org.apache.calcite.sql.type.AbstractSqlType

org.apache.calcite.sql.type.ObjectSqlType

org.apache.flink.table.planner.plan.schema.StructuredRelDataType

所有已实现的接口:

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.
