java.io.OutputStream
java.io.FilterOutputStream
com.mysql.cj.protocol.x.CompressionSplittedOutputStream
All Implemented Interfaces:
java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable
public class CompressionSplittedOutputStream
extends java.io.FilterOutputStream
An OutputStream wrapper that analyzes X Protocol frames and routes them directly to the original underlying OutputStream or passes them through to a compressor-able OutputStream to compresses the frame, rebuilds it and then sends a newly compressed X Protocol frame, depending on defined data size threshold.
