java.lang.Object org.apache.commons.functor.core.composite.UnaryOr<A>
public final class UnaryOr<A>
Tests
true
iff
at least one of its children test true
.
Note that by this definition, the "or" of
an empty collection of predicates tests false
.
Note that although this class implements
Serializable
, a given instance will
only be truly Serializable
if all the
underlying functors are. Attempts to serialize
an instance whose delegates are not all
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.
