Nested Class Summary | |
---|---|
interface | ComposeBinary.Visitor
Interface for classes that may interpret a ComposeBinary functor. |
Constructor Summary | |
---|---|
ComposeBinary(BinaryFunctor<T1,T2,F1> f, BinaryFunctor<T1,T2,F2> g, BinaryFunctor<F1,F2,R> h)
Builds a ComposeBinary functor, given two inner functors f and
g, and outer functor h. |
Method Summary | |
---|---|
void | accept(Visitor v)
Calls the Visitor's visit(ComposeBinary) method, if it
implements the nested Visitor interface. |
R | fn(T1 x, T2 y)
Given argument x, passes x to both inner functors, and passes the
results of those functors to the outer functor.
|
BinaryFunctor<T1,T2,F1> | getFirstInner()
Returns the first of two inner functors |
BinaryFunctor<F1,F2,R> | getOuter()
Returns the outer functor |
BinaryFunctor<T1,T2,F2> | getSecondInner()
Returns the second of two inner functors |
String | toString() |
Throws: IllegalArgumentException if any of the functors is missing
