Class NullabilityHolder


  • public class NullabilityHolder
    extends java.lang.Object
    Instances of this class simply track whether a value at an index is null. For simplicity and performance, it is expected that various setter methods setNull(int), setNulls(int, int), setNotNull(int) and setNotNulls(int, int) are invoked with monotonically increasing values for the index parameter.
