ParserService

This interface provides utility methods for parsing of commands for the administration of the framework.

Package com.prosyst.util.parser Description

This package provides the interface of the Parser Service. The Parser Service maintains a common set of commands so that bundles in the framework can retrieve these commands and redirect them to miscellaneous clients. Adding pluggable commands to this common set conveys capabilities for management and configuration of specific bundles and services.

The Parser Service manages an inventory of string commands, which a bundle developer may extend or may map to a specific communication stream. This service has two usage aspects:

• It allows you to extend the content of the command inventory by defining pluggable commands. Pluggable commands can be realized by any bundle wishing to export some of its functionality or internal information to its console clients (for example, the ProSyst Util Bundle provides a number of commands controlling the bundles and listing information; HTTP Bundle lists the aliases registered in the HttpService, etc.)

You can access a command also by its shortcut. A pluggable commands set is responsible for the execution of the commands it records in the Parser Service. In addition, it may organize its commands in a separate group.

To make the Parser Service recognize a pluggable commands entry, register it as a service in the OSGi framework.

• It allows you to obtain its currently stored commands and map their execution to client applications (Client) that use a specified communication output - such as local output, Telnet, etc.

1. When the end user issues a command (client input), the command receiver redirects it to the Parser Service (received command).
2. The Parser Service calls the pluggable commands entry that plugged the command, which executes it according to the client input.
3. The Parser Service sends the result from the execution to the client via the specified communication stream.
