Description copied from interface: Cache

Get method to retrieve value from cache Must not raise exception if the key is null, but return null

Parameters:

key - the string key

Returns:

the Serializable value, return null if the key does not exist or if the key is null

put

public void put(String key,
                Serializable value)

Description copied from interface: Cache

Put method to store a Serializable value

Parameters:

key - the string key, if null, the value will not be stored

value - the value to store, if null, the value will not be stored

hasEntry

public boolean hasEntry(String key)

Description copied from interface: Cache

Check if a given key is present inside the cache. Compared to the get() method, this method must not update internal cache state and change TTL

Specified by:

hasEntry in interface Cache

Overrides:

hasEntry in class AbstractCache
