Branch

The Branch is a conditional construct based on the PyFuncApp DROP. It’s main parameters are a function that returns True or False based on requirements for the input data.

Reasons for using the Branch construct include:

• Terminating a Loop when an array is exhausted, before the loop has reache the num_iter parameter. An example of this approach is available on EAGLE.

• Convergence criteria for a value; e.g. leaving a loop once a value is < 0. (Note: this can be acheived using exactly the same pattern, just with an alternative ‘test’ condition.) See an example using EAGLE.
