Class FennelStandardTypeDescriptor

java.lang.Object
  org.eigenbase.util14.Enum14.BasicValue
      net.sf.farrago.fennel.tuple.FennelStandardTypeDescriptor

All Implemented Interfaces:

Serializable, Comparable, FennelStoredTypeDescriptor, Enum14.Value

Direct Known Subclasses:

FennelStandardTypeDescriptor.FennelType

public abstract class FennelStandardTypeDescriptor
extends Enum14.BasicValue
implements FennelStoredTypeDescriptor

FennelStandardTypeDescriptor implements the FennelStandardTypeDescriptor enumerations as kept in fennel. This must be kept in sync with any changes to fennel's FennelStandardTypeDescriptor.h. This class is JDK 1.4 compatible.
