label

%<name>.name

no

AD.name

The label to display in a form to configure this property. This name may be localized by prepending a % sign to the name.

description

%<name>.description

no

–

AD.description

A descriptive text to provide the client in a form to configure this property. This name may be localized by prepending a % sign to the name.

propertyPrivate

Depending on the name

no

See description

Boolean flag defining whether a metatype descriptor entry should be generated for this property or not. By default a metatype descriptor entry, i.e. an AD element, is generated except for the properties service.pid, service.description, service.id, service.ranking, service.vendor, service.bundlelocation and service.factoryPid. If a property should not be available for display in a configuration user interface, this parameter should be set to true.

cardinality

Depends on property value(s)

no

–

AD.cardinality

Defines the cardinality of the property and its collection type. If the cardinality is negative, the property is expected to be stored in a java.util.Vector (primitive types such as boolean are boxed in the Wrapper class), if the cardinality is positive, the property is stored in an array (primitve types are unboxed, that is Boolean type values are stored in boolean[]). The actual value defines the maximum number of elements in the vector or array, where Integer.MIN_INT describes an unbounded Vector and Integer.MAX_INT describes an unbounded array. If the cardinality is zero, the property is a scalar value. If the defined value of the property is set in the value attribute, the cardinality defaults to 0 (zero for scalar value). If the property is defined in one or more properties starting with values, the cardinality defaults to Integer.MAX_INT, that is an unbounded array. ]]></ac:plain-text-body></ac:structured-macro>
