Package org.fusesource.hawtbuf

Class BufferOutputStream

  • All Implemented Interfaces:
    java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable
    public final class BufferOutputStream
extends java.io.OutputStream
    Very similar to the java.io.ByteArrayOutputStream but this version is not thread safe and the resulting data is returned in a Buffer to avoid an extra byte[] allocation. It also does not re-grow it's internal buffer.
