Class ImmutableEither.Builder<L,R>

java.lang.Object

de.flapdoodle.transition.types.ImmutableEither.Builder<L,R>

Enclosing class:

ImmutableEither<L,R>

public static final class ImmutableEither.Builder<L,R>
extends Object

Builds instances of type ImmutableEither. Initialize attributes and then invoke the build() method to create an immutable instance.

Builder is not thread-safe and generally should not be stored in a field or collection, but instead used immediately to create instances.

this builder for use in a chained invocation

optLeft

public final ImmutableEither.Builder<L,R> optLeft(L optLeft)

Initializes the optional value optLeft to optLeft.

Parameters:

optLeft - The value for optLeft

Returns:

this builder for chained invocation

optLeft

public final ImmutableEither.Builder<L,R> optLeft(Optional<L> optLeft)

Initializes the optional value optLeft to optLeft.

Parameters:

optLeft - The value for optLeft
