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

getReader

public java.io.Reader getReader()
                         throws java.io.IOException

Description copied from class: Representation

Returns a characters reader with the representation's content. This method is ensured to return a fresh reader for each invocation unless it is a transient representation, in which case null is returned. If the representation has no character set defined, the system's default one will be used.

Specified by:

getReader in class Representation

Returns:

A reader with the representation's content.

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

write

public void write(java.io.Writer writer)
           throws java.io.IOException

Description copied from class: Representation

Writes the representation to a characters writer. 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 Writer after writing to it as this will be handled by the Restlet connectors automatically.

Specified by:

write in class Representation

Parameters:

writer - The characters writer.

Throws:

java.io.IOException
