Plugin.Host Class

An augmentable class, which provides the augmented class with the ability to host plugins. It adds plug and unplug methods to the augmented class, which can be used to add or remove plugins from instances of the class.

Plugins can also be added through the constructor configuration object passed to the host class' constructor using the "plugins" property. Supported values for the "plugins" property are those defined by the plug method. For example the following code would add the AnimPlugin and IOPlugin to Overlay (the plugin host):

var o = new Overlay({plugins: [ AnimPlugin, {fn:IOPlugin, cfg:{section:"header"}}]});

Plug.Host's protected _initPlugins and _destroyPlugins methods should be invoked by the host class at the appropriate point in the host's lifecyle.

Methods

_destroyPlugins

() private

Unplugs and destroys all plugins on the host

_initConfigPlugins

(
  • config
)
protected

Provided by the pluginhost-config module.

Defined in pluginhost/js/PluginHostConfig.js:9

A protected initialization method, used by the host class to initialize plugin configurations passed the constructor, through the config object.

Host objects should invoke this method at the appropriate time in their construction lifecycle.

Parameters:

  • config Object

    The configuration object passed to the constructor

_initPlugins

(
  • config
)
private

Initializes static plugins registered on the host (using the Base.plug static method) and any plugins passed to the instance through the "plugins" configuration property.

Parameters:

  • config Object

    The configuration object with property name/value pairs.

hasPlugin

(
  • ns
)
Plugin

Determines if a plugin has plugged into this host.

Parameters:

  • ns String

    The plugin's namespace

Returns:

Plugin:

Returns a truthy value (the plugin instance) if present, or undefined if not.

plug

(
  • P
  • config
)
Base chainable

Adds a plugin to the host object. This will instantiate the plugin and attach it to the configured namespace on the host object.

Parameters:

  • P Function | Object | Array

    Accepts the plugin class, or an object with a "fn" property specifying the plugin class and a "cfg" property specifying the configuration for the Plugin.

    Additionally an Array can also be passed in, with the above function or object values, allowing the user to add multiple plugins in a single call.

  • config Object

    (Optional) If the first argument is the plugin class, the second argument can be the configuration for the plugin.

Returns:

Base:

A reference to the host object

plug

(
  • hostClass
  • plugin
  • config
)
static

Provided by the pluginhost-config module.

Defined in pluginhost/js/PluginHostConfig.js:60

Registers plugins to be instantiated at the class level (plugins which should be plugged into every instance of the class by default).

Parameters:

  • hostClass Function

    The host class on which to register the plugins

  • plugin Function | Array

    Either the plugin class, an array of plugin classes or an array of objects (with fn and cfg properties defined)

  • config Object

    (Optional) If plugin is the plugin class, the configuration for the plugin

unplug

(
  • plugin
)
Base chainable

Removes a plugin from the host object. This will destroy the plugin instance and delete the namespace from the host object.

Parameters:

    The namespace of the plugin, or the plugin class with the static NS namespace property defined. If not provided, all registered plugins are unplugged.

Returns:

Base:

A reference to the host object

(
  • hostClass
  • plugin
)
static
