参数:

maxSize - The maximum size of this queue. Exceeding this limit would result in removing the oldest element (FIFO).

toArrayList

public ArrayList<T> toArrayList()

size

public int size()

Returns the number of currently stored elements.

返回:

The number of currently stored elements.

iterator

public Iterator<T> iterator()

Returns the BoundedFIFOQueue's Iterator.

指定者:

iterator 在接口中 Iterable<T>

返回:

The queue's Iterator.
