Methods summary
`public`	# `__construct( IComponentContainer $parent = NULL, $name = NULL )`
`public IComponent`	# `lookup( string $type, boolean $need = TRUE )` Lookup hierarchy for component specified by class or interface name. Lookup hierarchy for component specified by class or interface name. Parameters `$type` `string` class/interface type `$need` `boolean` throw exception if component doesn't exist? Returns `IComponent`
`public string`	# `lookupPath( string $type, boolean $need = TRUE )` Lookup for component specified by class or interface name. Returns backtrace path. A path is the concatenation of component names separated by self::NAME_SEPARATOR. Lookup for component specified by class or interface name. Returns backtrace path. A path is the concatenation of component names separated by self::NAME_SEPARATOR. Parameters `$type` `string` class/interface type `$need` `boolean` throw exception if component doesn't exist? Returns `string`
`public`	# `monitor( string $type )` Starts monitoring. Starts monitoring. Parameters `$type` `string` class/interface type
`public`	# `unmonitor( string $type )` Stops monitoring. Stops monitoring. Parameters `$type` `string` class/interface type
`protected`	# `attached( IComponent $obj )` This method will be called when the component (or component's parent) becomes attached to a monitored object. Do not call this method yourself. This method will be called when the component (or component's parent) becomes attached to a monitored object. Do not call this method yourself. Parameters `$obj` `IComponent`
`protected`	# `detached( IComponent $obj )` This method will be called before the component (or component's parent) becomes detached from a monitored object. Do not call this method yourself. This method will be called before the component (or component's parent) becomes detached from a monitored object. Do not call this method yourself. Parameters `$obj` `IComponent`
`final public string`	# `getName( )` Returns `string` Implementation of `IComponent::getName`
`final public IComponentContainer\|null`	# `getParent( )` Returns the container if any. Returns the container if any. Returns `IComponentContainer\|null` Implementation of `IComponent::getParent`
`public NComponent`	# `setParent( IComponentContainer $parent = NULL, string $name = NULL )` Sets the parent of this component. This method is managed by containers and should. not be called by applications Sets the parent of this component. This method is managed by containers and should. not be called by applications Parameters `$parent` `IComponentContainer` New parent or null if this component is being removed from a parent `$name` `string` Returns `NComponent` provides a fluent interface Throws `InvalidStateException` Implementation of `IComponent::setParent`
`protected`	# `validateParent( IComponentContainer $parent )` Is called by a component when it is about to be set new parent. Descendant can override this method to disallow a parent change by throwing an InvalidStateException Is called by a component when it is about to be set new parent. Descendant can override this method to disallow a parent change by throwing an InvalidStateException Parameters `$parent` `IComponentContainer` Throws `InvalidStateException`
`public`	# `__clone( )` Object cloning. Object cloning.
`final public`	# `__wakeup( )` Prevents unserialization. Prevents unserialization.
