core:Cardinality
Ensure the number of attribute values is within the specified multiplicity.
This filter should contain a set of attribute name => rule pairs describing the multiplicity rules for an attribute.
The special parameter
%ignoreEntities
can be used to give an array of entity IDs that should be ignored for testing, etc purposes.
A separate
core:CardinalitySingle
authproc filter provides additional functionality for the special case where attributes are single valued.
Specifying Rules
Multiplicity rules are specified as an associative array containing one or more of the following parameters:
-
min
-
The minimum number of values (participation) this attribute should have. Defaults to
zero
. -
max
- The maximum number of values (cardinality) this attribute should have. Defaults to no upper bound.
-
warn
-
Log a warning rather than generating an error. Defaults to
false
.
For convenience, minimum and maximum values can also be specified using a shorthand list notation.
Examples
Require at least one
givenName
, no more than two email addresses, and between two and four values for
eduPersonScopedAffiliation
.
'authproc' => array(
50 => array(
'class' => 'core:Cardinality',
'givenName' => array('min' => 1),
'mail' => array('max' => 2),
'eduPersonScopedAffiliation' => array('min' => 2, 'max' => 4),
),
),
Use the shorthand notation for min, max:
'authproc' => array(
50 => array(
'class' => 'core:Cardinality',
'mail' => array(0, 2),
),
),
