Class
    Foam::substitutionModels::functionObjectValue
 
Description
    functionObjectValue substitution model.
 
Usage
    The \c functionObjectValue substitution model.
 
    The example below shows how the keywords \c cont_error_* are set by
    retrieving the values \c local, \c global, \c cumulative from the function
    object \c functionObjectValue.
 
    \verbatim
    functionObjectValue1
    {
        // Mandatory entries
        type        functionObjectValue;
        functionObject continuityError1;
 
        entries
        {
            cont_error_local    local;
            cont_error_global   global;
            cont_error_cumulative cumulative;
        }
 
        // Optional entries
        debugValues   <bool>;
 
        // Inherited entries
        ...
    }
    \endverbatim
 
    The entries mean:
    \table
      Property     | Description                        | Type | Reqd  | Deflt
      type         | Type name: functionObjectValue     | word |  yes  | -
      functionObject | Name of function object to query | word |  yes  | -
      entries      | Keyword-lookup pairs               | dictionary | yes | -
      debugValues  | Flag to show available function values | bool | no | false
    \endtable
 
    The inherited entries are elaborated in:
