Block

Description

A container paradigm component.

The execution order and number of repetitions of a block’s sub-components are determined by selection, nsamples, and sampling_method.

Signature

block

Optional Parameters

interruptible

Default

YES

If NO, then any request to pause or stop the experiment while this component is executing will be deferred until said execution completes. This behavior is inherited by the component’s children, making them non-interruptible as well.
