Method Summary

Modifier and Type	Method	Description
java.nio.channels.ReadableByteChannel	getChannel()	Returns a channel with the representation's content. If it is supported by a file, a read-only instance of FileChannel is returned. This method is ensured to return a fresh channel for each invocation unless it is a transient representation, in which case null is returned.
java.io.InputStream	getStream()	Returns a stream with the representation's content.
void	write(java.io.OutputStream outputStream)	Writes the representation to a byte stream.
void	write(java.nio.channels.WritableByteChannel writableChannel)	Writes the representation to a byte channel.

Method Detail

getChannel

public java.nio.channels.ReadableByteChannel getChannel()
                                                 throws java.io.IOException

Description copied from class: Representation

Returns a channel with the representation's content.
If it is supported by a file, a read-only instance of FileChannel is returned.
This method is ensured to return a fresh channel for each invocation unless it is a transient representation, in which case null is returned.

Specified by:

getChannel in class Representation

Returns:

A channel with the representation's content.

Throws:

java.io.IOException

getStream

public java.io.InputStream getStream()
                              throws java.io.IOException

Description copied from class: Representation

Returns a stream with the representation's content. This method is ensured to return a fresh stream for each invocation unless it is a transient representation, in which case null is returned.

Specified by:

getStream in class Representation

Returns:

A stream with the representation's content.

Throws:

java.io.IOException

write

public void write(java.io.OutputStream outputStream)
           throws java.io.IOException

Description copied from class: Representation

Writes the representation to a byte stream. This method is ensured to write the full content for each invocation unless it is a transient representation, in which case an exception is thrown.

Note that the class implementing this method shouldn't flush or close the given OutputStream after writing to it as this will be handled by the Restlet connectors automatically.

Specified by:

write in class Representation

Parameters:

outputStream - The output stream.

Throws:

java.io.IOException

write

public void write(java.nio.channels.WritableByteChannel writableChannel)
           throws java.io.IOException

Description copied from class: Representation

Writes the representation to a byte channel. This method is ensured to write the full content for each invocation unless it is a transient representation, in which case an exception is thrown.

Specified by:

write in class Representation

Parameters:

writableChannel - A writable byte channel.

Throws:

java.io.IOException
