Query (Metro Web Services Runtime OSGi Bundle 2.4.4 API)

```
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 Jakarta XML Registries specification.
