      • define

        public Type define​(DataObject dataObject)
        Description copied from interface: TypeHelper
        Define the DataObject as a Type. The Type is available through TypeHelper.getType(java.lang.String, java.lang.String) methods. If a type with the same name already exists, it is returned and no new definition takes place. If the uri property of the type to be defined is set to "", then the resulting type will have no uri, same as if the uri property was set to null.
        Specified by:
        define in interface TypeHelper
        Parameters:
        dataObject - the DataObject representing the Type.
        Returns:
        the defined Type.

        public Type define​(DataObject dataObject,
                   List types)
        Define the DataObject as a Type. The Type is available through TypeHelper and DataGraph getType() methods.
        Parameters:
        dataObject - the DataObject representing the Type.
        Returns:
        the defined Type.
        Throws:
        IllegalArgumentException - if the Type could not be defined.

      • define

        public List define​(List types)
        Define the list of DataObjects as Types. The Types are available through TypeHelper and DataGraph getType() methods.

        Parameters:
        types - a List of DataObjects representing the Types.
        Returns:
        the defined Types.
        Throws:
        IllegalArgumentException - if the Types could not be defined.
