public class GraphicLoaderConnector
extends OMComponent

The GraphicLoaderConnector is a MapHandler membership listener, looking for GraphicLoaders without receivers. This class uses the MapHandler to find GraphicLoaders, and requires the LayerHandler to be added to the MapHandler, also.

If the GraphicLoaderConnector finds a GraphicLoader that is not * hooked up to a receiver, it creates a GraphicLoaderPlugIn and PlugInLayer, and adds the PlugInLayer to the LayerHandler. This causes the LayerHandler to add the layer to the application. If the GraphicLoaderConnector doesn't have a handle to the LayerHandler when it finds a GraphicLoader, it adds the PlugInLayer it created to an internal list to add to the LayerHandler when the connector finds one.

Constructor Detail

GraphicLoaderConnector

public GraphicLoaderConnector()

Method Detail

setNewLayerIndex

public void setNewLayerIndex(int i)

Set the index of any new layers to be added to the LayerHandler. Negative numbers put the layer on top of the map.

getNewLayerIndex

public int getNewLayerIndex()

setNewLayerVisible

public void setNewLayerVisible(boolean set)

Set whether the new layers should initially be visible when they are added to the map.

setNewLayerVisible

public boolean setNewLayerVisible()

setLayerHandler

public void setLayerHandler(LayerHandler lh)

Set the LayerHandler to be notified with any new PlugIn layers containing the new GraphicLoaderPlugIns.

getLayerHandler

public LayerHandler getLayerHandler()

checkGraphicLoader

public void checkGraphicLoader(GraphicLoader gl)

Check to see if the GraphicLoader already has a receiver set inside it. If it doesn't call hookUpGraphicLoaderWithLayer();

hookUpGraphicLoaderWithLayer

public void hookUpGraphicLoaderWithLayer(GraphicLoader gl)

Assumes that the GraphicLoader doesn't already have a receiver. Creates a GraphicLoaderPlugIn, and a PlugInLayer, and hooks everything up. Then hands the PlugInLayer to the LayerHandler to get set on the map.

findAndInit

public void findAndInit(java.lang.Object obj)

Find GraphicLoaders and LayerHandler in the MapHandler.

Specified by:

findAndInit in interface LightMapHandlerChild

Overrides:

findAndInit in class MapHandlerChild

findAndUndo

public void findAndUndo(java.lang.Object obj)

Description copied from class: MapHandlerChild

The childrenRemoved has been changed to go through its iterator to call this method with every object. This lets subclasses call this method on their super class, so it can handle what it needs to with objects it may be interested in.

Specified by:

findAndUndo in interface LightMapHandlerChild

Overrides:

findAndUndo in class MapHandlerChild

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 OMComponent

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 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 list)

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 OMComponent

Parameters:

list - 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.
