base Module
yui3/src/base/js/BaseObservable.js:19
The base module provides the Base class, which objects requiring attribute and custom event support can extend. The module also provides two ways to reuse code - It augments Base with the Plugin.Host interface which provides plugin support and also provides the BaseCore.build method which provides a way to build custom classes using extensions.
This module provides the following classes:
This module is a rollup of the following modules:
-
base-base
The base-base submodule provides the Base class without the Plugin support, provided by Plugin.Host, and without the extension support provided by BaseCore.build.
-
base-build
The base-build submodule provides Base.build functionality, which can be used to create custom classes, by aggregating extensions onto a main class.
-
base-core
The base-core module provides the BaseCore class, the lightest version of Base, which provides Base's basic lifecycle management and ATTRS construction support, but doesn't fire init/destroy or attribute change events.
It mixes in AttributeCore, which is the lightest version of Attribute
-
base-observable
The
base-observable
submodule adds observability to Base's lifecycle and attributes, and also make it anEventTarget
. -
base-pluginhost
The base-pluginhost submodule adds Plugin support to Base, by augmenting Base with Plugin.Host and setting up static (class level) Base.plug and Base.unplug methods.
