DataRequest encapsulates the filter for the data, a limit on the maximum results returned, a last string associated with the last returned document, and the sorting order by time. last is returned in the responses TabularDataByFilterResponse and BinaryDataByFilterResponse from the API calls TabularDataByFilter and BinaryDataByFilter, respectively. We can then use the last string from the previous API calls in the subsequent request to get the next set of ordered documents.

Methods

  • Parse from binary data, merging fields.

    Repeated fields are appended. Map entries are added, overwriting existing keys.

    If a message field is already present, it will be merged with the new data.

    Parameters

    • bytes: Uint8Array
    • Optionaloptions: Partial<BinaryReadOptions>

    Returns this

  • Parse a message from a JSON value.

    Parameters

    • jsonValue: JsonValue
    • Optionaloptions: Partial<JsonReadOptions>

    Returns this

  • Parse a message from a JSON string.

    Parameters

    • jsonString: string
    • Optionaloptions: Partial<JsonReadOptions>

    Returns this

  • Retrieve the MessageType of this message - a singleton that represents the protobuf message declaration and provides metadata for reflection- based operations.

    Returns MessageType<DataRequest>

  • Serialize the message to binary data.

    Parameters

    • Optionaloptions: Partial<BinaryWriteOptions>

    Returns Uint8Array

  • Serialize the message to a JSON value, a JavaScript value that can be passed to JSON.stringify().

    Parameters

    • Optionaloptions: Partial<JsonWriteOptions>

    Returns JsonValue

  • Override for serialization behavior. This will be invoked when calling JSON.stringify on this message (i.e. JSON.stringify(msg)).

    Note that this will not serialize google.protobuf.Any with a packed message because the protobuf JSON format specifies that it needs to be unpacked, and this is only possible with a type registry to look up the message type. As a result, attempting to serialize a message with this type will throw an Error.

    This method is protected because you should not need to invoke it directly -- instead use JSON.stringify or toJsonString for stringified JSON. Alternatively, if actual JSON is desired, you should use toJson.

    Returns JsonValue

  • Serialize the message to a JSON string.

    Parameters

    • Optionaloptions: Partial<JsonWriteStringOptions>

    Returns string

  • Parameters

    • bytes: Uint8Array
    • Optionaloptions: Partial<BinaryReadOptions>

    Returns DataRequest

  • Parameters

    • jsonString: string
    • Optionaloptions: Partial<JsonReadOptions>

    Returns DataRequest
