Class BooleanType
java.lang.Object
org.apache.cayenne.access.types.BooleanType
- All Implemented Interfaces:
ExtendedType<Boolean>
- Direct Known Subclasses:
IngresBooleanType
Handles
java.lang.Boolean
mapping. 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 as
object.getBooleanProperty() == Boolean.TRUE
