Connectors vs JavaDelegate

Hello there,

What would be advantage/disadvantage to use Connector or JavaDelegate? Which criteria should I consider?

Best regards
Roman

Not much.

Connector is just another abstraction with further encapsulated variable scopes.

I think the general direction is to use a Delegate over creating a custom connector.

You can then use Input Variables for all of the configurations.

here is a example of a delegate with configurable input variables using Optionals
