Method Detail

createSession

public CommandSession createSession(java.io.InputStream in,
                                    java.io.PrintStream out,
                                    java.io.PrintStream err)

Description copied from interface: CommandProcessor

Create a new command session associated with IO streams.

The session is bound to the life cycle of the bundle getting this service. The session will be automatically closed when this bundle is stopped or the service is returned.

The shell will provide any available commands to this session and can set additional variables.

Specified by:

createSession in interface CommandProcessor

Parameters:

in - The value used for System.in

out - The stream used for System.out

err - The stream used for System.err

Returns:

A new session.
