Interface IPeLayoutService

All Known Subinterfaces:

ILayoutService, IPeService, IUiLayoutService

public interface IPeLayoutService

The interface IPeLayoutService provides services (e.g. query location info for a pictogram element) which makes it easier to write layout features.

Method Summary

ILocation	getConnectionMidpoint(Connection c, double d) Gets the connection midpoint.
IRectangle	getGaBoundsForAnchor(Anchor anchor) Returns the bounds of the graphics algorithm, which is referenced by the anchor.
ILocationInfo	getLocationInfo(Shape shape, int x, int y) Returns the location info for a specific position inside a shape.
ILocation	getLocationRelativeToDiagram(Anchor anchor) Returns the location of the anchor relative to the diagram.
ILocation	getLocationRelativeToDiagram(Shape shape) Returns the location of the shape relative to the diagram.

Method Detail

getConnectionMidpoint

ILocation getConnectionMidpoint(Connection c,
                                double d)

Gets the connection midpoint.

Parameters:

c - the connection

d - a relative location on the connection (must be between 0 and 1)

Returns:

the connection midpoint

getGaBoundsForAnchor

IRectangle getGaBoundsForAnchor(Anchor anchor)

Returns the bounds of the graphics algorithm, which is referenced by the anchor.

Parameters:

anchor - the anchor

Returns:

the bounds of the anchor graphics algorithm

getLocationInfo

ILocationInfo getLocationInfo(Shape shape,
                              int x,
                              int y)

Returns the location info for a specific position inside a shape. The location info contains the shape and the graphics algorithm at the given position.

Parameters:

shape - the shape

x - x coordinate

y - y coordinate

Returns:

the location info
