Detects the language of text within a request.
Example:
>>> from google.cloud import translate_v3beta1
>>>
>>> client = translate_v3beta1.TranslationServiceClient()
>>>
>>> response = client.detect_language()
Args:
parent (str): Required. Location to make a regional or global call.
Format: ``projects/{project-id}/locations/{location-id}``.
For global calls, use ``projects/{project-id}/locations/global``.
Only models within the same region (has same location-id) can be used.
Otherwise an INVALID\_ARGUMENT (400) error is returned.
model (str): Optional. The language detection model to be used.
Format:
``projects/{project-id}/locations/{location-id}/models/language-detection/{model-id}``
Only one language detection model is currently supported:
``projects/{project-id}/locations/{location-id}/models/language-detection/default``.
If not specified, the default model is used.
content (str): The content of the input stored as a string.
mime_type (str): Optional. The format of the source text, for example, "text/html",
"text/plain". If left blank, the MIME type defaults to "text/html".
retry (Optional[google.api_core.retry.Retry]): A retry object used
to retry requests. If ``None`` is specified, requests will not
be retried.
timeout (Optional[float]): The amount of time, in seconds, to wait
for the request to complete. Note that if ``retry`` is
specified, the timeout applies to each individual attempt.
metadata (Optional[Sequence[Tuple[str, str]]]): Additional metadata
that is provided to the method.
Returns:
A :class:`~google.cloud.translate_v3beta1.types.DetectLanguageResponse` instance.
Raises:
google.api_core.exceptions.GoogleAPICallError: If the request
failed for any reason.
google.api_core.exceptions.RetryError: If the request failed due
to a retryable error and retry attempts failed.
ValueError: If the parameters are invalid.
