Constructor Detail

AbstractDefinedFunctor

public AbstractDefinedFunctor(TypedFunctor inner)

Sole Constructor.

Parameters:

inner - is the inner() functor.

Throws:

NullPointerException.

Method Detail

inner

public final TypedFunctor inner()

This method retrieves the functor that is wrapped by this object.

Specified by:

inner in interface DefinedFunctor

Returns:

the inner functor.

apply

public final void apply(ArgumentStack stack)
                 throws java.lang.Throwable

This method performs an invocation of this function object.

Programmers should not call this method directly. Instead, for convenience, call this method indirectly via (F::apply List).

Calling Convention from top to bottom (n >= 0):

1. argument[n]
2. argument[.]
3. argument[2]
4. argument[1]
5. argument[0]

The argument stack will be cleared and then the result will be pushed onto it. If the functor does not return a value, then the stack will remain empty.

Specified by:

apply in interface DefinedFunctor

Specified by:

apply in interface Functor

Parameters:

stack - is a stack containing the arguments being passed to this functor.

Throws:

java.lang.Throwable - in order to propagate exceptions thrown by the functor.

toString

public final java.lang.String toString()

Overrides:

toString in class java.lang.Object
