DtOceanExtractorVisitor tags nodes as static ocean via the setUserValue capability, based on a texture name or texture regular expression.
Terrain nodes have a DtOsgTextureKeyHolder in their userData fields which holds a list of the keys to a texture map of all the textures applied to the node. If one of the textures on the node matches the search string or regular expression than the node has a setUserValue( "isStaticOcean", true ) set on it.

This is the method called when the visitor is visiting groups We detect the DtTerrainPatchGroup (via dynamic cast) as the top-most group, allowing the visitor to do initialization and cleanup.
Cleanup includes removing any texture names from the texture map that are 'extracted'.
