newInstance
public static ServerPrepareStatementCache newInstance(int size, Protocol protocol)
-
removeEldestEntry
public boolean removeEldestEntry(Map.Entry eldest)
Remove eldestEntry.- Overrides:
removeEldestEntry
in classLinkedHashMap<String,ServerPrepareResult>
- Parameters:
eldest
- eldest entry- Returns:
- true if eldest entry must be removed
-
put
public ServerPrepareResult put(String key, ServerPrepareResult result)
Associates the specified value with the specified key in this map. If the map previously contained a mapping for the key, the existing cached prepared result shared counter will be incremented.- Specified by:
put
in interfaceMap<String,ServerPrepareResult>
- Overrides:
put
in classHashMap<String,ServerPrepareResult>
- Parameters:
key
- keyresult
- new prepare result.- Returns:
- the previous value associated with key if not been deallocate, or null if there was no mapping for key.
-
toString
public String toString()
