                                FI.Apply<P,R> apply)

Add a new case statement to this builder.

Parameters:

type - a type to match the argument against

apply - an action to apply to the argument if the type matches

Returns:

a builder with the case statement added

match

public <P> PFBuilder<I,R> match(java.lang.Class<P> type,
                                FI.TypedPredicate<P> predicate,

Parameters:

type - a type to match the argument against

predicate - a predicate that will be evaluated on the argument if the type matches

apply - an action to apply to the argument if the type matches and the predicate returns true

Returns:

a builder with the case statement added

matchEquals

public <P> PFBuilder<I,R> matchEquals(P object,
                                      FI.Apply<P,R> apply)
