Class BinaryProcedureUnaryProcedure<A>

java.lang.Object
org.apache.commons.functor.adapter.BinaryProcedureUnaryProcedure<A>
Type Parameters:
A - the argument type.
All Implemented Interfaces:
Functor, UnaryFunctor<A>, UnaryProcedure<A>
public final class BinaryProcedureUnaryProcedure<A> extends Object implements UnaryProcedure<A>

  • Field Details

    • procedure

      private final BinaryProcedure<? super A, ? super A> procedure
      The adapted procedure.

  • Constructor Details

    • BinaryProcedureUnaryProcedure

      public BinaryProcedureUnaryProcedure(BinaryProcedure<? super A, ? super A> procedure)
      Create a new BinaryProcedureUnaryProcedure.
      Parameters:
      procedure - to adapt

  • Method Details

    • run

      public void run(A obj)
      Execute this procedure.
      Specified by:
      run in interface UnaryProcedure<A>
      Parameters:
      obj - an A parameter to this execution

    • equals

      public boolean equals(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 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).
      See Also:

    • equals

      public boolean equals(BinaryProcedureUnaryProcedure<?> that)
      Learn whether another BinaryProcedureUnaryProcedure is equal to this.
      Parameters:
      that - BinaryProcedureUnaryProcedure to check
      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 Object
      Returns:
      a hash code for this functor
      See Also:

    • toString

      public 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 Object
      Returns:
      a human readable description of this functor

    • adapt

      public static <A> UnaryProcedure<A> adapt(BinaryProcedure<? super A, ? super A> procedure)
      Adapt a BinaryProcedure as a UnaryProcedure.
      Type Parameters:
      A - argument type
      Parameters:
      procedure - BinaryProcedure to adapt
      Returns:
      UnaryProcedure
