Component

abstract class Component implements IComponent

Component is the base class for all components.

Components are objects implementing IComponent. They has parent component and own name.

Properties

string read-only $name
IContainer|null read-only $parent

Methods

IComponent|null
lookup(string|null $type, bool $throw = true)

Finds the closest ancestor specified by class or interface name.

string|null
lookupPath(string|null $type = null, bool $throw = true)

Finds the closest ancestor specified by class or interface name and returns backtrace path.

void
monitor(string $type, callable|null $attached = null, callable|null $detached = null)

Starts monitoring of ancestors.

void
unmonitor(string $type)

Stops monitoring of ancestors.

void
attached(IComponent $obj) deprecated

This method will be called when the component (or component's parent) becomes attached to a monitored object. Do not call this method yourself.

void
detached(IComponent $obj) deprecated

This method will be called before the component (or component's parent) becomes detached from a monitored object. Do not call this method yourself.

string|null
getName()

No description

IContainer|null
getParent()

Returns the parent container if any.

IComponent
setParent(IContainer|null $parent, string|null $name = null)

Sets or removes the parent of this component. This method is managed by containers and should not be called by applications

void
validateParent(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

__clone()

Object cloning.

__sleep()

Prevents serialization.

__wakeup()

Prevents unserialization.
