Interface IBend

All Superinterfaces:

ILookup, IModelItem, ITagOwner

All Known Implementing Classes:

SimpleBend

public interface IBend
extends IModelItem

The interface used in an IGraph implementation to control the layout of edges.

This interface provides read-only access to the properties of a bend. In order to modify the state of an instance use the various methods provided by the IGraph this instance belongs to. Bends are stored in IListEnumerables, that can be obtained from the IEdge implementation that owns this bend. Like all items in an IGraph, this item supports the ILookup.lookup(java.lang.Class) method that can be used to query additional aspects of the item.

The graph model with all relevant types and their relationships is presented in detail in the section The Graph Model.

Using the look-up mechanism is explained in the section Service Locator Pattern: Lookup.

Some useful static methods can be found in GraphExtensions.

Method Detail

getIndex

default int getIndex()

Gets the index of the bend at its Owner.

Returns:

The zero based index of the bend in the Bends list; -1 if the bend is not part of an edge.

getLocation

IPoint getLocation()

Gets a view of the location of the bend in the world coordinate system.

The X and Y properties describe the location of the bend in the world coordinate system. This property is a live view of the location and will be updated in the future if the location changes. To keep the current state of the location, callers need to create a copy of it

Returns:

The Location.

IPoint.toPointD()

getOwner

IEdge getOwner()

Returns the edge this bend instance belongs to.

This implies that Owner.Bends contains this instance.

Returns:

The Owner.
