BaseCommand

public BaseCommand()

Method Detail

getCommandHandler

public CommandHandler getCommandHandler()

The CommandHandler that will be called by this RPC Client to handle the execution of a Command. When execute() is called on this component it checks this property for a configured CommandHandler.

Specified by:

getCommandHandler in interface Command

Returns:

The CommandHandler

setCommandHandler

public void setCommandHandler(CommandHandler pCommandHandler)

Set the CommandHandler property.

Parameters:

pCommandHandler -

getContext

public java.util.Map getContext()

Contextual information that can be passed. By default, thiis class will not populate any information into this object. Applications can use this property as an extension point.

Specified by:

getContext in interface Command

Returns:

the context object

setContext

public void setContext(java.util.Map pContext)

Set the Conext property.

Parameters:

pContext -

doStartService

public void doStartService()
                    throws ServiceException

Description copied from class: GenericService

This is called after a Service has been created, placed into the naming hierarchy, and initialized with its configured property values. The Service should override this method to start any processes it requires.

Overrides:

doStartService in class GenericService

Throws:

ServiceException - if the Service had a problem starting up

execute

public CommandResult execute(java.lang.Object pInput)
                      throws CommandInvocationException,
                             CommandTimeoutException,
                             InvalidInputException

Application code should call this method to execute a RPC call

This method will check to see if there is a CommandHandler configured on this component and if so, will call the executeCommand() on that particular CommandHandler.

If no CommandHandler is configured then the invokeRPC(Object) method is called.

This method has PerformanceMonitor code associated with it. If the PerformanceMonitor is enabled, this method will generate statistics on how long it takes to execute the Command.

Specified by:

execute in interface Command

Parameters:

pInput - input object to pass to the command

Returns:

a CommandResult object

Throws:

CommandInvocationException - if an error occurs

CommandTimeoutException - if time expires for the command.

InvalidInputException - if input object passed is invalid.

invokeRPC

public abstract CommandResult invokeRPC(java.lang.Object pInput)
                                 throws CommandInvocationException,
                                        CommandTimeoutException,
                                        InvalidInputException

Abstract method. Classes that extend this class should override this method and provide an implementation that actually executes the RPC method that this Command backs.

Specified by:

invokeRPC in interface Command

Parameters:

pInput - object

Returns:

CommandResult object

Throws:

CommandInvocationException - if an error occurs

CommandTimeoutException - if time expires for the command.

InvalidInputException - if input object passed is invalid.
