Methods summary
`public`	# `__construct( )`
`public Nette\ComponentModel\IComponent\|null`	# `lookup( string\|null $type, boolean $throw = true )` Finds the closest ancestor specified by class or interface name. Finds the closest ancestor specified by class or interface name. Parameters `$type` `$throw` Returns `Nette\ComponentModel\IComponent\|null` IComponent\|null
`public string\|null`	# `lookupPath( string\|null $type = null, boolean $throw = true )` Finds the closest ancestor specified by class or interface name and returns backtrace path. A path is the concatenation of component names separated by self::NAME_SEPARATOR. Finds the closest ancestor specified by class or interface name and returns backtrace path. A path is the concatenation of component names separated by self::NAME_SEPARATOR. Parameters `$type` `$throw` Returns `string\|null` string\|null
`final public`	# `monitor( string $type, callable $attached = null, callable $detached = null )` Starts monitoring of ancestors. Starts monitoring of ancestors. Parameters `$type` `$attached` `$detached`
`public`	# `unmonitor( string $type )` Stops monitoring of ancestors. Stops monitoring of ancestors. Parameters `$type`
`protected`	# `attached( Nette\ComponentModel\IComponent $obj )` This method will be called when the component (or component's parent) becomes attached to a monitored object. Do not call this method yourself. This method will be called when the component (or component's parent) becomes attached to a monitored object. Do not call this method yourself. Deprecated use monitor($type, $attached) Parameters `$obj`
`protected`	# `detached( Nette\ComponentModel\IComponent $obj )` This method will be called before the component (or component's parent) becomes detached from a monitored object. Do not call this method yourself. This method will be called before the component (or component's parent) becomes detached from a monitored object. Do not call this method yourself. Deprecated use monitor($type, null, $detached) Parameters `$obj`
`public string\|null`	# `getName( )` Returns `string\|null` string\|null Implementation of `Nette\ComponentModel\IComponent::getName()`
`public Nette\ComponentModel\IContainer\|null`	# `getParent( )` Returns the parent container if any. Returns the parent container if any. Returns `Nette\ComponentModel\IContainer\|null` IContainer\|null Implementation of `Nette\ComponentModel\IComponent::getParent()`
`public Nette\ComponentModel\Component`	# `setParent( Nette\ComponentModel\IContainer $parent = null, $name = null )` Sets or removes the parent of this component. This method is managed by containers and should not be called by applications Sets or removes the parent of this component. This method is managed by containers and should not be called by applications Parameters `$parent` $name `$name` Returns `Nette\ComponentModel\Component` static Throws `Nette\InvalidStateException` Nette\InvalidStateException Internal Implementation of `Nette\ComponentModel\IComponent::setParent()`
`protected`	# `validateParent( Nette\ComponentModel\IContainer $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 Nette\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 Nette\InvalidStateException Throws `Nette\InvalidStateException` Nette\InvalidStateException
`public`	# `__clone( )` Object cloning. Object cloning.
`public`	# `__sleep( )` Prevents serialization. Prevents serialization.
`public`	# `__wakeup( )` Prevents unserialization. Prevents unserialization.
