 net.refractions.udig.tool.info.LayerPointInfo
| LayerPointInfo | | abstract public class LayerPointInfo (Code) | | The response to a getInfo request of a service w.r.t. a layer.
This LayerPointInfo object allows the wrapping arbitrary content, providing type information as a MIME
type, and the possability of lazy access.
This class is expected to be subclassed inorder to perform lazy parsing via a custom
implementation of getValue();
|
| Method Summary | |
| public Object | acquireValue()
Subclass must implement to acquire value in a lazy manner. | | public ILayer | getLayer()
Layer responsible for providing this information. | | abstract public String | getMimeType()
The data's MIME type.
Well known MIME types:
- "application/vnd.ogc.gml" - represents a FeatureCollection
- "text/html" - represents a web page
- "text/plain"
- "" - indicates LayerPointInfo.EMPTY
The system may be extended at a later time to allow the use of additional MIME types. | | public URL | getRequestURL()

|
| acquireValue | | public Object acquireValue() throws IOException(Code) | | Subclass must implement to acquire value in a lazy manner.
The default implementation will make the request specified by getRequestURL().getContent();
Object to be used as the Value of this LayerPointInfo
throws:
IOException - if an IO error occurs during the request process |
| getLayer | | public ILayer getLayer()(Code) | | Layer responsible for providing this information.
Can be used as a back point to focus the map on the indicated hit.
Returns the layer. |
| getMimeType | | abstract public String getMimeType()(Code) | | The data's MIME type.
Well known MIME types:
- "application/vnd.ogc.gml" - represents a FeatureCollection
- "text/html" - represents a web page

- "" - indicates LayerPointInfo.EMPTY
The system may be extended at a later time to allow the use of additional MIME types. The
goal should be to allow the complete set used in WMS getFeatureInfo opperations.
