Method Summary

Modifier and Type	Method and Description
R	apply(P1 p1, P2 p2) Apply the two params to the function

Method Detail

apply

R apply(P1 p1,
        P2 p2)
 throws NotAppliedException,
        Lang.Break

Apply the two params to the function

In case implementing a partial function, it can throw out an NotAppliedException if the function is not defined for the given parameter(s)

Parameters:

p1 - the first argument of type P1

p2 - the second argument of type P2

Returns:

the result of type R

Throws:

NotAppliedException - if the function doesn’t apply to the parameter(s)

Lang.Break - to short cut collecting operations (fold/reduce) on an container
