|
|
* **3.11.0 BACK COMPAT NOTE FOR COMPONENT DEVELOPERS**
|
|
*
|
|
* Prior to version 3.11.0, ATTRS would get added a class at a time. That is:
|
|
*
|
|
* <pre>
|
|
* for each (class in the hierarchy) {
|
|
* Call the class Extension constructors.
|
|
*
|
|
* Add the class ATTRS.
|
|
*
|
|
* Call the class initializer
|
|
* Call the class Extension initializers.
|
|
* }
|
|
* </pre>
|
|
*
|
|
* As of 3.11.0, ATTRS from all classes in the hierarchy are added in one `addAttrs` call
|
|
* before **any** initializers are called. That is, the flow becomes:
|
|
*
|
|
* <pre>
|
|
* for each (class in the hierarchy) {
|
|
* Call the class Extension constructors.
|
|
* }
|
|
*
|
|
* Add ATTRS for all classes
|
|
*
|
|
* for each (class in the hierarchy) {
|
|
* Call the class initializer.
|
|
* Call the class Extension initializers.
|
|
* }
|
|
* </pre>
|
|
*
|
|
* Adding all ATTRS at once fixes subtle edge-case issues with subclass ATTRS overriding
|
|
* superclass `setter`, `getter` or `valueFn` definitions and being unable to get/set attributes
|
|
* defined by the subclass. It also leaves us with a cleaner order of operation flow moving
|
|
* forward.
|
|
*
|
|
* However, it may require component developers to upgrade their components, for the following
|
|
* scenarios:
|
|
*
|
|
* 1. It impacts components which may have `setter`, `getter` or `valueFn` code which
|
|
* expects a superclass' initializer to have run.
|
|
*
|
|
* This is expected to be rare, but to support it, Base now supports a `_preAddAttrs()`, method
|
|
* hook (same signature as `addAttrs`). Components can implement this method on their prototype
|
|
* for edge cases which do require finer control over the order in which attributes are added
|
|
* (see widget-htmlparser for example).
|
|
*
|
|
* 2. Extension developers may need to move code from Extension constructors to `initializer`s
|
|
*
|
|
* Older extensions, which were written before `initializer` support was added, had a lot of
|
|
* initialization code in their constructors. For example, code which acccessed superclass
|
|
* attributes. With the new flow this code would not be able to see attributes. The recommendation
|
|
* is to move this initialization code to an `initializer` on the Extension, which was the
|
|
* recommendation for anything created after `initializer` support for Extensions was added.
|
|
*
|
|
* @class BaseCore

* @constructor

|
* @uses AttributeCore

* @param {Object} cfg Object with configuration property name/value pairs.

* The object can be used to provide initial values for the objects published
|
|
