public interface Clause
extends no.sesat.commons.visitor.Visitable

A Clause in this project represents a single term or operation on or between terms in a Query string. A heirarchy of Clause objects will therefore represent a Query and avoid unneccessary string manipulations. All Clause subclasses MUST be immutable. State describing information will be stored in the wrapping Query class.
