- // props: Object:

- // Add an instance-initialization function by making it a property

- // returns:

- // description:
- // Create a constructor using a compact notation for inheritance and
- // prototype extension.
- //
- // Mixin ancestors provide a type of multiple inheritance.
- // Prototypes of mixin ancestors are copied to the new class:
- // changes to mixin prototypes will not affect classes to which
- // they have been mixed in.
- //
- // Ancestors can be compound classes created by this version of
- // dojo.declare. In complex cases all base classes are going to be
- // linearized according to C3 MRO algorithm
- // (see http://www.python.org/download/releases/2.3/mro/ for more
- // details).
- //
- // "className" is cached in "declaredClass" property of the new class,
- // if it was supplied. The immediate super class will be cached in
- // "superclass" property of the new class.
- //
- // Methods in "props" will be copied and modified: "nom" property
- // (the declared name of the method) will be added to all copied
- // functions to help identify them for the internal machinery. Be
- // very careful, while reusing methods: if you use the same
- // function under different names, it can produce errors in some
- // cases.
- //
- // It is possible to use constructors created "manually" (without
- // dojo.declare) as bases. They will be called as usual during the
- // creation of an instance, their methods will be chained, and even
- // called by "this.inherited()".
- //
- // Special property "-chains-" governs how to chain methods. It is
- // a dictionary, which uses method names as keys, and hint strings
- // as values. If a hint string is "after", this method will be
- // called after methods of its base classes. If a hint string is
- // "before", this method will be called before methods of its base
- // classes.
- //
- // If "constructor" is not mentioned in "-chains-" property, it will
- // be chained using the legacy mode: using "after" chaining,
- // calling preamble() method before each constructor, if available,
- // and calling postscript() after all constructors were executed.
- // If the hint is "after", it is chained as a regular method, but
- // postscript() will be called after the chain of constructors.
- // "constructor" cannot be chained "before", but it allows
- // a special hint string: "manual", which means that constructors
- // are not going to be chained in any way, and programmer will call
- // them manually using this.inherited(). In the latter case
- // postscript() will be called after the construction.
- //
- // All chaining hints are "inherited" from base classes and
- // potentially can be overridden. Be very careful when overriding
- // hints! Make sure that all chained methods can work in a proposed
- // manner of chaining.
- //
- // Once a method was chained, it is impossible to unchain it. The
- // only exception is "constructor". You don't need to define a
- // method in order to supply a chaining hint.
- //
- // If a method is chained, it cannot use this.inherited() because
- // all other methods in the hierarchy will be called automatically.
- //
- // Usually constructors and initializers of any kind are chained
- // using "after" and destructors of any kind are chained as
- // "before". Note that chaining assumes that chained methods do not
- // return any value: any returned value will be discarded.
- //
- // example:
- // | dojo.declare("my.classes.bar", my.classes.foo, {
- // | // properties to be added to the class prototype
- // | someValue: 2,
- // | // initialization function
- // | constructor: function(){
- // | this.myComplicatedObject = new ReallyComplicatedObject();
- // | },
- // | // other functions
- // | someMethod: function(){
- // | doStuff();
- // | }
- // | });
- //
- // example:

- // | var MyClass1 = dojo.declare(MyBase, {

- // | var MyDiamond = dojo.declare([MyClass1, MyClass2], {

- // called.
- //
- // If "name" is not specified, it will be derived from the calling
- // method (using a methoid property "nom").

- // | var B = dojo.declare(A, {
