方法详细资料

get

T get()

Returns an instance from the pool. The call may be a blocking one or a non-blocking one and that is determined by the internal implementation. If the call is a blocking call, the call returns immediately with a valid object if available, else the thread is made to wait until an object becomes available. In case of a blocking call, it is advised that clients react to InterruptedException which might be thrown when the thread waits for an object to become available. If the call is a non-blocking one, the call returns immediately irrespective of whether an object is available or not. If any object is available the call returns it else the call returns null. The validity of the objects are determined using the Validator interface, such that an object o is valid if Validator.isValid(o) == true

返回:

T one of the pooled objects.

release

void release(T t)

Releases the object and puts it back to the pool. The mechanism of putting the object back to the pool is generally asynchronous, however future implementations might differ.

参数:

t - the object to return to the pool

size

int size()

cleanup

void cleanup()
