Overview

The ScriptedDataConnector data connector allows the creation of multiple IdPAttribute objects via a JSR-223 script. Scripts are somewhat easier to write and maintain than native Java code, though they are slower. They can also be changed dynamically since the resolver is a ReloadableService.

...

The script "context" defines the execution environment for the script and provides the following variables:

• resolutionContext

  • AttributeResolutionContext for the current resolution step, which exists within the tree of state information that tracks the current request

• connectorResults

  • List which the connector populates with IdPAttribute objects and which form the output of the connector

• profileContext

  • ProfileRequestContext for the current resolution request, the "root" of the tree of state information

• custom

  • Contains whatever bean was referenced by the customObjectRef XML Attribute
    

• subjects

  • Array of Subject objects associated with this request. Note that these will only be present if the attribute resolution is associated with a completed authentication step (so is not present for back channel requests or certain other cases).

In addition, each defined dependency of the connector, it exists, will be present via an object which implements ScriptedIdPAttribute.

...

Note that any changes made to these dependency objects within the script will not be reflected in the result of the resolution process. In contrast, changes made to other objects accessed by means of the other variables in most cases will cause side effects, and should usually be avoided.

Nashorn Scripted Data Connector

<DataConnector id="ScriptedAttributeConnector" xsi:type="ScriptedDataConnector">

attr = new IdPAttribute("TwoScripted");
set = new HashSet(3);

set.add(new StringAttributeValue("2Value"));
set.add(new StringAttributeValue("3Value"));

</DataConnector>

This Rhino example is a hold over from older versions but may be useful in the future once it becomes a supported option again.
