Style implementation for INode instances in an IGraph.

Remarks

Implementations are responsible for rendering INode instances in a CanvasComponent. It is up to the implementation to interpret the visual appearance of a node. The framework uses the associated, possibly shared renderer to perform the actual rendering of this style for a given node. This interface extends the ICloneable interface. This allows clients to obtain a persistent copy of the current state of this style. Immutable style implementations may return themselves.

Working with styles (and their style renderers) is explained in detail in the section Visualization of Graph Elements: Styles.

Properties

renderer

: INodeStyleRenderer
readonlyabstract
Gets the renderer implementation that can be queried for implementations that provide details about the visual appearance and visual behavior for a given node and this style instance.
The idiom for retrieving, e.g. an IVisualCreator implementation for a given style is:
const creator = style.renderer.getVisualCreator(node, style)
const visual = creator.createVisual(context)
