ExpressionPredicate

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()" />

Reference

The following additional bean properties are available:

Name	Type	Default	Description

Name	Type	Default	Description
customObject	Bean/Reference		An object to make available to the script via a variable named `custom`
returnOnError	boolean	false	What to return if the expression fails
hideExceptions	boolean	false	If true, then the `returnOnError` value is returned if the expression raises an exception, otherwise the exception is passed out

The expression context will have two variables populated:

input - the ProfileRequestContext being evaluated
custom - the object set via the customObject property, if any
