+<!-- # Generated by synthtool. DO NOT EDIT! !-->
+# Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of
+experience, education, socio-economic status, nationality, personal appearance,
+race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+*   Using welcoming and inclusive language
+*   Being respectful of differing viewpoints and experiences
+*   Gracefully accepting constructive criticism
+*   Focusing on what is best for the community
+*   Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+*   The use of sexualized language or imagery and unwelcome sexual attention or
+    advances
+*   Trolling, insulting/derogatory comments, and personal or political attacks
+*   Public or private harassment
+*   Publishing others' private information, such as a physical or electronic
+    address, without explicit permission
+*   Other conduct which could reasonably be considered inappropriate in a
+    professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, or to ban temporarily or permanently any
+contributor for other behaviors that they deem inappropriate, threatening,
+offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+This Code of Conduct also applies outside the project spaces when the Project
+Steward has a reasonable belief that an individual's behavior may have a
+negative impact on the project or its community.
+
+## Conflict Resolution
+
+We do not believe that all conflict is bad; healthy debate and disagreement
+often yield positive results. However, it is never okay to be disrespectful or
+to engage in behavior that violates the project’s code of conduct.
+
+If you see someone violating the code of conduct, you are encouraged to address
+the behavior directly with those involved. Many issues can be resolved quickly
+and easily, and this gives people more control over the outcome of their
+dispute. If you are unable to resolve the matter for any reason, or if the
+behavior is threatening or harassing, report it. We are dedicated to providing
+an environment where participants feel welcome and safe.
+
+Reports should be directed to *googleapis-stewards@google.com*, the
+Project Steward(s) for *Google Cloud Client Libraries*. It is the Project Steward’s duty to
+receive and address reported violations of the code of conduct. They will then
+work with a committee consisting of representatives from the Open Source
+Programs Office and the Google Open Source Strategy team. If for any reason you
+are uncomfortable reaching out to the Project Steward, please email
+opensource@google.com.
+
+We will investigate every complaint, but you may not receive a direct response.
+We will use our discretion in determining when and how to follow up on reported
+incidents, which may range from not taking action to permanent expulsion from
+the project and project-sponsored spaces. We will notify the accused of the
+report and provide them an opportunity to discuss it before any action is taken.
+The identity of the reporter will be omitted from the details of the report
+supplied to the accused. In potentially harmful situations, such as ongoing
+harassment or threats to anyone's safety, we may take action without notice.
+
+## Attribution
+
+This Code of Conduct is adapted from the Contributor Covenant, version 1.4,
+available at
+https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

+
+## Supported Node.js Versions
+
+Our client libraries follow the [Node.js release schedule](https://nodejs.org/en/about/releases/).
+Libraries are compatible with all current _active_ and _maintenance_ versions of
+Node.js.
+If you are using an end-of-life version of Node.js, we recommend that you update
+as soon as possible to an actively supported LTS version.
+
+Google's client libraries support legacy versions of Node.js runtimes on a
+best-efforts basis with the following warnings:
+
+* Legacy versions are not tested in continuous integration.
+* Some security patches and features cannot be backported.
+* Dependencies cannot be kept up-to-date.
+
+Client libraries targeting some end-of-life versions of Node.js are available, and
+can be installed through npm [dist-tags](https://docs.npmjs.com/cli/dist-tag).
+The dist-tags follow the naming convention `legacy-(version)`.
+For example, `npm install @google-cloud/vision@legacy-8` installs client libraries
+for versions compatible with Node.js 8.
+
+## Versioning
+
+This library follows [Semantic Versioning](http://semver.org/).
+
+
+
+This library is considered to be **stable**. The code surface will not change in backwards-incompatible ways
+unless absolutely necessary (e.g. because of critical security issues) or with
+an extensive deprecation period. Issues and requests against **stable** libraries
+are addressed with the highest priority.
+

It is also recommended to not add any of the Products involved in the batch delete to a new ProductSet while this operation is running because those Products may still end up deleted. It's not possible to undo the PurgeProducts operation. Therefore, it is recommended to keep the csv files used in ImportProductSets (if that was how you originally built the Product Set) before starting PurgeProducts, in case you need to re-import the data after deletion. If the plan is to purge all of the Products from a ProductSet and then re-use the empty ProductSet to re-import new Products into the empty ProductSet, you must wait until the PurgeProducts operation has finished for that ProductSet.

Therefore, it is recommended to keep the csv files used in ImportProductSets (if that was how you originally built the Product Set) before starting PurgeProducts, in case you need to re-import the data after deletion. If the plan is to purge all of the Products from a ProductSet and then re-use the empty ProductSet to re-import new Products into the empty ProductSet, you must wait until the PurgeProducts operation has finished for that ProductSet.

+   *
+   * @method v1p3beta1.ImageAnnotatorClient#objectLocalization
+   * @param {object|string|Buffer} request A representation of the request
+   *     being sent to the Vision API. This is an
+   *     {@link google.cloud.vision.v1.AnnotateImageRequest AnnotateImageRequest}.
+   *     For simple cases, you may also send a string (the URL or filename of
+   *     the image) or a buffer (the image itself).
+   * @param {object} request.image A dictionary-like object representing the
+   *     image. This should have a single key (`source`, `content`).
+   *
+   *     If the key is `source`, the value should be another object containing
+   *     `imageUri` or `filename` as a key and a string as a value.
+   *
+   *     If the key is `content`, the value should be a Buffer.
+   * @param {object} [callOptions] Optional parameters. You can override the
+   *     default settings for this call, e.g, timeout, retries, paginations,
+   *     etc. See {@link https://googleapis.github.io/gax-nodejs/global.html#CallOptions| gax.CallOptions}
+   *     for the details.
+   * @param {function(?Error, ?object)} [callback] The function which will be
+   *     called with the result of the API call.
+   *
+   *     The second parameter to the callback is an object representing
+   *     [BatchAnnotateImagesResponse]{@link BatchAnnotateImagesResponse}.
+   * @returns {Promise} The promise which resolves to an array. The first
+   *     element of the array is an object representing
+   *     [BatchAnnotateImagesResponse]{@link BatchAnnotateImagesResponse}.
+   *     The promise has a method named "cancel" which cancels the ongoing API
+   *     call.

+   * @param {string} [options.credentials.client_email]
+   * @param {string} [options.credentials.private_key]
+   * @param {string} [options.email] - Account email address. Required when

+   *     the remote host.
+   * @param {string} [options.projectId] - The project ID from the Google
+   *     Developer's Console, e.g. 'grape-spaceship-123'. We will also check
+   *     the environment variable GCLOUD_PROJECT for your project ID. If your
