%iKnow.Filters.SimpleMetadataFilter
class %iKnow.Filters.SimpleMetadataFilter extends %iKnow.Filters.Filter
Filter implementation selecting sources based on their metadata values, as set through %iKnow.Queries.MetadataAPI.
Filter parameters:
- domainId As %Integer
- fieldName As %String - the name of the metadata field to filter by.
- filterOperator As %String - the operator to use for filtering (should be a supported one for this metadata field).
- filterValue - the value to compare the actual source metadata values against.

If this method returns an error then the object will not be created.
It is passed the arguments provided in the %New call. When customizing this method, override the arguments with whatever variables and types you expect to receive from %New(). For example, if you're going to call %New, passing 2 arguments, %OnNew's signature could be:
Method %OnNew(dob as %Date = "", name as %Name = "") as %Status If instead of returning a %Status code this returns an oref and this oref is a subclass of the current class then this oref will be the one returned to the caller of %New method.
This is the primary method that needs to be implemented by an actual %iKnow.Filters.Filter subclass to translate the abstract filter criteria the subclass addresses into a bitstring based on Source IDs. The subclass' implementation of this method should use SetSourceBits() for this purpose, setting the requested bitstrings for each offset up to maxOffset.
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.
