class Filter extends java.lang.Object
A Filter is a predicate or constraint used to match or filter Feature objects.
You can create Filters from CQL:
Filter f = new Filter("name='foobar')
Or you can create Filters from XML:
Filter f = new Filter('<Filter><PropertyIsEqualTo><PropertyName>name</PropertyName><Literal>foobar</Literal></PropertyIsEqualTo></Filter>')
