dragon.infrastructure.process_desc
A class that uniquely defines properties of a managed Process for infrastructure communication.
Functions
|
Populate and return the mode of arguments as per the ArgMode |
Classes
Enum for mode of delivering the arguments, either process will be using the channel (or) to deliver the argdata directly |
|
Globally available description of a managed process. |
|
Open type, placeholder, for options on how to launch a process |
- class ArgMode
Enum for mode of delivering the arguments, either process will be using the channel (or) to deliver the argdata directly

- stateProcessDescriptor.State enum member
current run state of this process
stdin_sdesc : a serialized channel where the stdin of the process can be provided.
stdout_sdesc : a serialized channel where the stdout of the process is written.

mode of delivering the arguments, either process will be using the channel (or) to deliver the argdata directly
- make_inf_channels
bool, default False, whether process should start making the infrastructure channels when they are needed, or just start the process directly.
