Simple implementation of the %iKnow.Filters.Filter interface, building a simple equality condition on External ID.
- domainId As %Integer
- externalIds As %List - List of the external IDs that should be included by this filter. Can also be supplied as an array, in which case the top node is ignored.
Subclasses should implement this method to build a string representation of the filter instance. It should start with the filter class name, followed by a pipe (|) character and then a string representation that can be interpreted by its RestoreFilterFromStringInternal implementation.
