If step

This step allows for conditional branching of the protocol.

The condition can contain anything, including variables and channels, and works like conditions in python. This is similar to the While Loop or waiting for a condition.

A grayed sub-step will appear in the protocol, called “If_Sub”. The steps to be executed when the condition is true go here. When Use Else is selected, analogously an “Else_Sub” will appear to be executed when the condition is false.

In between the “If_Sub” and “Else_Sub”, or without “else”, an arbitrary number of “Elif” cases can be inserted. They may check for other conditions, allowing for simple branching on several conditions without nesting many If-steps.

When “End protocol if condition is true” is selected, the protocol will stop after the execution of the steps in “If_Sub”. However, “If_Sub” may also be empty in this case.
