ExpressionContextFunction
- Scott Cantor
- Rod Widdowson
The bean named shibboleth.ContextFunctions.Expression executes a Spring Expression Language (SpEL) expression to implement a Function operating against a ProfileRequestContext. The underlying net.shibboleth.idp.profile.context.navigate.SpringExpressionContextLookupFunction class can be used if a function operating against a different context class is required.
The Function is instantiated by supplying a string argument that contains a SpEL expression to evaluate.
Example
<bean id="MyPRCFunction" parent="shibboleth.ContextFunctions.Expression"
