Package org.apache.cayenne.access.types
Class BooleanType

- All Implemented Interfaces:
ExtendedType<Boolean>
- Direct Known Subclasses:
IngresBooleanType
public class BooleanType extends Object implements ExtendedType<Boolean>
Handlesjava.lang.Booleanmapping. Note that "materialize*" methods return either Boolean.TRUE or Boolean.FALSE, instead of creating new Boolean instances using constructor. This makes possible identity comparison such asobject.getBooleanProperty() == Boolean.TRUE.- Since:
- 1.2
