Class MapQueryResultsHandler

java.lang.Object

org.protempa.dest.AbstractQueryResultsHandler

org.protempa.dest.map.MapQueryResultsHandler

All Implemented Interfaces:

AutoCloseable, QueryResultsHandler

public final class MapQueryResultsHandler
extends AbstractQueryResultsHandler

An implementation of QueryResultsHandler that stores the results in a map that may be accessed later for post-processing. As each call to handleQueryResult is made, each key-proposition list argument pair is added to the map.
