  • Method Details

    • getReader

      public Reader getReader() throws IOException
      Description copied from class: Representation
      Returns a character 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:
      IOException

    • 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
      Description copied from class: Representation
      Converts the representation to a string value. Be careful when using this method as the conversion of large content to a string fully stored in memory can result in OutOfMemoryErrors being thrown.
      Overrides:
      getText in class Representation
      Returns:
      The representation as a string value.
      Throws:
      IOException

    • write

      public void write(Writer writer) throws 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:
      IOException

    • 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
