Package org.codice.ddf.spatial.kml.transformer

Class KMLTransformerImpl

java.lang.Object

org.codice.ddf.spatial.kml.transformer.KMLTransformerImpl

All Implemented Interfaces:

ddf.catalog.transform.MetacardTransformer, ddf.catalog.transform.QueryResponseTransformer, KMLTransformer

public class KMLTransformerImpl
extends Object
implements KMLTransformer

The base Transformer for handling KML requests to take a Metacard or SourceResponse and produce a KML representation. This service attempts to first locate a

invalid reference

KMLEntryTransformer

for a given Metacard based on the metadata-content-type. If no

invalid reference

KMLEntryTransformer

can be found, the default transformation is performed.
