Class DefaultValueSpecification<T>

java.lang.Object
  net.sourceforge.domian.specification.AbstractSpecification<T>
      net.sourceforge.domian.specification.DefaultValueSpecification<T>

All Implemented Interfaces:

LeafSpecification<T>, Specification<T>

final class DefaultValueSpecification<T>
extends AbstractSpecification<T>
implements LeafSpecification<T>

Leaf specification, specifying all Java objects with their default value intact. In addition to that, all blank strings are approved as well.

This specification is the only specification which actually approves null-valued candidates.

Specification spec = new DefaultValueSpecification();
spec.isSatisfiedBy(null)               -> true

spec.isSatisfiedBy(false)              -> true
spec.isSatisfiedBy(true)               -> false

spec.isSatisfiedBy("")                 -> true
spec.isSatisfiedBy("   ")              -> true
spec.isSatisfiedBy("\n")               -> true
spec.isSatisfiedBy("\r")               -> true
spec.isSatisfiedBy("\t")               -> true
spec.isSatisfiedBy("\r\n")             -> true
spec.isSatisfiedBy(".")                -> false

spec.isSatisfiedBy(0)                  -> true
spec.isSatisfiedBy(0L)                 -> true
spec.isSatisfiedBy(0.0F)               -> true
spec.isSatisfiedBy(0.0D)               -> true
spec.isSatisfiedBy((short) 0)          -> true
spec.isSatisfiedBy(new Integer(0))     -> true
spec.isSatisfiedBy(new Long(0))        -> true
spec.isSatisfiedBy(new Float(0.00))    -> true
spec.isSatisfiedBy(new Double(0.0000)) -> true
spec.isSatisfiedBy(1)                  -> false
