Method Detail

newInstance

public static PrepareStatementCache newInstance(int size,
                                                Protocol protocol)

removeEldestEntry

public boolean removeEldestEntry(Map.Entry eldest)

Remove eldestEntry.

Overrides:

removeEldestEntry in class LinkedHashMap<String,PrepareResult>

Parameters:

eldest - eldest entry

Returns:

true if eldest entry must be removed

put

public PrepareResult put(String key,
                         PrepareResult result,
                         boolean force)

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.

Parameters:

key - key

result - new prepare result.

force - flag to indicate if cache must be forced (after a failover)

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,PrepareResult>
