Methods

convertToProtoMessage(Descriptors.Descriptor protoSchema, TableSchema tableSchema, Iterable<Object> jsonArray, boolean ignoreUnknownFields)

public List<DynamicMessage> convertToProtoMessage(Descriptors.Descriptor protoSchema, TableSchema tableSchema, Iterable<Object> jsonArray, boolean ignoreUnknownFields)

Converts Json array to list of Protobuf

Parameters
Name Description
protoSchema Descriptor

the schema of the output Protobuf schems.
tableSchema TableSchema

tha underlying table schema for which Protobuf is being built.
jsonArray Iterable<Object>

the input JSON array converted to Protobuf.
ignoreUnknownFields boolean

flag indicating that the additional fields not present in the output schema should be accepted.
Returns
Type Description
List<DynamicMessage>

Converted message in Protobuf format.

convertToProtoMessage(Descriptors.Descriptor protoSchema, TableSchema tableSchema, Object json, boolean ignoreUnknownFields)

public DynamicMessage convertToProtoMessage(Descriptors.Descriptor protoSchema, TableSchema tableSchema, Object json, boolean ignoreUnknownFields)

Converts input message to Protobuf.

WARNING: it's much more efficient to call the other APIs accepting json array if the jsons share the same table schema.

Parameters
Name Description
protoSchema Descriptor

the schema of the output Protobuf schems.
tableSchema TableSchema

tha underlying table schema for which Protobuf is being built.
json Object

the input JSON object converted to Protobuf.
ignoreUnknownFields boolean

flag indicating that the additional fields not present in the output schema should be accepted.
Returns
Type Description
DynamicMessage

Converted message in Protobuf format.

convertToProtoMessage(Descriptors.Descriptor protoSchema, TableSchema tableSchema, JSONArray jsonArray, boolean ignoreUnknownFields)

public List<DynamicMessage> convertToProtoMessage(Descriptors.Descriptor protoSchema, TableSchema tableSchema, JSONArray jsonArray, boolean ignoreUnknownFields)

Converts Json array to list of protocol buffer messages given the protocol buffer descriptor.

Parameters
Name Description
protoSchema Descriptor
tableSchema TableSchema

bigquery table schema is needed for type conversion of DATETIME, TIME, NUMERIC, BIGNUMERIC
jsonArray org.json.JSONArray
ignoreUnknownFields boolean

allows unknown fields in JSON input to be ignored.
Returns
Type Description
List<DynamicMessage>
Exceptions
Type Description
IllegalArgumentException

when JSON data is not compatible with proto descriptor.
