public class QueryBuilder
extends Object

This class is a helper that enables users to easily build SIREn's JSON queries.

More information about the JSON query syntax can be found in JsonQueryParser.

The builder enables the creation of AbstractQuery which can then be converted into a JSON representation using the method AbstractQuery.toString() or into a Query using the method AbstractQuery.toQuery(boolean).
