方法详细资料

newInstance

public static ServerPrepareStatementCache newInstance(int size,
                                                      Protocol protocol)

removeEldestEntry

public boolean removeEldestEntry(Map.Entry eldest)

Remove eldestEntry.

覆盖:

removeEldestEntry 在类中 LinkedHashMap<String,ServerPrepareResult>

参数:

eldest - eldest entry

返回:

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.

指定者:

put 在接口中 Map<String,ServerPrepareResult>

覆盖:

put 在类中 HashMap<String,ServerPrepareResult>

参数:

key - key

result - new prepare result.

返回:

the previous value associated with key if not been deallocate, or null if there was no mapping for key.

toString

public String toString()

覆盖:

toString 在类中 AbstractMap<String,ServerPrepareResult>
