Class EitherStep6<A,B,C,D,E,F,LEFT>

java.lang.Object

io.atlassian.fugue.extensions.step.EitherStep6<A,B,C,D,E,F,LEFT>

Type Parameters:

A - The right hand side type of the first defined right value

B - The right hand side type of the second defined right value

C - The right hand side type of the third defined right value

D - The right hand side type of the fourth defined right value

E - The right hand side type of the fifth defined right value

F - The right hand side type of the sixth defined right value

LEFT - The left hand side type of the Either result

public final class EitherStep6<A,B,C,D,E,F,LEFT>
extends Object

The sixth step of the Either type.

This class is not intended to be contructed manually, and should only be used as part of a Steps chain, started by Steps.begin(Either)

Modifier and Type	Method and Description
EitherStep6<A,B,C,D,E,F,LEFT>	filter(Predicate6<? super A,? super B,? super C,? super D,? super E,? super F> predicate, Supplier<? extends LEFT> unsatisfiedSupplier) Apply the provided predicate with the previous step results.
<Z> Either<LEFT,Z>	yield(Function6<? super A,? super B,? super C,? super D,? super E,? super F,Z> functor) Terminating step expression, that will provide the previous steps to this function and return the result as a Right

Method Detail

filter

public EitherStep6<A,B,C,D,E,F,LEFT> filter(Predicate6<? super A,? super B,? super C,? super D,? super E,? super F> predicate,
                                            Supplier<? extends LEFT> unsatisfiedSupplier)

Apply the provided predicate with the previous step results.

If the predicate is not satisfied then the unsatisfiedSupplier is used to populate the left value that will prevent any further steps evaluation.

Parameters:

predicate - The check that must be satisfied by contained values

unsatisfiedSupplier - Provide the value to populate the left if not satisfied

Returns:

This step class with either the same last step value, or changed to a left

yield

public <Z> Either<LEFT,Z> yield(Function6<? super A,? super B,? super C,? super D,? super E,? super F,Z> functor)

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

Type Parameters:

Z - The right hand side type for the returned result

Parameters:

functor - The yield function to map on previous values

Returns:

An Either with the result of this function on right, or the existing left
