java.lang.Object org.apache.commons.functor.core.composite.Not
public final class Not
Tests
to the logical inverse
of some other predicate.
Note that although this class implements
Serializable
, a given instance will
only be truly Serializable
if the
underlying functor is. Attempts to serialize
an instance whose delegate is not
Serializable
will result in an exception.

Additionally, this method can return
true only if the specified Object implements
the same functor interface and is known to produce the same
results and/or side-effects for the same arguments (if any).
While implementators are strongly encouraged to override
the default Object implementation of this method,
note that the default Object implementation
does in fact adhere to the functor equals
contract.
