You are thinking about it wrong relatePattern is a function - which is a
kind of expression. You can compare the result of the function using the
equals filter - if you wanted to use it to select content.
Let me provide you a code example (forgive me if this does not work as I am
just typing it into an email from memory).
FilterFactory ff = CommonFactoryFinder.getFilterFactory2(null);
LineString line = (LineString) reader.read("LINESTRING(0 2, 2 0, 8 6)");
Expression expr = ff.function("relatePattern", ff.propert("the_geom"),
ff.literal( linestring), ff.literal("***1*****") );
Filter filter = ff.equals( expr, ff.literal( Boolean.TRUE ) );
