◆ add_incompatibility() [1/2]

void Compatibility_module::add_incompatibility ( Member_version from,
Member_version to 
)

Add a incompatibility between the given members.

Parameters
fromThe member that is not compatible with 'to'
toThe member with which 'from' is not compatible with

◆ add_incompatibility() [2/2]

void Compatibility_module::add_incompatibility ( Member_version from,
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'
to_minThe minimum version with which 'from' is not compatible with
to_maxThe maximum version with which 'from' is not compatible with

◆ check_incompatibility()

Compatibility_type Compatibility_module::check_incompatibility ( Member_version from,
Member_version to,
bool  do_version_check,
const std::set< Member_version > &  all_members_versions 
)

Checks if the given version is incompatible with another version.

Parameters
fromThe member that may be not compatible with 'to'
toThe member with which 'from' may be not compatible with
do_version_checkIf version compatibility check is needed

Returns
the compatibility status
Return values
INCOMPATIBLEThe versions are not compatible with each other
COMPATIBLEThe versions are compatible with each other
READ_COMPATIBLEThe version 'from' can only read from 'to'

We have already confirmed versions are not same. If joinee version is higher then group lowest version, its read compatible else joinee version is INCOMPATIBLE with the group.
