gravitino.dto.function.function_definition_dto.FunctionDefinitionDTO¶

class gravitino.dto.function.function_definition_dto.FunctionDefinitionDTO(_parameters: List[FunctionParamDTO] | None = None, _return_type: Type | None = None, _return_columns: List[FunctionColumnDTO] | None = None, _impls: List[FunctionImplDTO] | None = None)¶

Bases: FunctionDefinition, DataClassJsonMixin

DTO for function definition.

__init__(_parameters: List[FunctionParamDTO] | None = None, _return_type: Type | None = None, _return_columns: List[FunctionColumnDTO] | None = None, _impls: List[FunctionImplDTO] | None = None) → None¶
