        Retrieves the latest workflow template.

        Can retrieve previously instantiated template by specifying optional
        version parameter.

        Example:
            >>> from google.cloud import dataproc_v1
            >>>
            >>> client = dataproc_v1.WorkflowTemplateServiceClient()

            >>>
            >>> response = client.get_workflow_template(name)

        Args:
            name (str): Required. The resource name of the workflow template, as described in
                https://cloud.google.com/apis/design/resource\_names.

                -  For ``projects.regions.workflowTemplates.get``, the resource name of
                   the template has the following format:
                   ``projects/{project_id}/regions/{region}/workflowTemplates/{template_id}``

                -  For ``projects.locations.workflowTemplates.get``, the resource name
                   of the template has the following format:
                   ``projects/{project_id}/locations/{location}/workflowTemplates/{template_id}``
            version (int): Optional. The version of workflow template to retrieve. Only previously
                instantiated versions can be retrieved.

                If unspecified, retrieves the current version.
            retry (Optional[google.api_core.retry.Retry]):  A retry object used
                to retry requests. If ``None`` is specified, requests will
                be retried using a default configuration.
            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.dataproc_v1.types.WorkflowTemplate` 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.
