public abstract class JAIWriter extends Sink
Derived classes should have a postfire() method that creates a new _imageEncodeParameters, performs any setup on _imageEncodeParameters and then calls super.postfire()
The file is specified by the fileName attribute using any form acceptable to FileParameter.
If the confirmOverwrite parameter has value false, then this actor will overwrite the specified file if it exists without asking. If true (the default), then if the file exists, then this actor will ask for confirmation before overwriting.
