构造器详细资料

RongCacheWrap

public RongCacheWrap(RongContext context,
                     int maxSize)

参数:

maxSize - for caches that do not override RongCache.sizeOf(K, V), this is the maximum number of entries in the cache. For all other caches, this is the maximum sum of the sizes of the entries in this cache.

isIsSync

public boolean isIsSync()

setIsSync

public void setIsSync(boolean isSync)

create

protected V create(K key)

从类复制的说明: RongCache

Called after a cache miss to compute a value for the corresponding key. Returns the computed value or null if no value can be computed. The default implementation returns null.

The method is called without synchronization: other threads may access the cache while this method is executing.

If a value for key exists in the cache when this method returns, the created value will be released with RongCache.entryRemoved(boolean, K, V, V) and discarded. This can occur when multiple threads request the same key at the same time (causing multiple values to be created), or when one thread calls RongCache.put(K, V) while another is creating a value for the same key.
