Methods summary
`public`	# `__construct( IComponentContainer $parent = NULL, $name = NULL )`
`public NPresenter\|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 `NPresenter\|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( 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` `IComponent`
`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 NPresenterComponentReflection`	# `getReflection( )` Access to reflection. Access to reflection. Returns `NPresenterComponentReflection`
`public`	# `loadState( array $params )` Loads state informations. Loads state informations. Parameters `$params` `array` Implementation of `IStatePersistent::loadState`
`public`	# `saveState( array & $params, NPresenterComponentReflection $reflection = NULL )` Saves state informations for next request. Saves state informations for next request. Parameters `$params` `array` `$reflection` `NPresenterComponentReflection` (internal, used by Presenter) Implementation of `IStatePersistent::saveState`
`final public mixed`	# `getParam( string $name = NULL, mixed $default = NULL )` Returns component param. If no key is passed, returns the entire array. Returns component param. If no key is passed, returns the entire array. Parameters `$name` `string` key `$default` `mixed` default value Returns `mixed`
`final public string`	# `getParamId( $name )` Returns a fully-qualified name that uniquely identifies the parameter. Returns a fully-qualified name that uniquely identifies the parameter. Returns `string`
`public static array`	# `getPersistentParams( )` Returns array of classes persistent parameters. They have public visibility and are non-static. This default implementation detects persistent parameters by annotation @persistent. Returns array of classes persistent parameters. They have public visibility and are non-static. This default implementation detects persistent parameters by annotation @persistent. Returns `array`
`public`	# `signalReceived( string $signal )` Calls signal handler method. Calls signal handler method. Parameters `$signal` `string` Throws `NBadSignalException` if there is not handler method Implementation of `ISignalReceiver::signalReceived`
`public string`	# `formatSignalMethod( string $signal )` Formats signal handler method name -> case sensitivity doesn't matter. Formats signal handler method name -> case sensitivity doesn't matter. Parameters `$signal` `string` Returns `string`
`public string`	# `link( string $destination, array\|mixed $args = array() )` Generates URL to presenter, action or signal. Generates URL to presenter, action or signal. Parameters `$destination` `string` destination in format "[[module:]presenter:]action" or "signal!" or "this" `$args` `array\|mixed` Returns `string` Throws `NInvalidLinkException`
`public NLink`	# `lazyLink( string $destination, array\|mixed $args = array() )` Returns destination as Link object. Returns destination as Link object. Parameters `$destination` `string` destination in format "[[module:]presenter:]view" or "signal!" `$args` `array\|mixed` Returns `NLink`

`final public`	# `offsetSet( string $name, IComponent $component )` Adds the component to the container. Adds the component to the container. Parameters `$name` `string` component name `$component` `IComponent` Implementation of `ArrayAccess::offsetSet`
`final public IComponent`	# `offsetGet( string $name )` Returns component specified by name. Throws exception if component doesn't exist. Returns component specified by name. Throws exception if component doesn't exist. Parameters `$name` `string` component name Returns `IComponent` Throws `InvalidArgumentException` Implementation of `ArrayAccess::offsetGet`
`final public boolean`	# `offsetExists( string $name )` Does component specified by name exists? Does component specified by name exists? Parameters `$name` `string` component name Returns `boolean` Implementation of `ArrayAccess::offsetExists`
`final public`	# `offsetUnset( string $name )` Removes component from the container. Removes component from the container. Parameters `$name` `string` component name Implementation of `ArrayAccess::offsetUnset`
