Package com.tangosol.util

Class NullImplementation.NullOutputStream

java.lang.Object

java.io.OutputStream

com.tangosol.util.NullImplementation.NullOutputStream

All Implemented Interfaces:

com.oracle.coherence.common.io.OutputStreaming, OutputStreaming, Closeable, DataOutput, Flushable, AutoCloseable

Enclosing class:

NullImplementation

public static class NullImplementation.NullOutputStream
extends OutputStream
implements OutputStreaming, DataOutput

An OutputStream that does basically nothing. Note that multiple instances are required because the API dictates that the close method must cause further invocations to all other methods to throw an IOException.
