B.14. The Type Facility

The Translator API contains an interface TypeFacility that defines data types and provides value translation facilities. This interface can be obtained from calling the ExecutionFactory.getTypeFacility() method.

The TypeFacility interface has methods that support data type transformation and detection of appropriate runtime or JDBC types. The TypeFacility.RUNTIME_TYPES and TypeFacility.RUNTIME_NAMES interfaces defines constants for all JBoss Data Virtualization runtime data types. All Expression instances define a data type based on this set of types. These constants are often needed in understanding or creating language interfaces.
