Connector modes

Connector modes

The mode of an AssemblyLine Connector defines what role that Connector plays in the data flow, and controls how the automated behavior of the AssemblyLine drives the Component. It determines whether to read from an input source, write to it or both. Connectors can be set to one of these standard modes:

Connector Mode Description
Iterator Scan a data source and extract its data. The Connector in Iterator mode actually iterates through the data source entries, reads their attribute values, and delivers each entry to the AssemblyLine Flow section components, one at a time. A Connector in Iterator mode is commonly referred to as an Iterator Connector, or just Iterator.
Lookup Join data from different data sources using the relationship between attributes in these systems. A Connector in Lookup mode is often referred to as a Lookup Connector.
AddOnly Used for adding new data entries to a data source.
Update Used for adding and modifying data in a data source. For each entry passed from the AssemblyLine, the Update Connector tries to locate a matching entry from the data source to modify with the values of the entry attributes received. If no match is found, the Update mode Connector will add a new entry.
Delete Used for deleting data from a data source.
CallReply Make requests to data source services, such as Web services, that require you to send input parameters and receive a reply with return values.
Server Provides the functionality of waiting for an incoming event, dispatch a thread dealing with the event, and send a reply back to the originator.
Delta Simplify the application of changes to data by providing incremental modifications to the connected system, based on delta operation codes.
Link Criteria
Tell a Connector in Update, Lookup and Delete modes how to define a match between data attributes in the AssemblyLine and those found in the connected system.

Connector Mode	Description
Iterator	Scan a data source and extract its data. The Connector in Iterator mode actually iterates through the data source entries, reads their attribute values, and delivers each entry to the AssemblyLine Flow section components, one at a time. A Connector in Iterator mode is commonly referred to as an Iterator Connector, or just Iterator.
Lookup	Join data from different data sources using the relationship between attributes in these systems. A Connector in Lookup mode is often referred to as a Lookup Connector.
AddOnly	Used for adding new data entries to a data source.
Update	Used for adding and modifying data in a data source. For each entry passed from the AssemblyLine, the Update Connector tries to locate a matching entry from the data source to modify with the values of the entry attributes received. If no match is found, the Update mode Connector will add a new entry.
Delete	Used for deleting data from a data source.
CallReply	Make requests to data source services, such as Web services, that require you to send input parameters and receive a reply with return values.
Server	Provides the functionality of waiting for an incoming event, dispatch a thread dealing with the event, and send a reply back to the originator.
Delta	Simplify the application of changes to data by providing incremental modifications to the connected system, based on delta operation codes.
Link Criteria	Tell a Connector in Update, Lookup and Delete modes how to define a match between data attributes in the AssemblyLine and those found in the connected system.
