Method Detail

getStatus

public Status getStatus()

getKeyHandler

public KeyHandler getKeyHandler()

Description copied from interface: ShellProcess

Returns the key handler or null if the process won't handle key events.

Specified by:

getKeyHandler in interface ShellProcess

Returns:

the key handler for this process

execute

public void execute(ShellProcessContext processContext)

Description copied from interface: ShellProcess

Begin the process. The client of this method should make no assumption whether the process is executed in a synchronous or asynchronous manner. The process will be termined when the process signals it with an invocation of the ShellProcessContext.end(ShellResponse) method.

Specified by:

execute in interface ShellProcess

Parameters:

processContext - the process context

cancel

public void cancel()

Description copied from interface: ShellProcess

Signals the process it should be cancelled. This method cannot be be called before the process has started, it can be called multiple times after the process has started. The cancellation of the process is asynchronous, the cancellation of the process will terminate the current context lifecycle by calling the ShellProcessContext.end(ShellResponse) method.

Specified by:

cancel in interface ShellProcess
