Member Function Documentation

add_incompatibility() [1/2]

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

Add a incompatibility between the given members.

Parameters

from	The member that is not compatible with 'to'
to	The 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

from	The member that is not compatible with 'to'
to_min	The minimum version with which 'from' is not compatible with
to_max	The 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
	)

Checks if the given version is incompatible with another version.

Parameters

from	The member that may be not compatible with 'to'
to	The member with which 'from' may be not compatible with
do_version_check	If version compatibility check is needed

Returns

the compatibility status

Return values

INCOMPATIBLE	The versions are not compatible with each other
COMPATIBLE	The versions are compatible with each other
READ_COMPATIBLE	The 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.

check_local_incompatibility()

Compatibility_type Compatibility_module::check_local_incompatibility	(	Member_version &	to,
		bool	is_lowest_version
	)

Checks if the given version is compatible with this member local version.

Parameters

to	The member with which 'from' may be not compatible with
is_lowest_version	If to version is lowest in the group

Returns

the compatibility status

Return values

INCOMPATIBLE	The versions are not compatible with each other
COMPATIBLE	The versions are compatible with each other
READ_COMPATIBLE	The version 'from' can only read from 'to'

check_version_incompatibility()

Compatibility_type Compatibility_module::check_version_incompatibility ( Member_version  from, Member_version  to  )

static

Checks if the given version is incompatible with another version.

Parameters

from	The member that may be not compatible with 'to'
to	The member with which 'from' may be not compatible with

Returns

the compatibility status

Return values

INCOMPATIBLE	The versions are not compatible with each other
COMPATIBLE	The versions are compatible with each other
READ_COMPATIBLE	The version 'from' can only read from 'to'

check_version_range_incompatibility()

bool Compatibility_module::check_version_range_incompatibility	(	Member_version &	from,
		unsigned int	to_min,
		unsigned int	to_max
	)

Checks if the given version is incompatible with another version.

Parameters

from	The member that may be not compatible with 'to'
to_min	The minimum version with which 'from' is not compatible with
to_max	The maximum version with which 'from' is not compatible with

Returns

the compatibility status

Return values

false	The version is not in the range of the incompatible versions
