Properties

$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

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.
