Package org.geotools.filter

Interface Summary

BetweenFilter	Defines a 'between' filter (which is a specialized compare filter).

EnvironmentVariable	DOCUMENT ME!
FidFilter	Defines a feature ID filter, which holds a list of feature IDs.
Filter	Defines an OpenGIS Filter object, with default behaviors for all methods.
FilterFactory	This specifies the interface to create filters.
FilterHandler	Interface to recieve filters from the filter sax parsing classes.
FilterType	The FilterType interface lists all the possible type of filter.
FilterVisitor	An interface for classes that want to perform operations on a Filter hiarachy.
GeometryDistanceFilter	Defines geometry filters with a distance element.
GeometryFilter	Implements a geometry filter.
LikeFilter	Defines a like filter, which checks to see if an attribute matches a REGEXP.
