Using the Delete mode

The most common and simple pattern for using a Connector in Delete mode is:

1. Using the Config Editor, add a Connector in Delete mode to our workspace. See Creating a Connector.

2. Set the mode (Delete) and other connection parameters for this Connector in the Connection tab; required parameters are marked with an asterisk (*). Some Connectors require you to configure a Parser as well in the Parser tab.

3. Set up the Attribute Map; see Input Attribute mapping.

4. In the Input Attribute Map tab we can select attributes from the Connector Attribute list and then drag them into our Input Map. We can also add and remove attributes manually.

   The Input Map is used in Delete mode for reading the matching entry found in the data source into the conn entry object, which can then be used in your scripts (for example, to determine if the entry actually is to be deleted).

5. Open the Link Criteria tab on the Connector configuration window and set up the rules for attribute matching. The outcome of this process will determine which entries are retrieved from the connected system, and here we have a couple of choices:

   1. Click Add to add a new Link Criterion and select an attribute from the connected system, the matching operator (for example, Equals, Begins With, and so forth) and then the Work Entry attribute to be matched. When the Connector performs the Lookup, it creates the underlying API or protocol syntax based on the Link Criteria we have specified, keeping the solution independent of the type of system used. We can add multiple Link Criteria, which are connected by the Boolean operator AND, together to build the search call.

   2. We can also select Build criteria with custom script, which opens a script editor window where we can create our own search string, passing this back to the Connector using the ret.filter object. For example:

      ret.filter = "uid=" + work.getString("uid");

   See Link Criteria for more information about Link Criteria.

If you did not create the Connector directly inside an AssemblyLine, then to use the Connector in an AssemblyLine, drag it from its location in <workspace>/Resources/Connectors to the Flow section of the AssemblyLine.
