y.layout.tree
Class BusPlacer

java.lang.Object
  y.layout.tree.AbstractRotatableNodePlacer
      y.layout.tree.BusPlacer

All Implemented Interfaces:

NodePlacer

public class BusPlacer
extends AbstractRotatableNodePlacer

The BusPlacer is a special NodePlacer that creates a bus where all child nodes and the root node are connected to.
The BusPlacer is rotatable using the constructor BusPlacer(AbstractRotatableNodePlacer.Matrix).

Constructor Detail

BusPlacer

public BusPlacer()

Initializes a new instance with the Default matrix.

BusPlacer

public BusPlacer(AbstractRotatableNodePlacer.Matrix modificationMatrix)

Initializes a new BusPlacer with the given modification matrix.

Parameters:

modificationMatrix -

Method Detail

determineChildConnector

protected byte determineChildConnector(Node child)

Description copied from class: AbstractRotatableNodePlacer

This method must be implemented by subclasses. It is used to assigns a connector shape direction to each child.

Specified by:

determineChildConnector in class AbstractRotatableNodePlacer

Parameters:

child -

Returns:

NodePlacer.DIRECTION_SOUTH

determineChildConnectors

public void determineChildConnectors(Node localRoot,
                                     DataMap connectorMap)

This method initializes internal data structures, then uses the abstract method determineChildConnector(y.base.Node) to determine the child node connector directions.

Specified by:

determineChildConnectors in interface NodePlacer

Overrides:

determineChildConnectors in class AbstractRotatableNodePlacer

Parameters:

localRoot - the local root node

connectorMap - the map that will be used to store the values

determineChildConnector(y.base.Node)

placeSubtree

protected y.layout.tree.SubtreeShapeRotated placeSubtree(Node localRoot,
                                                         byte parentConnectorDirection)

Places the root node and its children

Specified by:

placeSubtree in class AbstractRotatableNodePlacer

Parameters:

localRoot -

parentConnectorDirection -

Returns:

the created subtree shape

createComparator

public Comparator createComparator()

Overrides:

createComparator in class AbstractRotatableNodePlacer
