blivet.populator.helpers.populatorhelper module

class blivet.populator.helpers.populatorhelper.PopulatorHelper(devicetree, data, device=None)

Bases: object

Class to hold type-specific code for populating the devicetree.

:param DeviceTree devicetree: the calling devicetree :param pyudev.Device data: udev data describing a device :keyword device: device instance corresponding to the udev data :type device: StorageDevice

Higher priority value gets checked for match first.

run()

Run type-specific processing.

For device handlers, this method should instantiate the appropriate device type and add the instance to the device tree. For format handlers, this method should instantiate the appropriate format type, associate the instance with the appropriate device, and perform all processing related to the device’s formatting.

update()

Handle changes associated with an event.

This method should handle any changes to an existing format instance. It should not handle reformatting.

Module contents

blivet.populator.helpers.get_device_helper(data)

Return the device helper class appropriate for the specified data.

The helper lists are sorted according to priorities defined within each class. This function returns the first matching class.

blivet.populator.helpers.get_format_helper(data, device)

Return the device helper class appropriate for the specified data.

The helper lists are sorted according to priorities defined within each class. This function returns the first matching class.
