      • TransformedBinaryProcedure

        public TransformedBinaryProcedure​(BinaryFunction<? super L,​? super R,​? extends X> function,
                                  UnaryProcedure<? super X> procedure)
        Create a new TransformedBinaryProcedure.
        Type Parameters:
        X - the wrapped procedure argument.
        Parameters:
        function - BinaryFunction
        procedure - UnaryProcedure

    • Method Detail

      • run

        public final void run​(L left,
                      R right)
        Execute this procedure.
        Specified by:
        run in interface BinaryProcedure<L,​R>
        Parameters:
        left - the L element of the ordered pair of arguments
        right - the R element of the ordered pair of arguments

      • equals

        public final boolean equals​(java.lang.Object obj)
        Indicates whether some other object is "equal to" this functor. This method must adhere to general Object.equals contract. 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.

        Specified by:
        equals in interface Functor
        Overrides:
        equals in class java.lang.Object
        Parameters:
        obj - the object to compare this functor to
        Returns:
        true iff the given object implements this functor interface, and is known to produce the same results and/or side-effects for the same arguments (if any).

        Functor.hashCode()

      • equals

        public final boolean equals​(TransformedBinaryProcedure<?,​?> that)
        Learn whether another TransformedBinaryProcedure is equal to this.
        Parameters:
        that - instance to test
        Returns:
        whether equal

      • hashCode

        public int hashCode()
        Returns a hash code for this functor adhering to the general Object.hashCode contract. Implementators are strongly encouraged but not strictly required to override the default Object implementation of this method.
        Specified by:
        hashCode in interface Functor
        Overrides:
        hashCode in class java.lang.Object
        Returns:
        a hash code for this functor

        Functor.equals(java.lang.Object)

      • toString

        public java.lang.String toString()
        Returns a human readable description of this functor. Implementators are strongly encouraged but not strictly required to override the default Object implementation of this method.
        Specified by:
        toString in interface Functor
        Overrides:
        toString in class java.lang.Object
        Returns:
        a human readable description of this functor
