Class
    Foam::functionObjects::writeDictionary
 
Group
    grpUtilitiesFunctionObjects
 
Description
    Reports dictionary contents on change.
 
Usage
    Minimal example by using \c system/controlDict.functions:
    \verbatim
    writeDictionaryFO
    {
        // Mandatory entries
        type        writeDictionary;
        libs        (utilityFunctionObjects);
        dictNames   <wordList>;
 
        // Inherited entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property     | Description                        | Type | Reqd  | Deflt
      type         | Type name: writeDictionary         | word |  yes  | -
      libs         | Library name: fieldFunctionObjects | word |  yes  | -
      dictNames    | Names of dictionaries to monitor   | wordList |  yes  | -
    \endtable
 
    The inherited entries are elaborated in:
