Interface JoinComponent

  • All Known Implementing Classes:
    DelegateJoinComponent
    public interface JoinComponent
    a JoinComponent can be used to create builders for creating Join objects. Join objects, in turn, can be used to stream over joined tables.

    It is unspecified if objects returned by builder-type of objects return itself or a new builder. Users should make no assumption of either case and use a fluent API style of programming.

    All methods that takes objects will throw a NullPointerException if provided with one or several null values.

    Intermediate builder methods are not thread safe.

    Currently, this component can build joins of grade 2, 3, 4, 5, 6, 7, 8, 9 or 10.
