# CollectionStatsPolicyConstraintType (Complex Type)

### Namespace: http://midpoint.evolveum.com/xml/ns/public/common/common-3

Supertype: AbstractPolicyConstraintType

Constraints for collection stats (statistics). Can be used to trigger policy rules on the number of objects in collection, percentage and so on.

Policy rules with this constraint are ignored during normal processing. Evaluation of such policy rules require special handling (e.g. scanner task).

  - #### name

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Display order:

    Identifier of the constraint. It is used when midPoint needs to refer to a specific constraint, e.g. in order to record exception. This element is formally specified as optional, mostly due to the compatibility reasons. But it has to be provided in order for some functionality to work correctly.

  - #### description

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Display order:

  - #### documentation

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Display order:

    Technical documentation for a particular object or construct.

    The purpose of this element is to document system configuration and behavior. The documentation will not be presented to end users. In fact, it will probably not be presented at all in midPoint user interface. This documentation element is supposed to be a part of the technical documentation of midPoint deployment. The tools than generate deployment configuration will look for these elements and combine them to compiled documentation document.

    AsciiDoc formatting is assumed for this element. Any leading or trailing whitespace is skipped. Indentation equivalent to he indentation of the first non-blank line of text is also skipped.

  - #### presentation

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Display order:

    How should be triggering of this constraint presented, e.g. in enforcement messages, in approvals, in certification, in notifications, etc.

  - #### collection

    Flags: RAM,runtime

    Multiplicity: [0,-1]

    Display order:

    Refers to "itself" as a collection. This means that it interprets the object to which the rule applies as a collection. And this element specifies the details how the collection should be interpreted. E.g. whether we mean the list of objects that ObjectCollectionType refers to by filter. Or whether we mean assignees (owners/approvers) of that object.
