Command

An abstract class used in implementing Mojo Commands. A Command is an object that encapsulates functionality for processing data and/or business logic.

Example

dojo.provide("sample.command.LoadHtmlCommand");
dojo.require("mojo.command.Command");
dojo.require("sample.service.Locator");

dojo.declare("sample.command.LoadHtmlCommand", mojo.command.Command,
function() {
},{
    execute: function(requestObj) {
        // invoke a service call to get some Html
        var locator = sample.service.Locator.getInstance();
        var service = locator.getService("getHtml")
        service.invoke(this.getRequest().getParams(), this);
    },
    onResponse: function(data) {
        // handle success response...
    },
    onError: function(error) {
        // handle error response...
    }
});

Summary

Command	An abstract class used in implementing Mojo Commands.
Functions
getRequest	Returns the mojo.controller.Request object passed into the Command.
execute	Abstract function that must be implemented in a concrete Command class.
onResponse	Abstract function that must be implemented in a concrete Command class.
onError	Abstract function that must be implemented in a concrete Command class.

getRequest

getRequest: function()

Returns the mojo.controller.Request object passed into the Command.

Returns

{object} Mojo Request Object

Example

//See above example implementation.

execute

execute: function( requestObj )

Abstract function that must be implemented in a concrete Command class. The Controller will automatically fire the execute() method when triggering a Command.

Parameters

requestObj

{object}

Example

//See above example implementation.

onResponse

onResponse: function( data )

Abstract function that must be implemented in a concrete Command class. Used to handle the data from a successful response.

Parameters

data

{object}

Exmaple

// see above for sample implementation usage.

onError

onError: function( error )

Abstract function that must be implemented in a concrete Command class. Used to handle errors from an error response.

Parameters

error

{object}

Example

//See above example implementation.
