Class PluginCollection
Plugin Collection
Holds onto plugin objects loaded into an application, and provides methods for iterating, and finding plugins based on criteria.
This class implements the Iterator interface to allow plugins to be iterated, handling the situation where a plugin's hook method (usually bootstrap) loads another plugin during iteration.
While its implementation supported nested iteration it does not
support using continue or break inside loops.

add(Cake\Core\PluginInterface $plugin): $thisAdd a plugin to the collection
Plugins will be keyed by their names.
Parameters
-
Cake\Core\PluginInterface$plugin The plugin to load.

$thiscount() ¶ public
count(): intImplementation of Countable.
Get the number of plugins in the collection.

Cake\Core\PluginInterfacefindPath() ¶ public
findPath(string $name): stringLocate a plugin path by looking at configuration data.
This will use the plugins Configure key, and fallback to enumerating App::path('plugins')
This method is not part of the official public API as plugins with no plugin class are being phased out.

get() ¶ public
get(string $name): Cake\Core\PluginInterfaceGet the a plugin by name.
If a plugin isn't already loaded it will be autoloaded on first access and that plugins loaded this way may miss some hook methods.
Parameters

has() ¶ public
has(string $name): boolCheck whether the named plugin exists in the collection.

string$name The named plugin.
Returns
boolloadConfig() ¶ protected
