getPatternAsDateFormat

public static java.text.DateFormat getPatternAsDateFormat(TypeDescriptor descriptor)

isUnique

public static boolean isUnique(InstanceDescriptor descriptor)

getUniqueness

getNullQuota

public static double getNullQuota(InstanceDescriptor descriptor)

wrapWithProxy

public static <T> Generator<T> wrapWithProxy(Generator<T> generator,
                                             TypeDescriptor descriptor)

wrapWithProxy
