Examples of RecordComparatorFactory

eu.stratosphere.api.java.typeutils.runtime.record.RecordComparatorFactory
A factory for a {@link TypeComparator} for {@link Record}. The comparator uses a subset of the fields for the comparison. That subset of fields (positions and types) is read from the supplied configuration.
org.apache.flink.api.common.typeutils.record.RecordComparatorFactory
A factory for a {@link org.apache.flink.api.common.typeutils.TypeComparator} for {@link Record}. The comparator uses a subset of the fields for the comparison. That subset of fields (positions and types) is read from the supplied configuration.
