writeUnsharedback to summary
public void writeUnshared(final Object obj) throws IOException

Overrides org.jboss.marshalling.MarshallerObjectOutputStream.writeUnshared.

Doc from org.jboss.marshalling.MarshallerObjectOutputStream.writeUnshared.

Writes an "unshared" object to the ObjectOutputStream. This method is identical to writeObject, except that it always writes the given object as a new, unique object in the stream (as opposed to a back-reference pointing to a previously serialized instance). Specifically:

  • An object written via writeUnshared is always serialized in the same manner as a newly appearing object (an object that has not been written to the stream yet), regardless of whether or not the object has been written previously.
  • If writeObject is used to write an object that has been previously written with writeUnshared, the previous writeUnshared operation is treated as if it were a write of a separate object. In other words, ObjectOutputStream will never generate back-references to object data written by calls to writeUnshared.
While writing an object via writeUnshared does not in itself guarantee a unique reference to the object when it is deserialized, it allows a single object to be defined multiple times in a stream, so that multiple calls to readUnshared by the receiver will not conflict. Note that the rules described above only apply to the base-level object written with writeUnshared, and not to any transitively referenced sub-objects in the object graph to be serialized.

ObjectOutputStream subclasses which override this method can only be constructed in security contexts possessing the "enableSubclassImplementation" SerializablePermission; any attempt to instantiate such a subclass without this permission will cause a SecurityException to be thrown.

Parameters
obj:Object

Doc from java.io.ObjectOutputStream.writeUnshared.

object to write to stream

Exceptions
IOException:

Doc from java.io.ObjectOutputStream.writeUnshared.

if an I/O error occurs during serialization

writeUTFback to summary
public void writeUTF(final String str) throws IOException

Overrides org.jboss.marshalling.MarshallerObjectOutputStream.writeUTF.

Implements java.io.DataOutput.writeUTF.

Doc from org.jboss.marshalling.MarshallerObjectOutputStream.writeUTF.

Primitive data write of this String in modified UTF-8 format. Note that there is a significant difference between writing a String into the stream as primitive data or as an Object. A String instance written by writeObject is written into the stream as a String initially. Future writeObject() calls write references to the string into the stream.

Parameters
str:String

Doc from java.io.ObjectOutputStream.writeUTF.

the String to be written

Exceptions
IOException:

Doc from java.io.ObjectOutputStream.writeUTF.

if I/O errors occur while writing to the underlying stream
