Class StructuredRelDataType

java.lang.Object
org.apache.calcite.rel.type.RelDataTypeImpl
org.apache.calcite.sql.type.AbstractSqlType
org.apache.calcite.sql.type.ObjectSqlType
org.apache.flink.table.planner.plan.schema.StructuredRelDataType
All Implemented Interfaces:
Serializable, Cloneable, org.apache.calcite.rel.type.RelDataType, org.apache.calcite.rel.type.RelDataTypeFamily
@Internal public final class StructuredRelDataType extends org.apache.calcite.sql.type.ObjectSqlType
The RelDataType representation of a StructuredType.

It extends ObjectSqlType for preserving the original logical type (including an optional implementation class) and supporting anonymous/unregistered structured types from Table API.
