Parameter connections enable you to provide a parameter value to another connection. If a connection is shown as a dotted line, it requires one or more parameters.
There are three types of Parameter connections:
Parameter-from-attribute connections use the value of an attribute as the parameter to a connection.
Parameter-from-script connections run a script whenever a parameter to a connection is required. This connection is much the same as a parameter-from-attribute connection except that the value supplied to the connection is returned from a Smalltalk script instead of a part attribute value.
Parameter-from-action connections use the result of an action as a parameter to a connection.
The connection is, by default, a purple line with a large dot at one end and a hollow dot with a square in it at the other end.
