XMLDecoder JDK 1.6)

Description

public class XMLDecoder

The XMLDecoder class is used to read XML documents created using the XMLEncoder and is used just like the ObjectInputStream.

The XMLDecoder class is used to read XML documents created using the XMLEncoder and is used just like the ObjectInputStream. For example, one can use the following fragment to read the first object defined in an XML document written by the XMLEncoder class:

       XMLDecoder d = new XMLDecoder(
                          new BufferedInputStream(
                              new FileInputStream("Test.xml")));
       Object result = d.readObject();
       d.close();

Constructors

public XMLDecoder (InputStream in)

Creates a new input stream for reading archives created by the XMLEncoder class.

Creates a new input stream for reading archives
created by the XMLEncoder class.
Parameters:
- in - The underlying stream.
See Also: XMLEncoder.XMLEncoder(java.io.OutputStream),

public XMLDecoder (InputStream in, Object owner)

Creates a new input stream for reading archives created by the XMLEncoder class.

Creates a new input stream for reading archives
created by the XMLEncoder class.
Parameters:
- in - The underlying stream.
- owner - The owner of this stream.

public XMLDecoder (InputStream in, Object owner, ExceptionListener exceptionListener)

Creates a new input stream for reading archives created by the XMLEncoder class.

Creates a new input stream for reading archives
created by the XMLEncoder class.
Parameters:
- in - the underlying stream.
- owner - the owner of this stream.
- exceptionListener - the exception handler for the stream; if null the default exception listener will be used.

public XMLDecoder (InputStream in, Object owner, ExceptionListener exceptionListener, ClassLoader cl)

Creates a new input stream for reading archives created by the XMLEncoder class.

Creates a new input stream for reading archives
created by the XMLEncoder class.
Parameters:
- in - the underlying stream. null may be passed without error, though the resulting XMLDecoder will be useless
- owner - the owner of this stream. null is a legal value
- exceptionListener - the exception handler for the stream, or null to use the default
- cl - the class loader used for instantiating objects. null indicates that the default class loader should be used
