Constants

T_NOTIFIER

T_NOTIFIER = false

A notifier edge sends notification to its head node, following its creation.

T_SUBSCRIBER

T_SUBSCRIBER = false

A subscriber edge retrieves notification updates from its head.

T_CONSUMER

T_CONSUMER = true

A consumer edge returns its head node when the ```$edge->return()``` function is called. Otherwise, it returns the edge itself.

T_FORMATIVE

T_FORMATIVE = false

A formative edge creates new nodes.

Properties

$_methods

$_methods : array

methods that would be available in this class

Type

array

$binding

$binding : boolean

Holds the binding value.

In this generic implementation, it is set false. An edge with a binding predicate would have its head deleted when the edge itself is destroyed.

Type

boolean

$multiplicable

$multiplicable : boolean

Holds the multiplicable value.

In this generic implementation, it is set false. An edge with a multiplicable predicate can be created multiple times from a particular tail to a particular head.

Type

boolean

Methods

__construct()

__construct()

Constructor.

Warning: count(): Parameter must be an array or an object that implements Countable in phar:///Users/emresokullu/Code/website/phpdoc/vendor/twig/twig/lib/Twig/Extension/Core.php on line 1275 Warning: count(): Parameter must be an array or an object that implements Countable in phar:///Users/emresokullu/Code/website/phpdoc/vendor/twig/twig/lib/Twig/Extension/Core.php on line 1275

__call()

__call(\Pho\Framework\string  $name, array  $args)

{@internal}

Used to call predicate traits.

Parameters

\Pho\Framework\string	$name
array	$args

binding()

binding() : boolean

Checks if the predicate is binding.

If a predicate is binding, should the edge's tail node is deleted, not only the edge itself gets stripped off, but the head node must be removed as well.

Returns

boolean

multiplicable()

multiplicable() : boolean

Checks if the predicate is multiplicable.

If a predicate is multiplicable, its edge may be created multiple times between a particular tail and a particular head.

Returns

boolean

__toString()

__toString() : string

Returns the full class name

Returns

string

label()

label() : string

Returns the predicate in string format

Label is actually the short-form class name. For full class name, use (string) $predicate

Returns

string
