Class SimpleAttributePredicate

java.lang.Object

net.shibboleth.idp.profile.logic.SimpleAttributePredicate

All Implemented Interfaces:

com.google.common.base.Predicate<org.opensaml.profile.context.ProfileRequestContext>

public class SimpleAttributePredicate
extends Object
implements com.google.common.base.Predicate<org.opensaml.profile.context.ProfileRequestContext>

Predicate that evaluates an AttributeContext and checks for particular attribute/value pairs.

A map to a collection of strings is used to represent the attribute(s) and value(s) to evaluate. The values are evaluated as a disjunction (OR) and the attributes are evaluated as a conjunction (AND).

This handles only simple string-valued data.

For the special case of checking for an attribute's presence, regardless of values, the '*' value is supported.
