Submodules¶

keystone.limit.backends.base module¶

class keystone.limit.backends.base.UnifiedLimitDriverBase[source]¶

Bases: object

create_limits(limits)[source]¶

Create new limits.

Parameters:	limits – a list of dictionaries representing limits to create.
Returns:	all the limits.
Raises:	keystone.exception.Conflict – If a duplicate limit exists. keystone.exception.NoLimitReference – If no reference registered limit exists.

create_registered_limits(registered_limits)[source]¶

Create new registered limits.

Parameters:	registered_limits – a list of dictionaries representing limits to create.
Returns:	all the registered limits.

delete_limit(limit_id)[source]¶

Delete an existing limit.

Parameters:	limit_id – the limit id to delete.
Raises:	keystone.exception.LimitNotFound – If limit doesn’t exist.

delete_registered_limit(registered_limit_id)[source]¶

Delete an existing registered limit.

Parameters:	registered_limit_id – the registered limit id to delete.
Raises:	keystone.exception.RegisteredLimitNotFound – If registered limit doesn’t exist.

get_limit(limit_id)[source]¶

Get a limit.

Parameters:	limit_id – the limit id to get.
Returns:	a dictionary representing a limit reference.

get_registered_limit(registered_limit_id)[source]¶

Get a registered limit.

Parameters:	registered_limit_id – the registered limit id to get.

list_limits(hints)[source]¶

List all limits.

Parameters:	hints – contains the list of filters yet to be satisfied. Any filters satisfied here will be removed so that the caller will know if any filters remain.
Returns:	a list of dictionaries or an empty list.

list_registered_limits(hints)[source]¶

update_registered_limits(registered_limits)[source]¶

Update existing registered limits.

Parameters:	registered_limits – a list of dictionaries representing limits to update.
Returns:	all the registered limits.
Raises:	keystone.exception.RegisteredLimitNotFound – If registered limit doesn’t exist. keystone.exception.Conflict – If update to a duplicate registered limit.
