  • Method Details

    • of

      public static BridgingSqlAggFunction of(org.apache.flink.table.catalog.DataTypeFactory dataTypeFactory, FlinkTypeFactory typeFactory, org.apache.calcite.sql.SqlKind kind, org.apache.flink.table.catalog.ContextResolvedFunction resolvedFunction, org.apache.flink.table.types.inference.TypeInference typeInference)
      Creates an instance of a aggregating function (either a system or user-defined function).
      Parameters:
      dataTypeFactory - used for creating DataType
      typeFactory - used for bridging to RelDataType
      kind - commonly used SQL standard function; use SqlKind.OTHER_FUNCTION if this function cannot be mapped to a common function kind.
      resolvedFunction - system or user-defined FunctionDefinition with context
      typeInference - type inference logic
