public class CartesianLoader
extends BasicProjectionLoader
implements ProjectionLoader

ProjectionLoader to add the Cartesian projection to an OpenMap application. There are some properties you can set for the Cartesian projection, namely limits on where it can pan. If you don't set the limits, the projection will just keep going. You can use the anchorX and anchorY settings to hold the map against some of the limits.

  topLimit=top coordinate limit
  bottomLimit=bottom coordinate limit
  leftLimit=left side coordinate limit
  rightLimit=right side coordinate limit
  anchorX=horizontal coordinate to set on projection before checking limits
  anchorY=vertical coordinate to set on projection before checking limits

leftLimit

protected double leftLimit

The coordinate limit of the left side of the projection. If the left side of the map projection would show coordinates more left than this value, the center of the map will be changed so that this value is on the edge.

rightLimit

protected double rightLimit

The coordinate limit of the right side of the projection. If the right side of the map projection would show coordinates more right than this value, the center of the map will be changed so that this value is on the edge.

topLimit

protected double topLimit

The coordinate limit of the top side of the projection. If the top side of the map projection would show coordinates higher than this value, the center of the map will be changed so that this value is on the edge.

bottomLimit

protected double bottomLimit

The coordinate limit of the bottom side of the projection. If the bottom side of the map projection would show coordinates lower than this value, the center of the map will be changed so that this value is on the edge.

limitAnchorPoint

protected java.awt.geom.Point2D limitAnchorPoint

A point that can be used for force the projection against the limits. Is only used if the limits are set to be something other than infinity.

Method Detail

create

public Projection create(java.util.Properties props)
                  throws ProjectionException

Create the projection with the given parameters.

Specified by:

create in interface ProjectionLoader

Specified by:

create in class BasicProjectionLoader

Throws:

ProjectionException - if a parameter is missing or invalid

setProperties

public void setProperties(java.lang.String prefix,
                          java.util.Properties props)

Description copied from class: OMComponent

Sets the properties for the OMComponent.

Specified by:

setProperties in interface PropertyConsumer

Overrides:

setProperties in class BasicProjectionLoader

Parameters:

prefix - the token to prefix the property names

props - the Properties object

getProperties

public java.util.Properties getProperties(java.util.Properties props)

Description copied from class: OMComponent

PropertyConsumer method, to fill in a Properties object, reflecting the current values of the OMComponent. If the component has a propertyPrefix set, the property keys should have that prefix plus a separating '.' prepended to each property key it uses for configuration.

Specified by:

getProperties in interface PropertyConsumer

Overrides:

getProperties in class BasicProjectionLoader

Parameters:

props - a Properties object to load the PropertyConsumer properties into. If props equals null, then a new Properties object should be created.

Returns:

Properties object containing PropertyConsumer property values. If getList was not null, this should equal getList. Otherwise, it should be the Properties object created by the PropertyConsumer.

getPropertyInfo

public java.util.Properties getPropertyInfo(java.util.Properties props)

Description copied from class: OMComponent

Method to fill in a Properties object with values reflecting the properties able to be set on this PropertyConsumer. The key for each property should be the raw property name (without a prefix) with a value that is a String that describes what the property key represents, along with any other information about the property that would be helpful (range, default value, etc.). For Layer, this method should at least return the 'prettyName' property.

Specified by:

getPropertyInfo in interface PropertyConsumer

Overrides:

getPropertyInfo in class BasicProjectionLoader

Parameters:

props - a Properties object to load the PropertyConsumer properties into. If getList equals null, then a new Properties object should be created.

Returns:

Properties object containing PropertyConsumer property values. If getList was not null, this should equal getList. Otherwise, it should be the Properties object created by the PropertyConsumer.
