  • Method Summary

    Modifier and Type
    Method
    Description

    find(int index)
    Retrieves a Holder containing the (possibly null) value at the specified index if it exists.
    T
    get(int index)
    Retrieve the value.
    default Indexed<T>
    prefix(int size)
     
    default Indexed<T>
    reversed()
     
    int
    size()
    Retrieve the number of values available in the container.
    default <U> Indexed<U>
    transformed(Func1<T,U> transforminator)
     

  • Method Details

    • get

      T get(int index)
      Retrieve the value. The index must be valid for the container's current size (i.e. [0-size)
      Throws:
      IndexOutOfBoundsException - if index is out of bounds

    • size

      int size()
      Retrieve the number of values available in the container.

    • find

      @Nonnull Maybe<T> find(int index)
      Retrieves a Holder containing the (possibly null) value at the specified index if it exists. If no such value exists returns an empty Holder.

    • transformed

      default <U> Indexed<U> transformed(Func1<T,U> transforminator)

    • reversed

      @Nonnull default Indexed<T> reversed()

    • prefix

      @Nonnull default Indexed<T> prefix(int size)
