Examples of Optional

A common alternative to using this class is to find or create a suitable null object for the type in question.

This class is not intended as a direct analogue of any existing "option" or "maybe" construct from other programming environments, though it may bear some similarities. @param < T> the type of instance that can be contained. {@code Optional} is naturallycovariant on this type, so it is safe to cast an {@code Optional} to {@code Optional} for any supertype {@code S} of {@code T}. @author Kurt Alfred Kluever @author Kevin Bourrillion @since Guava release 10

  • org.eclipse.papyrus.sysml.activities.Optional
    A representation of the model object ' Optional'.

    The following features are supported:

    • {@link org.eclipse.papyrus.sysml.activities.Optional#getBase_Parameter Base Parameter}

    @see org.eclipse.papyrus.sysml.activities.ActivitiesPackage#getOptional() @model @generated
  • org.hamcrest.text.pattern.internal.ast.Optional
  • org.jrdf.query.expression.Optional
  • org.supercsv.cellprocessor.Optional
    This processor returns null if it meets the empty String in a column and does not call subsequent processors in its chain. It is a simple customization of the MagicToken. If you need to return different values than null, use that class instead. @author Kasper B. Graversen
