L - the left element typeM - the middle element typeR - the right element typepublic final class ImmutableTriple<L,M,R> extends Triple<L,M,R>
An immutable triple consisting of three Object elements.
Although the implementation is immutable, there is no restriction on the objects
that may be stored. If mutable objects are stored in the triple, then the triple
itself effectively becomes mutable. The class is also final, so a subclass
can not add undesirable behavior.

Obtains an immutable triple of three objects inferring the generic types.
This factory allows the triple to be created using inference to obtain the generic types.
