StretchNodeLabelProcessingStep

Show Usages

A class responsible for calculating the location and size of a Shape representing an ILabel object which is being placed based on the StretchNodeLabelModel.

Remarks

More precisely, this class calculates the width/height of the label's shape and its location based on the ILabelModelParameter that has been used from the StretchNodeLabelModel.

This processing step has to be registered to the list of IShapeProcessingSteps of the VsdxExportConfiguration and needs to run after NodeLayoutProcessingStep.

shape: Shape
sourceConnection: Connection
targetConnection: Connection
edge: IEdge
context: ShapeProcessingContext
): Promise<void>

See node.

Parameters

shape: Shape

The shape representing the edge.

sourceConnection: Connection

The source connection representing the source port.

targetConnection: Connection

The target connection representing the target port.

edge: IEdge

The edge this shape represents.

context: ShapeProcessingContext

Return Value

Promise<void>
An empty promise.

label

(

ownerShape: Shape
label: ILabel
context: ShapeProcessingContext
): Promise<void>

See node.

Parameters

shape: Shape

The shape representing the label.

ownerShape: Shape

The shape representing the label's owner. In case the owner is a node, this is the container shape of the node.

label: ILabel

The label this shape represents

shape: Shape
ownerShape: GroupShape
port: IPort
context: ShapeProcessingContext
): Promise<void>

See node.

Parameters

shape: Shape

The shape representing the port.

ownerShape: GroupShape

The shape representing the port's owner. In case the owner is a node, this is the container shape of the node.

port: IPort

The port this shape represents.

context: ShapeProcessingContext

Return Value

Promise<void>
An empty promise.
