GeodeCacheSet

public GeodeCacheSet(org.apache.geode.cache.Region region)

方法详细资料

setRegion

public void setRegion(org.apache.geode.cache.Region region)

contains

public boolean contains(T o)

从接口复制的说明: CacheSet

Returns true if this set contains the specified element. More formally, returns true if and only if this set contains an element e such that (o==null ? e==null : o.equals(e)).

指定者:

contains 在接口中 CacheSet<T extends Serializable>

参数:

o - element whose presence in this set is to be tested.

返回:

true if this set contains the specified element.

iterator

public Iterator<T> iterator()

从接口复制的说明: CacheSet

Returns an iterator over the elements in this set. The elements are returned in no particular order (unless this set is an instance of some class that provides a guarantee).

指定者:

iterator 在接口中 CacheSet<T extends Serializable>

返回:

an iterator over the elements in this set.

toSet

public Set<T> toSet()

从接口复制的说明: CacheSet

将缓存转化为Set表示。

指定者:

toSet 在接口中 CacheSet<T extends Serializable>

返回:

包含缓存中的所有对象的Set。

add

public boolean add(T o)

从接口复制的说明: CacheSet

Adds the specified element to this set if it is not already present (optional operation). More formally, adds the specified element, o, to this set if this set contains no element e such that (o==null ? e==null : o.equals(e)). If this set already contains the specified element, the call leaves this set unchanged and returns false. In combination with the restriction on constructors, this ensures that sets never contain duplicate elements.

The stipulation above does not imply that sets must accept all elements; sets may refuse to add any particular element, including null, and throwing an exception, as described in the specification for Collection.add. Individual set implementations should clearly document any restrictions on the elements that they may contain.

指定者:

add 在接口中 CacheSet<T extends Serializable>

参数:

o - element to be added to this set.

返回:

true if this set did not already contain the specified element.

remove

public boolean remove(T o)

从接口复制的说明: CacheSet

Removes the specified element from this set if it is present (optional operation). More formally, removes an element e such that (o==null ? e==null : o.equals(e)), if the set contains such an element. Returns true if the set contained the specified element (or equivalently, if the set changed as a result of the call). (The set will not contain the specified element once the call returns.)

指定者:

remove 在接口中 CacheSet<T extends Serializable>

参数:

o - object to be removed from this set, if present.

返回:

true if the set contained the specified element.

addAll

public boolean addAll(Collection<? extends T> c)

从接口复制的说明: CacheSet

Adds all of the elements in the specified collection to this set if they're not already present (optional operation). If the specified collection is also a set, the addAll operation effectively modifies this set so that its value is the union of the two sets. The behavior of this operation is unspecified if the specified collection is modified while the operation is in progress.

指定者:

addAll 在接口中 CacheSet<T extends Serializable>

参数:

c - collection whose elements are to be added to this set.

返回:

true if this set changed as a result of the call.

另请参阅:

#add(Object)

replaceAll

public void replaceAll(Collection<? extends T> set)

从接口复制的说明: CacheSet

清除缓存并将Map中的所有项目设置到缓存中。效果相当于先clear再addAll。

指定者:

replaceAll 在接口中 CacheSet<T extends Serializable>

参数:

set - Java Set

removeAll

public boolean removeAll(Collection<? extends T> c)

从接口复制的说明: CacheSet

Removes from this set all of its elements that are contained in the specified collection (optional operation). If the specified collection is also a set, this operation effectively modifies this set so that its value is the asymmetric set difference of the two sets.

指定者:

removeAll 在接口中 CacheSet<T extends Serializable>

参数:

c - collection that defines which elements will be removed from this set.

返回:

true if this set changed as a result of the call.

另请参阅:

#remove(Object)

notifyUpdate

public void notifyUpdate(T k)

从接口复制的说明: CacheSet

通知缓存项改变，需要更新。

指定者:

notifyUpdate 在接口中 CacheSet<T extends Serializable>

参数:

k - 缓存的对象

getGroup

public String getGroup()

从接口复制的说明: GroupCacheable

取得缓存所属的组。

指定者:

getGroup 在接口中 GroupCacheable

返回:

缓存所属组。

getName

public String getName()

从接口复制的说明: GroupCacheable

取得缓存名称。

指定者:

getName 在接口中 GroupCacheable

返回:

缓存名称。

size

public int size()

从接口复制的说明: GroupCacheable

Returns the number of elements in this list. If this list contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.

指定者:

size 在接口中 GroupCacheable

返回:

the number of elements in this list.

isEmpty

public boolean isEmpty()

从接口复制的说明: GroupCacheable

Returns true if this list contains no elements.

指定者:

isEmpty 在接口中 GroupCacheable

返回:

true if this list contains no elements.

clear

public void clear()

从接口复制的说明: GroupCacheable

清除所有缓存项。

指定者:

clear 在接口中 GroupCacheable

getStatistics

public CacheStatistics getStatistics()

从接口复制的说明: GroupCacheable

获取缓存统计对象。

指定者:

getStatistics 在接口中 GroupCacheable

返回:

缓存统计对象，记录缓存的访问信息。
