Enum Class ComparisonJoinKey.SimpleComparisonType

java.lang.Object
java.lang.Enum<ComparisonJoinKey.SimpleComparisonType>
io.substrait.proto.ComparisonJoinKey.SimpleComparisonType
All Implemented Interfaces:
com.google.protobuf.Internal.EnumLite, com.google.protobuf.ProtocolMessageEnum, Serializable, Comparable<ComparisonJoinKey.SimpleComparisonType>, Constable
Enclosing class:
ComparisonJoinKey
public static enum ComparisonJoinKey.SimpleComparisonType extends Enum<ComparisonJoinKey.SimpleComparisonType> implements com.google.protobuf.ProtocolMessageEnum
 Most joins will use one of the following behaviors.  To avoid the complexity
 of a function lookup we define the common behaviors here
Protobuf enum substrait.ComparisonJoinKey.SimpleComparisonType
