Member_version to_min,
Member_version to_max 
)

Add a incompatibility between a range of member versions.

Parameters
fromThe member that is not compatible with 'to'

◆ check_incompatibility()

Compatibility_type Compatibility_module::check_incompatibility ( Member_version from,
Member_version to,
bool  do_version_check 
)

Checks if the given version is incompatible with another version.

Parameters
fromThe member that may be not compatible with 'to'
