Re: [Geotools-gt2-users] CQL: How to get relate/de9im filter? (which works as ST_Relate(geometry geomA, geometry geomB, text intersectionMatrixPattern))

[Jody G. <jod...@gm...>]

They do provide a function - so you should be able to create a "relatePattern" function call. If that works we have a clear reason (and code example) to create a issue report in the JIRA issue tracker.
