Examples of org.locationtech.udig.tool.info.LayerPointInfo

org.locationtech.udig.tool.info.LayerPointInfo
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();
