Class PipelineOutputStream

java.lang.Object

java.io.OutputStream

org.greenrobot.essentials.io.PipelineOutputStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable

public class PipelineOutputStream
extends java.io.OutputStream

Replacement for Java's PipedOutputStream: all data written to this stream will get available in the integrated InputStream (see getInputStream()).

Note: Usually, you will have exactly two threads: one to write and one to read. If you use a single thread, avoid reading more bytes than previously written or writing more bytes than the internal buffer can handle.
