Class OperationModule

Direct Known Subclasses:

DrawableOperationModule, ImageOperationModule, ShapeOperationModule, TextOperationModule

public abstract class OperationModule

extends java.lang.Object

The base class for an operation module. Operation modules can be either specific modules for a certain specialized type of content ("text/plain", for instance) or a module can be a generic handler for a certain group of content ("text/*").

While a generic handler may not be as performant as a specialized handler, that handler may be useful for displaying at least some of the content.

todo: add support for generic handlers to the operation factory.
