Class BaseNodeCommandProcessor

java.lang.Object

org.alfresco.web.app.servlet.command.BaseNodeCommandProcessor

All Implemented Interfaces:

CommandProcessor

Direct Known Subclasses:

WorkflowCommandProcessor

public abstract class BaseNodeCommandProcessor
extends Object
implements CommandProcessor

Initial implementation of a Command Processor that is always passed enough URL elements to construct a single NodeRef argument. The NodeRef is checked against READ permissions for the current user during the validateArguments() call.

This class should be enough to form the base of Command Processor objects that only require a single NodeRef passed on the URL.

Description copied from interface: CommandProcessor

Pass and validate URL arguments for the command processor. Validate if the command can be executed given the arguments supplied. Generally at this post a Command Processor will convert the supplied arguments to the objects it expects, and also check any permissions that are required by the current user to execute the command.

Specified by:

validateArguments in interface CommandProcessor

Parameters:

sc - ServletContext, can be used to retrieve ServiceRegistry instance from the Repository bean.

command - Name of the command the arguments are for

args - Map of URL args passed to the command servlet

urlElements - String[] of the remaining URL arguments to the command servlet

Returns:

true if the command can be executed by the current user given the supplied args.
