Constructor Detail

StyledMapRenderer

public StyledMapRenderer(java.awt.Component owner)

Construct a new renderer for the specified component.

Parameters:

owner - The widget that own this renderer, or null if none.

StyledMapRenderer

public StyledMapRenderer(java.awt.Component owner,
                         RenderedLayerFactory factory)

Construct a new renderer using the specified factory.

Parameters:

owner - The widget that own this renderer, or null if none.

factory - DOCUMENT ME!

Method Detail

setMapContext

public void setMapContext(MapContext mapContext)
                   throws org.opengis.referencing.operation.TransformException,
                          java.io.IOException,
                          IllegalAttributeException

Set a new context as the current one. This method performs the following steps:

• Remove all previous layers.
• Set the coordinate system to the context CS.
• Add all layers found in the context.
• Register listeners for feature changes.

Parameters:

mapContext - The new context, ornull for removing any previous context.

Throws:

org.opengis.referencing.operation.TransformException - DOCUMENT ME!

java.io.IOException - DOCUMENT ME!

IllegalAttributeException - DOCUMENT ME!

addLayer

protected void addLayer(MapLayer layer)
                 throws org.opengis.referencing.operation.TransformException,
                        java.io.IOException,
                        IllegalAttributeException

Add a layer to this renderer. A single Layer may be converted into an arbitrary amount of RenderedLayers. Those rendered layers will have values as 4.0, 4.1, 4.2, etc. where 4 is the layer number, and .0, .1, .2... is the rendered layer number for this particular layer.

Parameters:

layer - The layer to add.

Throws:

org.opengis.referencing.operation.TransformException - if some feature in the layer use an incompatible coordinate system.

java.io.IOException - DOCUMENT ME!

IllegalAttributeException - DOCUMENT ME!

java.lang.AssertionError - DOCUMENT ME!

insertLayer

public void insertLayer(MapLayer layer,
                        int position)
                 throws org.opengis.referencing.operation.TransformException,
                        java.io.IOException,
                        IllegalAttributeException

Add a layer to this renderer. A single Layer may be converted into an arbitrary amount of RenderedLayers. Those rendered layers will have values as 4.0, 4.1, 4.2, etc. where 4 is the layer number, and .0, .1, .2... is the rendered layer number for this particular layer.

Parameters:

layer - The layer to add.

position - DOCUMENT ME!

Throws:

org.opengis.referencing.operation.TransformException - if some feature in the layer use an incompatible coordinate system.

java.io.IOException - DOCUMENT ME!

IllegalAttributeException - DOCUMENT ME!

java.lang.AssertionError - DOCUMENT ME!

removeLayer

public void removeLayer(MapLayer layer)

Remove a layer from this renderer. Nothing is done if the specified layer is null or not found in this renderer.

Parameters:

layer - The layer to remove.

removeAllLayers

public void removeAllLayers()

Remove all layers from this renderer.

Overrides:

removeAllLayers in class Renderer
