  • Method Details

    • performLifecycleTask

    • findNestedDictionaryAttribute

      protected AttributeDefinition findNestedDictionaryAttribute(String propertyPath)
      Recursively drills down the property path (if nested) to find an AttributeDefinition, the first attribute definition found will be returned

      e.g. suppose parentPath is 'document' and propertyPath is 'account.subAccount.name', first the property type for document will be retrieved using the view metadata and used as the dictionary entry, with the propertyPath as the dictionary attribute, if an attribute definition exists it will be returned. Else, the first part of the property path is added to the parent, making the parentPath 'document.account' and the propertyPath 'subAccount.name', the method is then called again to perform the process with those parameters. The recursion continues until an attribute field is found, or the propertyPath is no longer nested

      Parameters:
      propertyPath - path of the property to use as dictionary attribute and to drill down on
      Returns:
      AttributeDefinition if found, or Null
