Method Detail

fromTyped

static <T> ChildWorkflowStub fromTyped(T typed)

Extracts untyped WorkflowStub from a typed workflow stub created through Workflow.newChildWorkflowStub(Class).

Type Parameters:

T - type of the workflow stub interface

Parameters:

typed - typed workflow stub

Returns:

untyped workflow stub for the same workflow instance.

getExecution

Promise<io.temporal.api.common.v1.WorkflowExecution> getExecution()

Returns promise that becomes ready once the child has started. If workflow completes before this promise is ready then the child might not start at all.

getOptions
