public boolean validateArguments(ServletContext sc,
                                 String cmd,
                                 Map<String,String> args,
                                 String[] urlElements)

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.

cmd - 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.

process

public void process(ServiceRegistry serviceRegistry,
                    HttpServletRequest request,
                    String commandName)

Description copied from interface: CommandProcessor

Process the supplied command name. It is the responsibility of the Command Processor to lookup the specified command name using the CommandFactory registry. For that reason it also has the responsiblity to initially register commands it is responsible for so they can be constructed later. If the supplied command is unknown to it then an exception should be thrown to indicate this.

Specified by:

process in interface CommandProcessor

Parameters:

serviceRegistry - ServiceRegistry

request - HttpServletRequest

commandName - Name of the command to construct and execute
