Method Detail

newInstance

public static ServerPrepareStatementCache newInstance(int size,
                                                      Protocol protocol)

removeEldestEntry

public boolean removeEldestEntry(java.util.Map.Entry eldest)

Remove eldestEntry.

Overrides:

removeEldestEntry in class java.util.LinkedHashMap<java.lang.String,ServerPrepareResult>

Parameters:

eldest - eldest entry

Returns:

true if eldest entry must be removed

put

public ServerPrepareResult put(java.lang.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 java.util.Map<java.lang.String,ServerPrepareResult>

Overrides:

put in class java.util.HashMap<java.lang.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 java.lang.String toString()

Overrides:

toString in class java.util.AbstractMap<java.lang.String,ServerPrepareResult>
