Declaring Input and Output Ports

Declare Input Ports with i_MyVar and Output Ports with o_MyVar.

Input and Output Ports Data Types

There are five types of Input/Output ports:

• String
• Integer
• Double
• Long
• Boolean

Examples:

• ib_myBooleanInput would be an Input Port with Boolean data type.
• os_myStringOutput would be an Output Port with String data type.

Default Functions

By default there are three functions:

• Startup: is executed once when the JavaScript Unit is triggered after the Project is set into running state.
• Shutdown: is executed when Workflow stops executing (e.g. when the Project stops).
• Execute: is executed when the JavaScript Unit is triggered.

Using Project Variables

Project Variables can be used globally in certain Units (JavaScript, Shell Command). To use a Project Variable, enclose the Variable name in '$', for example "$myVariable$".
