Creating Workflow Stubs

The Infinitic client manages workflows through stubs built from the workflow interface.

Here is an example of workflow interface from our Hello World app:

Using this interface, an Infinitic client can create stubs that behaves syntactically as instances of such workflow. Stubs are used to trigger actions such as:

  • starting a new workflow
  • cancelling running workflows
  • sending a signal to running workflows
  • starting a new method on running workflows

Stub of new workflow

The client has a newWorkflow method to create the stub of a new workflow:

We can also add tags to this stub. Those tags will be attached to workflow instances started with this stub.

The stub of new workflow can be used to start a new workflow instance. It can be used multiple times to start multiple instances.

Running workflow stub

A workflow is said running, as long as it is neither completed neither canceled.

We can create the stub of a running workflow from its id:

Alternatively, we can create a stub targeting all running workflow having a given tag:

The stub of running workflows can be used to apply actions to the targeted workflows:

  • cancelling
  • sending signals
  • starting new methods

Creating a stub has no side effect. It just creates an object that contains the provided info.
