dragon.infrastructure.group_desc

A class that uniquely defines properties of a managed Group of resources for infrastructure communication.

Classes

GroupDescriptor

The group descriptor holds a list of tuples of puids, muids, cuids or huids.

class GroupDescriptor[source] 

Bases: object

The group descriptor holds a list of tuples of puids, muids, cuids or huids.

class State[source] 

Bases: IntEnum

Current state of a group’s member.

PENDING = 0

ACTIVE = 1

DEAD = 2

class GroupMember[source] 

Bases: object

The GroupMember class holds information about each object that is a member of the group.

class Errors[source] 

Bases: Enum

SUCCESS = 0: Resource was created

FAIL = 1: Resource was not created

ALREADY = 2: Resource exists already

state: object = None

uid: int = None

placement: int = None

desc: object = None

error_code: int = None

error_info: str = None

classmethod from_sdict(d)[source] 

Returns the launched group member object.

Parameters:: d (Dictionary) – dictionary with all key-value pairs of the available information of the group’s member
Raises:: ValueError – when there is an error during deserialization
Returns:: the GroupMember object
Return type:: GroupMember

get_sdict()[source] 

Collects the entire information of a member of the group.

Returns:: A dictionary with all key-value pairs of the available information of the group’s member.
Return type:: Dictionary

__init__(state: object = None, uid: int = None, placement: int = None, desc: object = None, error_code: int = None, error_info: str = None) → None 

state: State = 0

g_uid: int = None

name: str = None

sets: []

policy: Policy = None

resilient: bool = False

classmethod from_sdict(d)[source] 

Returns the descriptor of the launched group of resources.

Parameters:: d (Dictionary) – dictionary with all key-value pairs of the available information of the group
Raises:: ValueError – when there is an error during deserialization
Returns:: the GroupDescriptor object
Return type:: GroupDescriptor

get_sdict()[source] 

Collects the entire information of the group.

Returns:: A dictionary with all key-value pairs of the available information of the group.
Return type:: Dictionary
