Class AbstractRotatableNodePlacer.RootAlignment

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

Enclosing class:

AbstractRotatableNodePlacer

public abstract static class AbstractRotatableNodePlacer.RootAlignment
extends Object

This class represents the horizontal alignment of the root node. There are several implementation that may be used:

• CENTER: Placement in the center
• CENTER_OVER_CHILDREN: Placement in the center of the direct children
• LEADING: Placement on the left of the children.
• TRAILING: Placement on the right of the children
• LEFT: Left alignment of root and children
• RIGHT: Right alignment of root and children

Field Summary

static AbstractRotatableNodePlacer.RootAlignment[]	ALL
static AbstractRotatableNodePlacer.RootAlignment	CENTER Horizontal alignment at the center.
static AbstractRotatableNodePlacer.RootAlignment	CENTER_OVER_CHILDREN Horizontal alignment at the center.
static AbstractRotatableNodePlacer.RootAlignment	LEADING Horizontal alignment at the left side of the children
static AbstractRotatableNodePlacer.RootAlignment	LEFT Horizontal alignment at the left.
static AbstractRotatableNodePlacer.RootAlignment	MEDIAN Horizontal alignment at the median.
static AbstractRotatableNodePlacer.RootAlignment	RIGHT Horizontal alignment at the right.
static AbstractRotatableNodePlacer.RootAlignment	TRAILING Horizontal alignment at the right side of the children.

Method Detail

placeParentHorizontal

protected abstract void placeParentHorizontal(y.layout.tree.SubtreeShapeRotated rootShape,
                                              List shapes,
                                              Rectangle2D shapeBounds,
                                              double spacing)

This method moves the rootShape to the right position relative to the children's shapes. The movement should only be done on the X-axis (horizontally).

Parameters:

rootShape - the shape of the root node that is moved

shapes - list of shapes of the children nodes

shapeBounds - accumulated shapes of all children's shapes

spacing - the spacing that should be used.

getBounds

protected static Rectangle2D getBounds(List shapes)

Calculates the bounds of a list of shapes.

Parameters:

shapes - the list of shapes the bounds shall be calculated of.

Returns:

the bounds around all shapes in the list.
