[lmi-commits] [lmi] master 25a989e 10/46: Make table_type_converter::get_all() map const

[Greg Chicares]

branch: master
commit 25a989ef472a799b8f1ffbb5dc167f55b1d35bb2
Author: Vadim Zeitlin <vadim@tt-solutions.com>
Commit: Vadim Zeitlin <vadim@tt-solutions.com>

    Make table_type_converter::get_all() map const
    
    This map collects all type converters defined at compilation time and
    never changes, so it should be const.
