                are specified, the client will attempt to ascertain the

                automatically.

                Custom options for the client.

                1. The ``api_endpoint`` property can be used to override the
                default endpoint provided by the client when ``transport`` is
                not explicitly provided. Only if this property is not set and
                ``transport`` was not explicitly provided, the endpoint is
                determined by the GOOGLE_API_USE_MTLS_ENDPOINT environment
                variable, which have one of the following values:
                "always" (always use the default mTLS endpoint), "never" (always
                use the default regular endpoint) and "auto" (auto-switch to the
                default mTLS endpoint if client certificate is present; this is
                the default value).

                2. If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable
                is "true", then the ``client_cert_source`` property can be used
                to provide a client certificate for mTLS transport. If
                not provided, the default SSL client certificate will be used if
                present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not
                set, no client certificate will be used.

                3. The ``universe_domain`` property can be used to override the
                default "googleapis.com" universe. Note that the ``api_endpoint``
                property still takes precedence; and ``universe_domain`` is

            parent (str):
                Required. Project or location to make a call. Must refer
                to a caller's project.

                Format: ``projects/{project-number-or-id}`` or

                ``projects/{project-number-or-id}``.

                Non-global location is required for requests using
                AutoML models or custom glossaries.

                Models and glossaries must be within the same region
                (have same location-id), otherwise an INVALID_ARGUMENT
                (400) error is returned.

                This corresponds to the ``parent`` field

            target_language_code (str):

                text, set to one of the language codes
                listed in Language Support.

                should not be set.
            contents (MutableSequence[str]):
                Required. The content of the input in
                string format. We recommend the total
                content be less than 30,000 codepoints.
                The max length of this field is 1024.
                Use BatchTranslateText for larger text.

                should not be set.
            model (str):
                Optional. The ``model`` type requested for this
                translation.

                The format depends on model type:

                -  AutoML Translation models:
                   ``projects/{project-number-or-id}/locations/{location-id}/models/{model-id}``

                -  General (built-in) models:
                   ``projects/{project-number-or-id}/locations/{location-id}/models/general/nmt``,

                For global (non-regionalized) requests, use
                ``location-id`` ``global``. For example,
                ``projects/{project-number-or-id}/locations/global/models/general/nmt``.

                If not provided, the default Google model (NMT) will be
                used

                This corresponds to the ``model`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            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".

                This corresponds to the ``mime_type`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            source_language_code (str):
                Optional. The ISO-639 language code
                of the input text if known, for example,
                "en-US" or "sr-Latn". Supported language
                codes are listed in Language Support. If
                the source language isn't specified, the
                API attempts to identify the source
                language automatically and returns the
                source language within the response.

                This corresponds to the ``source_language_code`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            retry (google.api_core.retry.Retry): Designation of what errors, if any,
                should be retried.
            timeout (float): The timeout for this request.
            metadata (Sequence[Tuple[str, str]]): Strings which should be
                sent along with the request as metadata.

                The request object. The request for listing Adaptive MT
                sentences from a Dataset/File.
            parent (str):
                Required. The resource name of the project from which to
                list the Adaptive MT files. The following format lists
                all sentences under a file.
                ``projects/{project}/locations/{location}/adaptiveMtDatasets/{dataset}/adaptiveMtFiles/{file}``
                The following format lists all sentences within a
                dataset.
                ``projects/{project}/locations/{location}/adaptiveMtDatasets/{dataset}``

                This corresponds to the ``parent`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            retry (google.api_core.retry.Retry): Designation of what errors, if any,
                should be retried.
            timeout (float): The timeout for this request.
            metadata (Sequence[Tuple[str, str]]): Strings which should be
                sent along with the request as metadata.

        Returns:
            google.cloud.translate_v3.services.translation_service.pagers.ListAdaptiveMtSentencesPager:
                List AdaptiveMt sentences response.
