public class ProjectionFactoryLoader
extends OMComponent

All this class does is add the instance of the ProjectionFactory to the MapHandler. This class needs to be added to the MapHandler in order for a ProjectionFactory to be created and the ProjectionLoaders to be recognized by the application. To keep multiple ProjectionLoaders out of the openmap.components property for readability, this class has a property that lets you set which ProjectionLoaders are created and added to the application:

 
 
  # For a projFactoryLoader marker name added to the openmap.components property.
  projFactoryLoader.class=com.bbn.openmap.proj.ProjectionFactoryLoader
  projFactoryLoader.class=com.bbn.openmap.proj.ProjectionFactoryLoader
  projFactoryLoader.projectionLoaders=mercatorloader cadrgloader ortholoader llxyloader gnomonicloader
  projFactoryLoader.mercatorloader.class=com.bbn.openmap.proj.MercatorLoader
  projFactoryLoader.cadrgloader.class=com.bbn.openmap.proj.CADRGLoader
  projFactoryLoader.ortholoader.class=com.bbn.openmap.proj.OrthographicLoader
  projFactoryLoader.llxyloader.class=com.bbn.openmap.proj.LLXYLoader
  projFactoryLoader.gnomonicloader.class=com.bbn.openmap.proj.GnomonicLoader
 
  
 
The above properties create 5 ProjectionLoaders which are added to the MapHandler, along with the ProjectionFactory singleton instance. The ProjectionLoader may have additional properties which can be set as well, like their pretty GUI name and description.

Method Detail

setBeanContext

public void setBeanContext(java.beans.beancontext.BeanContext in_bc)
                    throws java.beans.PropertyVetoException
When the BeanContext (MapHandler) gets set, the singleton instance of the ProjectionFactory is created (asked for) and added to the BeanContext.

Specified by:
setBeanContext in interface java.beans.beancontext.BeanContextChild
Overrides:
setBeanContext in class MapHandlerChild
java.beans.PropertyVetoException

setProperties

public void setProperties(java.lang.String prefix,
                          java.util.Properties props)
Check the properties for those to create ProjectionLoaders.

Specified by:
setProperties in interface PropertyConsumer
Overrides:
setProperties in class OMComponent
Parameters:
prefix - the token to prefix the property names
props - the Properties object

getProperties

public java.util.Properties getProperties(java.util.Properties props)
Create the properties to create ProjectionLoaders that this loader created.

Specified by:
getProperties in interface PropertyConsumer
Overrides:
getProperties in class OMComponent
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)
Create the property information reflecting those used to create loaders.

Specified by:
getPropertyInfo in interface PropertyConsumer
Overrides:
getPropertyInfo in class OMComponent
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.
