Class IlvAreasOfInterestProperty

java.lang.Object

ilog.views.IlvNamedProperty

ilog.views.maps.IlvAreasOfInterestProperty

All Implemented Interfaces:

IlvPersistentObject, Serializable

public class IlvAreasOfInterestProperty
extends IlvNamedProperty

IlvAreasOfInterestProperty defines a named property used to store the areas of interest in an IlvManager instance that contain cartographic data.
The following code example shows how to use IlvAreasOfInterestProperty:

   // Create a area for all that is visible in the view.
  IlvAreaOfInterest world=IlvJAreaOfInterestPanel.createLocationFromView(view,64,false);
  world.setName("World");
  // Create an area for the bounds of Europe.
  IlvRect rectangle=
     new IlvRect(Math.toRadians(-15),Math.toRadians(35),
                 Math.toRadians(45),Math.toRadians(25));
  IlvAreaOfInterest europe=new IlvAreaOfInterest("Europe",rectangle,0,null);
  // Update the preview image.
  IlvJAreaOfInterestPanel.refreshPreview(view,europe,64);
  // Retrieve or create the areas of interest known to the manager.
  IlvAreaOfInterestVector areas=IlvAreasOfInterestProperty.GetAreasOfInterest(view.getManager());
  // Add the areas to be managed by Beans and/or serialized.
  areas.addElement(world);
  areas.addElement(europe);
  // Zoom to Europe.
  europe.zoomTo(view);

Constructor Detail

IlvAreasOfInterestProperty

public IlvAreasOfInterestProperty(IlvAreaOfInterestVector ap)

Creates a new IlvAreasOfInterestProperty object with the specified areas of interest.

Parameters:

ap - The areas of interest.

IlvAreasOfInterestProperty

public IlvAreasOfInterestProperty(IlvAreasOfInterestProperty source)

Creates a new IlvAreasOfInterestProperty object by copying an existing one.

Parameters:

source - The source property to be copied.

IlvAreasOfInterestProperty

public IlvAreasOfInterestProperty(IlvInputStream stream)
                           throws IlvReadFileException

Creates a new IlvAreasOfInterestProperty object from an IlvInputStream.

Parameters:

stream - The input stream.

Throws:

IlvReadFileException - if an error occurs while reading.

Method Detail

write

public void write(IlvOutputStream stream)
           throws IOException

Writes this property to an IlvOutputStream.

Specified by:

write in interface IlvPersistentObject

Overrides:

write in class IlvNamedProperty

Parameters:

stream - The output stream.

Throws:

IOException - if an I/O exception occurs.

copy

public IlvNamedProperty copy()

Copies the property.

Specified by:

copy in class IlvNamedProperty

Returns:

A new IlvAreasOfInterestProperty instance.

isPersistent

public boolean isPersistent()

Tests if this property can be saved.

Specified by:

isPersistent in class IlvNamedProperty

Returns:

This implementation always returns true.

getAreasOfInterest

public IlvAreaOfInterestVector getAreasOfInterest()

Returns the areas of interest for this property.

Returns:

The areas of interest for this property.

GetAreasOfInterest

public static IlvAreaOfInterestVector GetAreasOfInterest(IlvManager manager)

Returns the areas of interest of a given manager.
This method tries to find the areas of interest of the manager in the following way:

1. If an IlvAreasOfInterestProperty instance is attached to the manager, the areas of interest in the property are returned.
2. If no areas of interest property is attached, a new IlvAreaOfInterestVector is created, stored in the properties of manager and returned.

Parameters:

manager - The manager whose areas of interest you want to retrieve.

Returns:

The areas of interest for manager.
