ml.shifu.guagua.util
类 MemoryLimitedList<T>

java.lang.Object
  ml.shifu.guagua.util.MemoryLimitedList<T>

所有已实现的接口：

Iterable<T>, AppendList<T>

public class MemoryLimitedList<T>
extends Object
implements AppendList<T>

A simple wrapper list with limited byte size.

Only two stages support in such kind of list. The first one is WRITE, the next is read. So far random WRITE and READ are not supported in this list.

If current size is over limited size, a GuaguaRuntimeException is added when #add(Object).
