Class IlvGanttCycleSelectAccelerator.GraphicComparator

java.lang.Object

ilog.views.gantt.graphic.interactor.IlvGanttCycleSelectAccelerator.GraphicComparator

All Implemented Interfaces:

Comparator<IlvGraphic>

Enclosing class:

IlvGanttCycleSelectAccelerator

public static class IlvGanttCycleSelectAccelerator.GraphicComparator
extends Object
implements Comparator<IlvGraphic>

GraphicComparator defines the default selection traversal ordering across the objects in an IlvGanttSheet:

• The ordering among activity and reservation graphics is:
  1. Graphics are first ordered by row number.
  2. Within a row, graphics are ordered by X position, then by Y.
• The ordering of all other graphic pairs is first by Y position, then by X. This allows constraint links to be traversed adjacent to the uppermost graphic to which they are connected.

Method Detail

compare

public int compare(IlvGraphic g1,
                   IlvGraphic g2)

Compares two graphic objects in order to determine their selection traversal ordering. This method returns a negative integer, zero, or a positive integer as the first graphic should be traversed before, equal to, or after the second graphic.

• The ordering among activity and reservation graphics is:
  1. Graphics are first ordered by row number.
  2. Within a row, graphics are ordered by X position, then by Y.
• The ordering of all other graphic pairs is first by Y position, then by X. This allows constraint links to be traversed adjacent to the uppermost graphic to which they are connected.

Specified by:

compare in interface Comparator<IlvGraphic>

Parameters:

g1 - The first graphic object to be compared.

g2 - The second graphic object to be compared.

Returns:

A negative integer, zero, or a positive integer as the first graphic should be traversed before, equal to, or after the second graphic.

compareYThenX

protected int compareYThenX(IlvGraphic g1,
                            IlvGraphic g2)

Compares two graphic objects in order to determine their selection traversal ordering. This method returns a negative integer, zero, or a positive integer as the first graphic should be traversed before, equal to, or after the second graphic. This method orders graphics first by Y position, then by X position.

Parameters:

g1 - The first graphic object to be compared.

g2 - The second graphic object to be compared.

Returns:

A negative integer, zero, or a positive integer as the first graphic should be traversed before, equal to, or after the second graphic.

compareXThenY

protected int compareXThenY(IlvGraphic g1,
                            IlvGraphic g2)

Compares two graphic objects in order to determine their selection traversal ordering. This method returns a negative integer, zero, or a positive integer as the first graphic should be traversed before, equal to, or after the second graphic. This method orders graphics first by X position, then by Y position.

Parameters:

g1 - The first graphic object to be compared.

g2 - The second graphic object to be compared.

Returns:

A negative integer, zero, or a positive integer as the first graphic should be traversed before, equal to, or after the second graphic.

compareActivityGraphics

protected int compareActivityGraphics(IlvActivityGraphic ag1,
                                      IlvActivityGraphic ag2)

Compares two activity graphic objects in order to determine their selection traversal ordering. This method returns a negative integer, zero, or a positive integer as the first graphic should be traversed before, equal to, or after the second graphic. This method orders activity graphics first by row number. Within a row, activity graphics are ordered by X position, then by Y.

Parameters:

ag1 - The first activity graphic object to be compared.

ag2 - The second activity graphic object to be compared.

Returns:

A negative integer, zero, or a positive integer as the first graphic should be traversed before, equal to, or after the second graphic.
