Defined in:

Overview

This class defines a single criterion used in advanced searches and smart groups throughout the JSS module.

They are used within Criteria instances which store an array of these objects and provides methods for working with them as a group.

The classes that mix-in Jamf::Criteriable each have a :criteria attribute which holds one Criteria

See Jamf::Criteriable for examples

Constructor Details

#initialize(**args) ⇒ Criterion

Note:

:priority is maintained by the Jamf::Criteriable::Criteria object holding this instance

Returns a new instance of Criterion.

Parameters:

  • args (Hash) —

    a hash of settings for the new criterion

Options Hash (**args):

  • :and_or (String, Symbol) —

    :and, or :or. How should this criterion be join with its predecessor?

  • :name (String) —

    the name of a Criterion as is visible in the JSS webapp.

  • :search_type (String) —

    one of SEARCH_TYPES, the comparison between the stored value and :value

  • :value (String) —

    the value to compare with that stored for :name

Raises:

#rest_xml ⇒ REXML::Element

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Note:

For this class, rest_xml can’t be a private method.

Returns The xml element for the criterion, to be embeded in that of a Criteria instance.

Returns:

  • (REXML::Element) —
