Class
    Foam::substitutionModels::fileRegEx
 
Description
    The \c fileRegEx substitution model.
 
    The example below shows how the keyword \c executionTime is set by
    applying a regular expression (string) to a log file.
 
    \verbatim
    fileRegEx1
    {
        // Mandatory entries
        type        fileRegEx;
        path        "log.simpleFoam";
 
        entries
        {
            executionTime    "ExecutionTime = (.*) s  Clock.*";
        }
 
        // Optional entries
        sectionSeparator    <string>;
        matchSeparator      <string>;
        lastMatch           <bool>;
 
        // Inherited entries
        ...
    }
    \endverbatim
 
    The entries mean:
    \table
      Property     | Description                        | Type | Reqd  | Deflt
      type         | Type name: functionObjectValue     | word |  yes  | -
      path         | Path to file                       | string |  yes  | -
      entries      | Keyword regular-expression pairs   | dictionary | yes | -
      sectionSeparator | Marker used to separate files into sections  <!--
            --!>   | string | no | "Time ="
      matchSeparator | Separator used to join multiple values <!--
            --!>   | string | no | " "
      lastMatch    | Flag to use last file section      | bool | no    | yes
    \endtable
 
    The inherited entries are elaborated in:
