dragon.infrastructure.channel_desc

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

Classes

`ChannelDescriptor`	Globally available description of a managed channel.
`ChannelOptions`	Open type, placeholder, for options on how to make a channel

class ChannelDescriptor[source] 

Bases: object

Globally available description of a managed channel.

Attributes:

nodenonnegative int
which node this channel

namestr
user assigned unique name of the process

c_uidnonnegative int
unique channel id

m_uidnonnegative int
memory pool containing this channel

sdescbytes-like object
serialized descriptor from the Channels library

statecls.State enum member
current run state of this process

class State[source] 

Bases: Enum

Current state of the channel.

PENDING = 1

ACTIVE = 2

DEAD = 3

__init__(m_uid, c_uid, name, node, state=None, sdesc='')[source] : sdesc - serialized library descriptor

property sdesc: Returns the serialized library descriptor of the channel.

get_sdict()[source] 

Collect the entire information of the channel.

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

classmethod from_sdict(sdict)[source] : Returns the descriptor of the managed channel.

class ChannelOptions[source] 

Bases: object

Open type, placeholder, for options on how to make a channel

Attributes:

local_opts

local channel creation options, such as block size and capacity. see dragon.localservices.options.ChannelOptions

ref_count

bool, default False, whether GS should count references on this channel and destroy if count reaches zero

NOTE: these options will be growing and the scheme needs thought for organization.

__init__(*, local_opts=None, ref_count=False)[source] 

get_sdict()[source] 

Collect the different attributes/options of the channel.

Returns:: A dictionary with key-value pairs of the channel options.
Return type:: Dictionary

static from_sdict(sdict)[source] : Returns the options of the managed channel.
