ArraySet<T> source)

Add all the elements from the source ArraySet.

Parameters:

source - the elements to add.

Returns:

true, if at least one element was added to the set and, as result, the size of the set was increased, or false, all element(s) was/were present in the set and, as the result, the set values were just reset.

removeAll

public final boolean removeAll(java.lang.Object... elements)

Remove element(s) from the set.

Parameters:

elements - the element(s) to remove.

Returns:

true, if at least one element was found and removed, or false otherwise.

getArray

public final T[] getArray()

Get the underlying array. Please note, it's not appropriate to modify the returned array's content. Please use add(Object) and remove(Object) instead.

Returns:

the array.

getArrayCopy

public final T[] getArrayCopy()

Get the copy of the underlying array. If the underlying array is null - then null will be returned.

Returns:

the copy of the underlying array. If the underlying array is null - then null will be returned.

obtainArrayCopy

public final T[] obtainArrayCopy()

Get the copy of the underlying array. If the underlying array is null - then empty array will be returned.

Returns:

the copy of the underlying array. If the underlying array is null - then empty array will be returned.
