Method Detail

caseNil

public static <A,B> Monadics.Matcher<A,B> caseNil(Function0<B> f)

Matches the empty list. Like Haskell's []

caseAN

public static <A,B> Monadics.Matcher<A,B> caseAN(Function2<A,List<A>,B> f)

Matches lists with at least one element. Like Haskell's (x:xs)

caseN

public static <A,B> Monadics.Matcher<A,B> caseN(Function<List<A>,B> f)

Matches any list. Like Haskell's (xs)
