Class IOWritePool

java.lang.Object

net.lecousin.framework.io.IOWritePool

public class IOWritePool
extends Object

This class can be used if you are writing to a IO.Writable, but you don't want to wait for the previous write to be done before to write again. When writing to this class, if the previous write is not yet finished, the buffer is pushed to a queue, and will be written as soon as the previous write is finished. At the end of all write operations, you can use the method onDone to get a synchronization point that will be unblocked as soon as the last write operation is finished.
In case of many write operations, this class may queue many buffers to be written, then using an important amount of memory. You can consider using LimitWriteOperations class instead.
