## Interface TriFunction<A,B,C,R>

- Type Parameters:
    `A` - the type of the first argument to the function
    `B` - the type of the second argument to the function
    `C` - the type of the third argument to the function
    `R` - the type of the result of the function
  All Known Subinterfaces:
    DroolsCondition.Mutator<InTuple,OutPatternVar,R,C>
  Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

      @FunctionalInterface
      public interface TriFunction<A,B,C,R>

  Represents a function that accepts three arguments and produces a result. This is the three-arity specialization of `Function`.
