Constructor for a DataFile.
@type flow_element: FlowElement
- Parameters
-
- flow_element - The FlowElement using the datafile @type identifier : string
- identifier - : Name of the datafile @type update_url_params: dict
- update_url_params - Dictionary containing parameters used to construct the datafile update url @type data: mixed
- data - Data to use in the datafile if kept in memory rather than file @type path: string
- path - path to the data file itself @type temp_directory: string
- temp_directory - temporary file location (defaults to the operating system defualt) @type create_temp_copy: bool
- create_temp_copy - whether to copy datafile to temporary location when updating @type auto_update: bool
- - auto_update: whether to automatically update the datafile when required @type file_system_watcher: bool
- file_system_watcher - whether to check the datafile's path for changes and update the connected FlowElement's data automatically when the file is changed in the operating system @type polling_interval: int
- polling_interval - How often to poll for updates to the datafile (minutes) @type update_time_maximum_randomisation : int
- update_time_maximum_randomisation - : Maximum randomisation offset in seconds to polling time interval @type verify_md5 : bool
- verify_md5 - : whether to check a 'content-md5' header in the data file update service against the datafile to verify its contents @type decompress: bool
- - is the datafile gziped when returning from the update service? @type download: bool
- download - should the datafile be downloaded or stored in memory @type update_on_start : bool
- update_on_start - : When this is set to true the datafile is updated / downloaded immediately on initialisation. This is useful if no initial datafile is present. @type verify_if_modified_since : bool
- verify_if_modified_since - : whether to check an "If-Modified-Since" header on the update service against the last datafile update date
