Constructor and Description |

AnyMValueImpl(Monad<T> monad,
java.lang.Class initialType) |
Modifier and Type | Method and Description |
---|---|
AnyMValue<java.util.List<T>> |
aggregate(AnyM<T> next)
Aggregate the contents of this Monad and the supplied Monad
|
<R> AnyMValue<R> |
applyM(AnyMValue<java.util.function.Function<? super T,? extends R>> fn)
Apply function/s inside supplied Monad to data in current Monad
e.g.
|
<R> AnyMValue<R> |
bind(java.util.function.Function<? super T,?> fn)
Perform a looser typed flatMap / bind operation
The return type can be another type other than the host type
Note the modified javaslang monad laws are not applied during the looser typed bind operation
The modification being used to work around the limits of the Java type system.
|
<T> AnyMValue<T> |
empty()
Construct an AnyM wrapping an empty instance of the wrapped type
e.g.
|
<T> AnyMValue<T> |
emptyUnit() |
boolean |
equals(java.lang.Object obj) |
AnyMValue<T> |
filter(java.util.function.Predicate<? super T> p)
Perform a filter operation on the wrapped monad instance e.g.
|
<R> AnyMValue<R> |
flatMap(java.util.function.Function<? super T,? extends AnyMValue<? extends R>> fn)
flatMap operation
AnyM follows the javaslang modified 'monad' laws https://gist.github.com/danieldietrich/71be006b355d6fbc0584
In particular left-identity becomes
Left identity: unit(a).flatMap(f) ≡ select(f.apply(a))
Or in plain English, if your flatMap function returns multiple values (such as flatMap by Stream) but the current Monad only can only hold one value,
only the first value is accepted.
