Class
    Foam::functionEntries::inputModeEntry
 
Description
    Specify the input mode when reading dictionaries, expects
    a single word to follow.
 
    An example of \c \#inputMode directive:
    \verbatim
        #inputMode merge
    \endverbatim
 
    The possible input modes:
      - \par merge      merge sub-dictionaries when possible
      - \par overwrite  keep last entry and silently remove previous ones
      - \par protect    keep initial entry and silently ignore subsequent ones
      - \par warn       keep initial entry and warn about subsequent ones
      - \par error      issue a FatalError for duplicate entries
      - \par default    currently identical to merge
