This is a MEF component part, and should be imported as follows:

[Import] 
IViewClassifierAggregatorService aggregator = null;

The normalized classifications produced by this aggregator are sorted and do not overlap. If a span of text has multiple classifications, based on the original classifier contributions, then in the normalized classification it has a transient classification IClassificationTypeRegistryService that corresponds to all of the original classifications

Classifier aggregators are cached for each combination of ITextBuffer and ITextView.

For more information about classification, see the section "Extending Classification Types and Classification Formats" in Editor Extension Points.
