jina.types.mixin module#

class jina.types.mixin.ProtoTypeMixin[source]#

Bases: object

The base mixin class of all Jina types.

Note

All Jina types should inherit from this class.
All subclass should have self._pb_body

All subclass should implement __init__ with the possibility of initializing from None, e.g.:

class MyJinaType(ProtoTypeMixin):

    def __init__(self, proto: Optional[jina_pb2.SomePbMsg] = None):
        self._pb_body = proto or jina_pb2.SomePbMsg()

to_json()[source]#

Return the object in JSON string

Return type: str
Returns: JSON string of the object

to_dict()[source]#

Return the object in Python dictionary.

Note

Array like object such as numpy.ndarray (i.e. anything described as jina_pb2.NdArrayProto) will be converted to Python list.

Return type: Dict
Returns: dict representation of the object

property proto: jina_pb2._reflection.GeneratedProtocolMessageType#

Return the underlying Protobuf object

Return type: jina_pb2._reflection.GeneratedProtocolMessageType
Returns: Protobuf representation of the object

to_bytes()[source]#

Return the serialized the message to a string.

For more Pythonic code, please use bytes(...).

Return type: bytes
Returns: binary string representation of the object

property nbytes: int#

Return total bytes consumed by protobuf.

Return type: int
Returns: number of bytes
