Class Summary | |
---|---|
Command | The Command interface defines the interface of all command
objects. |
CommandProcessor | The CommandProcessor is responsible for managing the execution of the IDE commands and maintining the undo stack. |
Context | The Context class provides information about the state of the IDE when a command is in the process of being executed. |
Controller | Controllers encapulate extension defined UpdateHandler s and
InvokeHandler s. |
Command execution classes. These include classes such as the
Controller
that gets called when an action is
triggered by the user, and the command processing classes managing the
undo/redo stack.
IDE service providers must provide an implementation of the
CommandProcessor
. This class is responsible for
managing the execution of Command
s, and for
maintaining the undo stack.
When extension writers add new menus to an IDE, they must implement
the Controller
interface and declare their controller
implementation in the actions section of the Extension Deployment
Descriptor (EDD).
When one of these new menus is executed by the user, the IDE calls the
Controller
's handleAction
method. There,
the extension writers should instantiate the Command
implementation that will carry out some action, and use the
CommandProcessor
to invoke that command.
