ScalarValue (VTL Engine 1.0.8 API)

Type Parameters:

R - the Java class that is used to hold the effective value of this ScalarValue for computational purposes. Usually hidden as an implementation detail.

S - the ValueDomainSubset of this value.

D - the basic ValueDomain as defined by VTL specification.

All Superinterfaces:

Comparable<ScalarValue<?,?,?,?>>, Serializable, Supplier<R>, VTLValue

All Known Subinterfaces:

CodeItem<I,R,S,D>, NumberValue<T,R,S,D>, StringEnumeratedDomainSubset.StringCodeItem<I>

All Known Implementing Classes:

BaseScalarValue, BooleanValue, DateValue, DoubleValue, DurationValue, IntegerValue, NullValue, NumberValueImpl, StringCodeList.StringCodeItemImpl, StringValue, TimePeriodValue, TimeValue
```
public interface ScalarValue<T extends ScalarValue<T,R,S,D>,R extends Comparable<?> & Serializable,S extends ValueDomainSubset<S,D>,D extends ValueDomain>
extends VTLValue, Supplier<R>, Serializable, Comparable<ScalarValue<?,?,?,?>>
```
An interface describing VTL scalar values, as defined by the specification.
