Interface IntermediateLayout

All Known Implementing Classes:

AnimatableIntermediateLayout, DirectIntermediateLayout

public interface IntermediateLayout

An intermediate layout which can be used for animated graph drawing. The layout determines both the intermediate positions for nodes and edges to be drawn at.

Method Summary

Modifier and Type	Method and Description
IntermediateLayout	clone() Returns an uninitialized clone of this intermediate layout which can be used for further calculations.
boolean	hasNextLayout() Returns whether a next intermediate layout exists.
java.util.List<Position>	intermediatePositionsForEdge(Edge edge) The intermediate positions for the edge to be drawn at in the layout.
java.util.Optional<Position>	positionForNode(Node node) The position for the node in the intermediate layout.
void	prepareForNextLayout() Prepares this intermediate layout for the next layout step.

Method Detail

hasNextLayout

boolean hasNextLayout()

Returns whether a next intermediate layout exists.

Returns:

Returns whether a next intermediate layout exists.

prepareForNextLayout

void prepareForNextLayout()

Prepares this intermediate layout for the next layout step. Note that this method only has an effect if hasNextLayout returns true.

positionForNode

java.util.Optional<Position> positionForNode(Node node)

The position for the node in the intermediate layout. Returns an empty optional, if the node does not have a position set yet in the intermediate layout.

Parameters:

node - The node for which to get the intermediate position.

Returns:

The intermediate position of the node, or an empty Optional if none is set.

intermediatePositionsForEdge

java.util.List<Position> intermediatePositionsForEdge(Edge edge)

The intermediate positions for the edge to be drawn at in the layout. Returns an empty list, if any of the two endpoints of the edge do not yet have an intermediate position set.

Parameters:

edge - The edge for which to get the intermediate positions.

Returns:

The intermediate positions of the edge, or an empty list if either endpoint has no intermediate position.

clone

IntermediateLayout clone()

Returns an uninitialized clone of this intermediate layout which can be used for further calculations.

Returns:

An uninitialized clone of this intermediate layout.
