GSetByHashMap

public GSetByHashMap(int initialCapacity,
             float loadFactor)

方法详细资料

size

public int size()

指定者:

size 在接口中 GSet<K,E extends K>

返回:

The size of this set.

contains

public boolean contains(K k)

从接口复制的说明: GSet

Does this set contain an element corresponding to the given key?

指定者:

contains 在接口中 GSet<K,E extends K>

参数:

k - The given key.

返回:

true if the given key equals to a stored element. Otherwise, return false.

get

public E get(K k)

从接口复制的说明: GSet

Return the stored element which is equal to the given key. This operation is similar to Map.get(Object).

指定者:

get 在接口中 GSet<K,E extends K>

参数:

k - The given key.

返回:

The stored element if it exists. Otherwise, return null.

put

public E put(E element)

从接口复制的说明: GSet

Add/replace an element. If the element does not exist, add it to the set. Otherwise, replace the existing element. Note that this operation is similar to Map.put(Object, Object) but is different from Set.add(Object) which does not replace the existing element if there is any.

指定者:

put 在接口中 GSet<K,E extends K>

参数:

element - The element being put.

返回:

the previous stored element if there is any. Otherwise, return null.

remove

public E remove(K k)

从接口复制的说明: GSet

Remove the element corresponding to the given key. This operation is similar to Map.remove(Object).

指定者:

remove 在接口中 GSet<K,E extends K>

参数:

k - The key of the element being removed.

返回:

If such element exists, return it. Otherwise, return null.

iterator

public Iterator<E> iterator()

指定者:

iterator 在接口中 Iterable<E extends K>

clear

public void clear()

指定者:

clear 在接口中 GSet<K,E extends K>
