Constructor Detail

InputRepresentation

public InputRepresentation(InputStream inputStream)

Constructor.

Parameters:

inputStream - The representation's stream.

InputRepresentation

public InputRepresentation(InputStream inputStream,
                           MediaType mediaType)

Constructor.

Parameters:

inputStream - The representation's stream.

mediaType - The representation's media type.

InputRepresentation

public InputRepresentation(InputStream inputStream,
                           MediaType mediaType,
                           long expectedSize)

Constructor.

Parameters:

inputStream - The representation's stream.

mediaType - The representation's media type.

expectedSize - The expected input stream size.

Method Detail

getStream

public InputStream getStream()
                      throws 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:

IOException

getText

public String getText()
               throws IOException

Note that this method relies on getStream(). This stream is closed once fully read.

Overrides:

getText in class Representation

Returns:

The representation as a string value.

Throws:

IOException

release

public void release()

Closes and releases the input stream.

Overrides:

release in class Representation

setStream

public void setStream(InputStream stream)

Sets the input stream to use.

Parameters:

stream - The input stream to use.

write

public void write(OutputStream outputStream)
           throws 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:

IOException
