Method Details

then

public <F> OptionStep6<A,B,C,D,E,F> then(Function5<? super A,? super B,? super C,? super D,? super E,? extends Option<? extends F>> functor)

Apply the provided function with the previous Step results.

Internally this will perform a Option.flatMap(Function) and the result will become the next step value.

Type Parameters:

F - The type of the next step result

Parameters:

functor - The functor to be applied as a flatMap with the previous steps

Returns:

The next step class

then

public <F> OptionStep6<A,B,C,D,E,F> then(Supplier<? extends Option<? extends F>> supplier)

Apply the provided supplier with the previous Step results.

Internally this will perform a Option.flatMap(Function) and the supplier will become the next step value.

This is different to then(Function5) in that the previous step results are not provided for the new step evaluation.

Type Parameters:

F - The type of the next step result

Parameters:

supplier - The supplier to provide the result of the flatMap with the previous step.

Returns:

The next step class

filter

public OptionStep5<A,B,C,D,E> filter(Predicate5<? super A,? super B,? super C,? super D,? super E> predicate)

Apply the provided predicate with the previous step results.

Parameters:

predicate - The check that must be satisfied by contained values

Returns:

This step class with either the same last step value, or changed to none

filterNot

public OptionStep5<A,B,C,D,E> filterNot(Predicate5<? super A,? super B,? super C,? super D,? super E> predicate)

Apply the provided predicate with the previous step results.

Parameters:

predicate - The check that must be dissatisfied by contained values

Returns:

This step class with either the same last step value, or changed to none

Since:

6.1

yield

public <Z> Option<Z> yield(Function5<? super A,? super B,? super C,? super D,? super E,Z> functor)

Terminating step expression, that will provide the previous steps to this function and return the result as a some

Type Parameters:

Z - The type for the returned result

Parameters:

functor - The yield function to map on previous values

Returns:

An Option containing this result or none
