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:
    \param merge      merge sub-dictionaries when possible
    \param overwrite  keep last entry and silently remove previous ones
    \param protect    keep initial entry and silently ignore subsequent ones
    \param warn       keep initial entry and warn about subsequent ones
    \param error      issue a FatalError for duplicate entries
    \param default    currently identical to merge
