javax.xml.registry Interface Query

public interface Query

The Query interface encapsulates a query in a declarative query language. Currently a Query can be an SQL query or an ebXML Filter Query only. In future support for other query languages such as XQL query may be added. The query must conform to a fixed schema as defined by the JAXR specification.
