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:

Should not be reached, throws IllegalStateException

placeSubtree

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

Places the shapes of the children on the left and right side of a vertical bus.

Specified by:

placeSubtree in class AbstractRotatableNodePlacer

Parameters:

localRoot -

parentConnectorDirection -

Returns:

the new subtree shape

isPlaceLastOnBottom

public boolean isPlaceLastOnBottom()

Whether the last child is placed at the bottom of the other.

Returns:

whether the last child is placed at the bottom of the other.

setPlaceLastOnBottom

public void setPlaceLastOnBottom(boolean placeLastOnBottom)

Sets whether the last child is placed at the bottom of the other.

Parameters:

placeLastOnBottom - true if enabled, otherwise false

createComparator

public Comparator createComparator()
