      public static FieldName name(String value)
      Create a new FieldName that treats the given value as is.
      Parameters:
      value - must not be null.

      new instance of FieldName.

    • path

      public static FieldName path(String value)

      Returns:
      new instance of FieldName.

    • parts

      public String[] parts()
      Get the parts the field name consists of. If the FieldName is a FieldName.Type.KEY or a FieldName.Type.PATH that does not contain dot (.) characters an array containing a single element is returned. Otherwise the name() is split into segments using dot (.) as a separator.
      Returns:
      never null.

    • isOfType

      public boolean isOfType(FieldName.Type type)
      Parameters:

      Returns:
      whether the field name represents a key (i.e. as-is name).
