Class ArrayKeySet<E extends Key>

java.lang.Object

org.pepstock.charba.client.commons.ArrayKeySet<E>

All Implemented Interfaces:

Iterable<E>, Collection<E>, Set<E>

public final class ArrayKeySet<E extends Key>
extends Object

A collection that contains no duplicate elements.
More formally, sets contain no pair of elements e1 and e2 such that e1.equals(e2), and at most one null element.
This implementation uses a java script object as back-end to store objects (Key values).

Some methods are annotated with @SuppressWarnings("unusable-by-js") because J2CL transpiler emits warnings as not usable in the javascript part but this collection must not be passed to any javascript code.

Method Summary

Modifier and Type	Method	Description
boolean	add(E e)	Adds the specified element to this set if it is not already present (optional operation).
boolean	addAll(Collection<? extends E> c)	Appends all of the elements in the specified collection to the end of this set, in the order that they are returned by the specified collection's iterator
void	clear()	Removes all of the elements from this set.
boolean	contains(Object object)	Returns true if this set contains the specified element.
boolean	containsAll(Collection<?> c)	Returns true if this set contains all of the elements of the specified collection.
boolean	isEmpty()	Returns true if this set contains no elements
Iterator<E>	iterator()	Returns an iterator over the elements in this set.
boolean	remove(Object o)	Removes the first occurrence of the specified element from this set, if it is present.
boolean	removeAll(Collection<?> c)	Removes from this set all of its elements that are contained in the specified collection.
boolean	retainAll(Collection<?> c)	Retains only the elements in this set that are contained in the specified collection. In other words, removes from this set all of its elements that are not contained in the specified collection.
int	size()	Returns the number of elements in this set.
Object[]	toArray()	Returns an array containing all of the elements in this set.
<T> T[]	toArray(T[] a)	Returns an array containing all of the elements in this set; the runtime type of the returned array is that of the specified array.

Constructor Detail

ArrayKeySet

public ArrayKeySet(KeyFactory<E> factory)

Creates an empty set.

Parameters:

factory - factory instance to create the key from a native one.

Method Detail

add

public boolean add(E e)

Adds the specified element to this set if it is not already present (optional operation).

size

public final int size()

Returns the number of elements in this set.

Specified by:

size in interface Collection<E>

Specified by:

size in interface Set<E>

isEmpty

public final boolean isEmpty()

Returns true if this set contains no elements

Specified by:

isEmpty in interface Collection<E>

Specified by:

isEmpty in interface Set<E>

contains

public final boolean contains(Object object)

Returns true if this set contains the specified element.

Specified by:

contains in interface Collection<E>

Specified by:

contains in interface Set<E>

iterator

public final Iterator<E> iterator()

Returns an iterator over the elements in this set.

Specified by:

iterator in interface Collection<E>

Specified by:

iterator in interface Iterable<E>
