方法详细资料

contains

public boolean contains(V 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)).

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 java.util.Iterator<V> 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).

返回:

an iterator over the elements in this set.

toSet

public java.util.Set<V> toSet()

从接口复制的说明: CacheSet

将缓存转化为Set表示。

返回:

包含缓存中的所有对象的Set。

add

public int add(V 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.

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 int remove(V 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.)

参数:

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

返回:

true if the set contained the specified element.

addAll

public int addAll(java.util.Collection<? extends V> 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.

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.

clearAndAddAll

public int clearAndAddAll(java.util.Collection<? extends V> c)

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。

参数:

c - Java Set

removeAll

public int removeAll(java.util.Collection<? extends V> keys)

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.

参数:

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

返回:

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

size

public int size()

从接口复制的说明: GroupCacheable

该方法提供的为本地大小，不代表Redis缓存大小，谨慎使用 Returns the number of elements in this list. If this list contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.

返回:

the number of elements in this list.

clear

public void clear()

从接口复制的说明: GroupCacheable

清除所有缓存项。

allowRedisFlush

public boolean allowRedisFlush()

从接口复制的说明: GroupCacheable

检查是否按需或者可以补偿回来

needConsistent

public boolean needConsistent()

从接口复制的说明: GroupCacheable

是否需要保持一级缓存一致性

pop

public V pop()

从接口复制的说明: CacheSet

remove and return the random value in the Set.

返回:
