    • listIterator

      public ListIterator<String> listIterator(int index)
      Specified by:
      listIterator in interface List<String>
      Overrides:
      listIterator in class AbstractList<String>

    • getUnderlyingElements

      public List<?> getUnderlyingElements()
      Description copied from interface: LazyStringList
      Returns an unmodifiable List of the underlying elements, each of which is either a String or its equivalent UTF-8 encoded ByteString or byte[]. It is an error for the caller to modify the returned List, and attempting to do so will result in an UnsupportedOperationException.
      Specified by:
      getUnderlyingElements in interface LazyStringList

    • mergeFrom

      public void mergeFrom(LazyStringList other)
      Description copied from interface: LazyStringList
      Merges all elements from another LazyStringList into this one. This method differs from List.addAll(Collection) on that underlying byte arrays are copied instead of reference shared. Immutable API doesn't need to use this method as byte[] is not used there at all.
      Specified by:
      mergeFrom in interface LazyStringList

    • asByteArrayList

      public List<byte[]> asByteArrayList()
      Description copied from interface: LazyStringList
      Returns a mutable view of this list. Changes to the view will be made into the original list. This method is used in mutable API only.
      Specified by:
      asByteArrayList in interface LazyStringList

    • asByteStringList

      public List<ByteString> asByteStringList()
      Description copied from interface: ProtocolStringList
      Returns a view of the data as a list of ByteStrings.
      Specified by:
      asByteStringList in interface ProtocolStringList

    • getUnmodifiableView

      public LazyStringList getUnmodifiableView()
      Description copied from interface: LazyStringList
      Returns an unmodifiable view of the list.
      Specified by:
      getUnmodifiableView in interface LazyStringList
