SimpleBend

Show Usages
A mutable implementation of the IBend interface that can be used without an IGraph.
ImplementsInheritance Hierarchy

Remarks

Note that this class is not the one used as the default implementation of a Graph's IBends and casting them to SimpleBend will fail. Instances of this class can be used without an accompanying graph instance. All the properties are mutable. An example of a possible use case would be the rendering of a SimpleEdge with bends into a graphics context: Simply create two SimpleNodes, a SimpleEdge to connect the two nodes and add instances of this class to the edge's bends model. Then render the edge.

Constructors

SimpleBend

(owner?: IEdge, location?: IPoint)
Initializes a new instance of the SimpleBend class using the given owner and location.

Parameters

owner?: IEdge
The owner of the bend.
location?: IPoint
The bend's location. By default, the bend is placed at ORIGIN.

IBend.index

location

: IPoint
Gets or sets the location of this bend.

Implements

IBend.location

owner

: IEdge
Gets or sets the edge this bend instance belongs to.

Implements

IBend.owner

tag

: IBend['tag']
Gets or sets the tag object associated with this item instance.
The tag is an optional user-defined object which can be used to store arbitrary data related to this item. The item itself just provides the storage for the object.

Methods

getDecorator

(): BendDecorator
Gets a BendDecorator to modify the ports ILookup.
final

Return Value

BendDecorator
A BendDecorator for this instance.

lookup

<T> (type: Constructor<T>): T
Returns an instance that implements the given type or null.
Typically, this method will be called to obtain a different view or aspect of the current instance. This is quite similar to casting or using a super type or interface of this instance, but is not limited to inheritance or compile-time constraints. An instance implementing this method is not required to return non-null implementations for the types, nor does it have to return the same instance any time. Also, it depends on the type and context whether the instance returned stays up to date or needs to be re-obtained for further use.
final

Parameters

type: Constructor<T>
the type for which an instance shall be returned

Return Value

T
an instance that is assignable to the type or null
