API Reference

Utils.namespace

<Object namespace> Utils.namespace(<String namespace> [, extensions ])

namespace creates a new global namespace object. It takes a namespace argument which is a dot separated string containing the name of the namespace to be created eg. Utils.namespace("some.name.space"). If the named global object or any of the objects in the chain are not defined, it will create an empty object with that name i.e. if no objects are defined the above code is equivalent to var some = {}; some.name = {}; some.name.space = {};
Any additional arguments are passed to extend which is called with the namespace object as the source.

Utils.extend

<Object source> Utils.extend(<Object source>, extension [, extensions ])

extend takes a source argument which is the object to be extended, and at least one extension argument. If the extension argument is an Object then the properties of the extension are copied to the source argument. If the extension argument is a Function then the the function is called and the source is extended with the return value of the function. If the extension argument is an Array or there are more than one extension arguments, the source is extended with each of the elements in the array.

Utils.extend(someObject, function(){ // ... return { someFunction : function(){ /* ... */ } }; });

Utils.replaceNamespace

<Object namespace> Utils.replaceNamespace(<String namespace> [, extensions ])

replaceNamespace is a destructive version of namespace. replaceNamespace will replace the namespace object (but not it's predecessors in the chain) if it is already defined. replaceNamespace also records the original value of the namespace object, so that it can be recovered with revertNamespace.
Utils.replaceNamespace("SomeNamespace")

Utils.revertNamespace

<Object namespace> Utils.revertNamespace(<String namespace>)

revertNamespace allows the namespace to be renamed in case of conflict. This method only works if the namespace was initially created with replaceNamespace.
var NewNamespace = Utils.revertNamespace("SomeNamespace")

Utils.Extendable

<Extendable>.extend(extension [, extensions])

Extendable is a mixin object which adds extend abilities to any object.
Utils.extend(someObject, Utils.Extendable) someObject.extend({ someFunc : function(){} }

Utils.Namespaceable

<Namespaceable>.namespace(name [, extensions])

Namespaceable is a mixin object which adds namespace abilities to any object. Utils.namespace("SomeNamespace", Utils.Namespaceable) SomeNamespace.namespace("Utils")

Utils.Revertable

<Revertable>.revertNamespace()

Revertable is a mixin object which adds revertNamespace to a namespace object created with replaceNamespace. Utils.replaceNamespace("SomeNamespace", Utils.Revertable) var NewNamespace = SomeNamespace.revertNamespace()
