The abstract base class for query formatters, which format SIF_Query queries
in another form such as an SQL WHERE clause. The way in which a query is
formatted is determined by the subclass implementation. A subclass must
implement these methods:
- getOpenBrace
- getCloseBrace
- getOperator
- renderField
- renderValue
