Interface ExtendedRelTypeFactory

  • All Superinterfaces:
    org.apache.calcite.rel.type.RelDataTypeFactory
    @Internal
public interface ExtendedRelTypeFactory
extends org.apache.calcite.rel.type.RelDataTypeFactory
    A factory for creating RelDataType instances including Flink-specific extensions.

    This interface exists because the parser module has no access to the planner's type factory.
