All Implemented Interfaces:

Closeable, DataOutput, Flushable, ObjectOutput, ObjectStreamConstants, AutoCloseable, ObjectStreamContext

Enclosing class:

MarshalledInstance

private static class MarshalledInstance.MarshalledInstanceOutputStream
extends MarshalOutputStream

This class is used to marshal objects for MarshalledInstance. It places the location annotations to one side so that two MarshalledInstances can be compared for equality if they differ only in location annotations. Objects written using this stream should be read back from a MarshalledInstanceInputStream.

                                      OutputStream locOut,
                                      Collection context)
                               throws IOException

Creates a new MarshalledObjectOutputStream whose non-location bytes will be written to objOut and whose location annotations (if any) will be written to locOut.

Throws:

IOException

Method Detail

hadAnnotations

public boolean hadAnnotations()

Returns true if any non-null location annotations have been written to this stream.

writeAnnotation

protected void writeAnnotation(String loc)
