DFDLOCALE{...} -- renders a formatted list of data type translations by process

  • Parameters:
    Parameter Description Default
    id Process ID none, required parameter
    name A text description of this locale value of id
    url Specify a URL to be used when clicking on this particular locale in data flow diagrams Wiki page where this data flow diagram is found
    deprecated Indicates whether this locale is still in use and how and when it will be rendered 0
    connect Connections via transports to other locales none

Locales are rendered in diagrams as Graphviz cluster subgraphs. The subgraph will be labeled using name. The connect parameter is used to determine whether non-multicast data can flow between two locales.

The format of the connect parameter is a comma-separated list of pairs of locale|transport. As an example:

%DFDLOCALE{id="here" name="My Place" connect="there|ICMP"}%
%DFDLOCALE{id="there" name="Your Place"}%

In the above example, data utilizing the ICMP transport can flow from here to there, but not from there to here.

Note: There are no defaults for connections even for the self-locale. This means that in the above example, data utilizing the ICMP transport cannot be sent from here to here successfully. To remedy that, define your locale in the following fashion:

%DFDLOCALE{id="elsewhere" name="Another Place" connect="elsewhere|ICMP, there|ICMP, here|ICMP"}%

The above example allows the elsewhere locale to send data via ICMP to itself, here and there.
