类 ByteArrayOStream

java.lang.Object

java.io.OutputStream

com.vladium.util.ByteArrayOStream

所有已实现的接口:

Closeable, Flushable, AutoCloseable

public final class ByteArrayOStream
extends OutputStream

An unsynchronized version of java.io.ByteArrayOutputStream that can expose the underlying byte array without a defensive clone and can also be converted to a ByteArrayIStream without intermediate array copies.

All argument validation is disabled in release mode.

NOTE: copy-on-write not supported
