Connectors

Connectors connect data and values to tools. The connector arrows show the direction of processing.

There are four types of connectors: Data, Environment, Precondition, and Feedback.

	Data connector—connects data and value variables to tools.
	Environment connector—connects a variable containing an environment setting (data or value) to a tool.
	Precondition connector—a connection from a variable to a tool. The tool will execute only when the contents of the precondition variable are current.
	Feedback connector—the output of a tool will be fed back into the same tool as input.
