Constructor Detail

TransformedProcedure

public TransformedProcedure(Function<? extends X> function,
                            UnaryProcedure<? super X> procedure)

Create a new TransformedProcedure.

Type Parameters:

X -

Parameters:

function - Function

procedure - UnaryProcedure

Method Detail

run

public final void run()

Execute this procedure.

Specified by:

run in interface Runnable

Specified by:

run in interface Procedure

equals

public final 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).

Functor.hashCode()

equals

public final boolean equals(TransformedProcedure that)

Learn whether another TransformedProcedure 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 Object

Returns:

a hash code for this functor

See Also:

Functor.equals(java.lang.Object)

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
