getElements

public T[] getElements()

getNumLocked

public int getNumLocked()

get

public Pool.Element<T> get()

Gets the next available resource for which the lock can be acquired and returns it and its associated lock, which needs to be released when the caller is done using the resource. If no resource in the pool can be locked, returns a newly created resource and a null lock. This means that no lock was acquired and thus doesn't need to be released.

返回:

An Element with T and a lock (possibly null if newly created)
