Class BooleanValue

java.lang.Object
  org.qtitools.qti.value.SingleValue
      org.qtitools.qti.value.BooleanValue

All Implemented Interfaces:

java.io.Serializable, Value

public class BooleanValue
extends SingleValue

Implementation of BaseType boolean value.

Legal String representations of boolean value are: true, 1, false, 0.

This class is not mutable and cannot contain NULL value.

Cardinality of this class is always single and BaseType is always boolean.
