Class IlpShapeFileBackground

java.lang.Object
  ilog.cpl.graphic.views.background.IlpShapeFileBackground

All Implemented Interfaces:

IlpBackground

Deprecated. See the Migration Guide a migration path.

public class IlpShapeFileBackground
extends Object
implements IlpBackground

Provides support for using ESRI .shp Shape files as background.

This background loader reads:

• the main shape file, with extension .shp.
• the attributes file, with extension .dbf (optional),
• for load-on-demand: the ESRI index file, with extension .shx, and the ILOG JViews spatial index file, with extension .idx (optional).

See also: the ILOG JViews demo demos/maps/esri, which can be used to create the spatial index (.idx) files, and the ILOG JViews package ilog.views.maps.format.shapefile.

The XML settable properties are:

property name="url" (required)

The URL of the .shp file. The other three files are expected to be located in the same directory.

property name="loadOnDemand" (optional)

True if the memory saving technique of load-on-demand is to be used.

Since:

JTGO 3.0

Deprecated Since:
