}

Port Types​

Each port has a type, that defines the type of data that can be passed through it. The following basic types are supported:

  • int
  • float
  • string
  • boolean
  • structure

Additionality there are some special types:

  • List - A list of values of the same type
  • Dict - A key-value pair of values of the same type
  • Union - A value that can be one of multiple types

Importantly Ports always specifie if they expect nullable values or not.

note

Structure Ports are a bit special. They are used to define non serializable data structures, that need to be shrank down to a serializable format, and expanded back to the original format, when passing from one app to another app.
