Package org.apache.commons.functor.adapter

Class ProcedureUnaryProcedure<A>

  • Type Parameters:
    A - the argument type.
    All Implemented Interfaces:
    java.io.Serializable, Functor, UnaryFunctor<A>, UnaryProcedure<A>
    public final class ProcedureUnaryProcedure<A>
extends java.lang.Object
implements UnaryProcedure<A>, java.io.Serializable
    Adapts a Procedure to the UnaryProcedure interface by ignoring the arguments.

    Note that although this class implements Serializable, a given instance will only be truly Serializable if the underlying functor is. Attempts to serialize an instance whose delegate is not Serializable will result in an exception.

    • Constructor Detail

      • ProcedureUnaryProcedure

        public ProcedureUnaryProcedure​(Procedure procedure)
        Create a new ProcedureUnaryProcedure.
        Parameters:
        procedure - to adapt

    • Method Detail

      • 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​(java.lang.Object that)
        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:
        that - 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 boolean equals​(ProcedureUnaryProcedure<?> that)
        Learn whether another ProcedureUnaryProcedure is equal to this.
        Parameters:
        that - ProcedureUnaryProcedure to test
        Returns:
        boolean

      • 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
        See Also:
        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

      • adapt

        public static <A> ProcedureUnaryProcedure<A> adapt​(Procedure procedure)

        Type Parameters:
        A - the argument type.
        Parameters:
        procedure - to adapt
        Returns:
