      key - The key using which the attribute is fetched

      Specified by:
      invalidateMetadata in interface Page

    • hasMetadata

      public boolean hasMetadata()
      Returns true if the page has valid metadata; that is, it has been parsed. Note that this method is a kludge to support our pre-3.0 metadata system, and as such will go away with the new API.
      Specified by:
      hasMetadata in interface Page
      Returns:
      true, if the page has metadata.

    • setHasMetadata

      A debug string.

    • clone

      public WikiPage clone()
      Creates a deep clone of a WikiPage. Strings are not cloned, since they're immutable. Attributes are not cloned, only the internal HashMap (so if you modify the contents of a value of an attribute, these will reflect back to everyone).
      Specified by:
      clone in interface Page
      Overrides:
      clone in class Object

      A deep clone of the WikiPage

      -1, 0 or 1
