    • setCarryAspectProperties

      public void setCarryAspectProperties(boolean carryAspectProperties)
      Whether or not aspect-related properties must be carried to the new version of the node
      Parameters:
      carryAspectProperties - true (default) to carry all aspect-linked properties forward. false will clean the aspect of any unextracted values.

    • setEnableStringTagging

      public void setEnableStringTagging(boolean enableStringTagging)
      Whether or not to enable mapping of simple strings to cm:taggable tags
      Parameters:
      enableStringTagging - true find or create tags for each string mapped to cm:taggable. false (default) ignore mapping strings to tags.

    • setStringTaggingSeparators

      public void setStringTaggingSeparators(List<String> stringTaggingSeparators)
      List of string separators - note: all will be applied to a given string

      stringTaggingSeparators -

    • addTags

      protected void addTags(NodeRef actionedUponNodeRef, PropertyDefinition propertyDef, Serializable rawValue)
      Iterates the values of the taggable property which the metadata extractor should have already attempted to convert values to NodeRefs.

      If conversion by the metadata extracter failed due to a MalformedNodeRefException the taggable property should still contain raw string values.

      Mixing of NodeRefs and string values is permitted so each raw value is checked for a valid NodeRef representation and if so, converts to a NodeRef, if not, adds as a tag via the TaggingService.

      Parameters:
      actionedUponNodeRef - The NodeRef being actioned upon
      propertyDef - the PropertyDefinition of the taggable property
      rawValue - the raw value from the metadata extracter

    • splitTag

      protected List<String> splitTag(String str)

    • isExecuteAsynchronously

      public boolean isExecuteAsynchronously(NodeRef actionedUponNodeRef)
      Used by the action service to work out if it should override the executeAsychronously value when it is know the extract will take place asynchronously anyway. Results in the action being processed post commit, which allows it to see node changes.
      Parameters:
      actionedUponNodeRef - the node to be processed.
      Returns:
      true if the AsynchronousExtractor will be used. false otherwise.
