Class DeduplicatingGatewayProcessorFilter

java.lang.Object
  com.raritantechnologies.searchApp.dataCollection.GatewayProcessorFilter
      com.raritantechnologies.searchApp.dataCollection.DeduplicatingGatewayProcessorFilter

All Implemented Interfaces:

ICollectionIndexer, IConfigurable, IGatewayOutputProcessor, IResultSetProcessor

public class DeduplicatingGatewayProcessorFilter

extends GatewayProcessorFilter

Deduplicates results that pass through the filter based on one or more key field(s) that should have a globally unique value. The filter will remove duplicates for any results that have the same value(s) for the key field(s).

XML Configuration Template:

 <GatewayOutputProcessor class"com.raritantechnologies.searchApp.dataCollection.DeduplicatingGatewayProcessorFilter"
                            keyField="[ field(s) that will have the unique key used to deduplicate ]" >

    <!-- Optional result matcher to filter the result set -->
    <ResultMatcher class="[IResultMatcher class]" >

    </ResultMatcher>

    <!-- One or more Proxy output processor that will get the filtered data set -->
    <OutputProcessor class="[IGatewayOutputProcessor class]" >
      <!-- OutputProcessor details -->
    </OutputProcessor>

    <!-- Additional result set filters that operate on the data after initial processing -->
    <PostProcessor class="[GatewayProcessorFilter class ]" >
      <!-- PostProcessor details -->
    </PostProcessor>
 </GatewayOutputProcessor>
