java.lang.Object

org.apache.flink.api.common.typeutils.TypeComparator<CharValueArray>

org.apache.flink.graph.types.valuearray.CharValueArrayComparator

All Implemented Interfaces:

Serializable

@Internal
public class CharValueArrayComparator
extends org.apache.flink.api.common.typeutils.TypeComparator<CharValueArray>
