构造器详细资料

FIFOMemoryCache

public FIFOMemoryCache(int size)

方法详细资料

getName

public String getName()

从接口复制的说明: Cache

Return the cache name.

指定者:

getName 在接口中 Cache

setName

public void setName(String name)

getSize

public int getSize()

setSize

public void setSize(int size)

get

public <T> T get(Object key,
                 Class<T> type)

从接口复制的说明: Cache

Return the value to which this cache maps the specified key, generically specifying a type that return value will be cast to.

Note: This variant of get does not allow for differentiating between a cached null value and no cache entry found at all. Use the standard #get(Object) variant for that purpose instead.

指定者:

get 在接口中 Cache

参数:

key - the key whose associated value is to be returned

type - the required type of the returned value (may be null to bypass a type check; in case of a null value found in the cache, the specified type is irrelevant)

返回:

the value to which this cache maps the specified key (which may be null itself), or also null if the cache contains no mapping for this key

另请参阅:

#get(Object)

put

public void put(Object key,
                Object value)

从接口复制的说明: Cache

Associate the specified value with the specified key in this cache.

If the cache previously contained a mapping for this key, the old value is replaced by the specified value.

指定者:

put 在接口中 Cache

参数:

key - the key with which the specified value is to be associated

value - the value to be associated with the specified key

evict

public void evict(Object key)

从接口复制的说明: Cache

Evict the mapping for this key from this cache if it is present.

指定者:

evict 在接口中 Cache

参数:

key - the key whose mapping is to be removed from the cache

clear

public void clear()

从接口复制的说明: Cache

Remove all mappings from the cache.

指定者:

clear 在接口中 Cache
