Method Detail

apply

R apply(P1 p1,
        P2 p2,
        P3 p3,
        P4 p4)
 throws NotAppliedException,
        Lang.Break

Run the function with parameters specified.

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

p2 - the second argument

p3 - the third argument

p4 - the fourth argument

Returns:

whatever value 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
