Class XmlOutputStream<T>

java.lang.Object
  java.io.OutputStream
      javolution.xml.XmlOutputStream<T>

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable, Reusable

public class XmlOutputStream<T>
extends java.io.OutputStream
implements Reusable

This class represents an object output stream using ObjectWriter for object serialization.

Instances of this class embed their own data buffer, wrapping using a java.io.BufferedOutputStream is therefore unnescessary.

Constructor Detail

XmlOutputStream

public XmlOutputStream()

Default constructor.

XmlOutputStream

public XmlOutputStream(ObjectWriter<T> writer)

Creates a xml output stream using the specified object writer.

Parameters:

writer - the object writer.

Method Detail

setOutputStream

public XmlOutputStream setOutputStream(java.io.OutputStream out)

Sets the underlying output destination for this stream.

Parameters:

out - the output destination.

Returns:

this

Throws:

java.lang.IllegalStateException - if this stream is being reused and it has not been closed or reset.

writeObject

public void writeObject(T obj)
                 throws java.io.IOException

Writes an object to the underlying stream using an ObjectWriter.

Parameters:

obj - the object writen using its xml representation.

Throws:

java.io.IOException - if an I/O error occurs.

write

public void write(int b)
           throws java.io.IOException

Writes the specified byte to this output stream

Specified by:

write in class java.io.OutputStream

Parameters:

b - the byte.

Throws:

java.io.IOException - if an I/O error occurs.

flush

public void flush()
           throws java.io.IOException

Flushes this output stream and forces any buffered output bytes to be written out.

Specified by:

flush in interface java.io.Flushable

Overrides:

flush in class java.io.OutputStream

Throws:

java.io.IOException - if an I/O error occurs.

write

                  int len)
           throws java.io.IOException

Writes the specified number of bytes from the specified byte array starting at the specified offset to this output stream.

Overrides:

write in class java.io.OutputStream

Parameters:

b - the data.

off - the start offset in the data.

len - the number of bytes to write.

Throws:

java.io.IOException - if an I/O error occurs.

close

public void close()
           throws java.io.IOException

Closes and resets this stream for reuse.

Specified by:

close in interface java.io.Closeable

Overrides:

close in class java.io.OutputStream

Throws:

java.io.IOException - if an I/O error occurs.
