public class CellsQueue<T,C extends Cell<T>>
extends LinkedList<C>

A special kind of LinkedList which discards the oldest added item once it reaches the set capacity.

Basically the same as CircularQueue, but automatically invokes Cell.dispose() on cell that are discarded.

Constructor Details

CellsQueue

public CellsQueue(int capacity)

Method Details

queue

public boolean queue(C c)

Adds the given cell to the queue. If at capacity, the oldest cell is disposed and discarded.

Returns:

whether the cell was added

getCapacity

public int getCapacity()

Returns:

the queue's capacity, the maximum number of cells that can be added

setCapacity

public void setCapacity(int capacity)

Sets the queue's capacity. If the parameter is 0, every cell is disposed and removed. If the new capacity is lesser than the current one, then the oldest cell is removed until the capacity is reached.
