Method Detail

newInstance

public static ServerPrepareStatementCache newInstance(int size,
                                                      Protocol protocol)

removeEldestEntry

public boolean removeEldestEntry(Map.Entry eldest)

Remove eldestEntry.

Overrides:

removeEldestEntry in class LinkedHashMap<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 interface Map<String,ServerPrepareResult>

Overrides:

put in class HashMap<String,ServerPrepareResult>

Parameters:

key - key

result - 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()

Overrides:

toString in class AbstractMap<String,ServerPrepareResult>
