PresenterComponent is the base class for all Presenter components.

Components are persistent objects located on a presenter. They have ability to own other child components, and interact with user. Components have properties for storing their status, and responds to user command.

Methods summary
`public Nette\Application\UI\Presenter\|null`	# `getPresenter( boolean $need = TRUE )` Returns the presenter where this component belongs to. Returns the presenter where this component belongs to. Parameters `$need` `boolean` throw exception if presenter doesn't exist? Returns `Nette\Application\UI\Presenter\|null`
`public string`	# `getUniqueId( )` Returns a fully-qualified name that uniquely identifies the component within the presenter hierarchy. Returns a fully-qualified name that uniquely identifies the component within the presenter hierarchy. Returns `string`
`protected`	# `attached( Nette\ComponentModel\IComponent $presenter )` This method will be called when the component (or component's parent) becomes attached to a monitored object. Do not call this method yourself. This method will be called when the component (or component's parent) becomes attached to a monitored object. Do not call this method yourself. Parameters `$presenter` `Nette\ComponentModel\IComponent` Overrides `Nette\ComponentModel\Component::attached()`
`protected`	# `validateParent( Nette\ComponentModel\IContainer $parent )` Throws `Nette\InvalidStateException` Overrides `Nette\ComponentModel\Component::validateParent()`
`protected boolean`	# `tryCall( string $method, array $params )` Calls public method if exists. Calls public method if exists. Parameters `$method` `string` `$params` `array` Returns `boolean` does method exist?
`public`	# `checkRequirements( $element )` Checks for requirements such as authorization. Checks for requirements such as authorization.
