FilterCapabilities.support(Filter) does not check the expressions used in the
filters
-------------------------------------------------------------------------------------
Key: GEOT-1801
URL: http://jira.codehaus.org/browse/GEOT-1801
Project: GeoTools
Issue Type: Bug
Components: core filter
Affects Versions: 2.5-M1, 2.4.2
Reporter: Andrea Aime
Fix For: 2.4.3, 2.5-M2
This may lead to declaring a filter as supported when it internally uses a
function that's not supported. For example, the following test
public void testFunction() throws Exception {
PropertyIsEqualTo equal = ff.equal(ff.property("col"),
ff.function("abs", ff.literal(5)), false);
SQLEncoder encoder = new SQLEncoder();
assertTrue(encoder.getCapabilities().fullySupports(equal));
encoder.encode(equal);
}
breaks when trying to encode the equal filter, whilst in theory it should break
in the assertTrue (the filter is not actually fully supported at all...)
