The most important use of Predicates is in ActivationConditions, and the majority of the predefined beans are of this type.   They implement  Predicate<ProfileRequestContext>, and will be .  In the role of ActivationConditions they are called with the current Request context (when provided as a activation condition.

• shibboleth.Conditions.BrowserProfile - return TRUE if the current profile is one which assumes browser interaction.
• shibboleth.Conditions.RelyingPartyId  - return TRUE based on the EntityID of the relying party,
• shibboleth.Conditions.Scripted
• shibboleth.Conditions.Expression

• shibboleth.Conditions.Predicate
• shibboleth.Conditions.EntityDescriptor
• shibboleth.Conditions.SubjectName
• shibboleth.Conditions.AllowedSAMLPresenters
• shibboleth.Conditions.IssuingDelegatedAssertion


Attribute Predicates

These class of predicates default to being an ActivationCondition (although complex configuration allow this to be changed).  Their task is to make a decision based on any attributes that have been resolved (so far).  All variants allow for either the filtered or unfiltered attributes to be consulted.  Obviously these predicates are only valid after attribute resolution has taken place.

None of these Predicates have names and so their FQ java class name has to be used.

• net.shibboleth.idp.profile.logic.DateAttributePredicate - returns TRUE if the content of the provided attribute parses to a date which is later that the current time
  
• net.shibboleth.idp.profile.logic.SimpleAttributePredicate - Matches the (all the) attributes' values against a lookup table (AttributeName, value)
  
• net.shibboleth.idp.profile.logic.RegexAttributePredicate - applies a regularg expression against the values of a specified attibute
• net.shibboleth.idp.profile.logic.DynamicAttributePredicate
