CEWS Pipeline Toolkit - MetaDataInjectorSuffixTree

MetaDataInjectorSuffixTree

This stage performs dictionary lookups on input fields and populates the output fields with all the matched values. This is similar to MetaDataInjector, except that it uses a SuffixTree which is more efficient in handling large numbers of triggers vs. sequential string comparison so it only supports “equals” matches.
