The predicate bean named shibboleth.Conditions.Expression executes a Spring Expression Language (SpEL) expression against a ProfileRequestContext to produce a true/false result.

An Expression Predicate is instantiated by simply supplying a string argument that contains a SpEL expression.

Example

<bean id="MyCondition" parent="shibboleth.Conditions.Expression" c:expression="#input.isBrowserProfile()" />
