<h3>Method Details</h3>
<div class="method">
    <code class="details" id="create">create(parent, body, requestId=None, x__xgafv=None)</code>
  <pre>Creates a variable within the given configuration. You cannot create
a variable with a name that is a prefix of an existing variable name, or a
name that has an existing variable name as a prefix.

To learn more about creating a variable, read the
[Setting and Getting
Data](/deployment-manager/runtime-configurator/set-and-get-variables)
documentation.

Args:
  parent: string, The path to the RutimeConfig resource that this variable should belong to.
The configuration must exist beforehand; the path must be in the format:

`projects/[PROJECT_ID]/configs/[CONFIG_NAME]` (required)
  body: object, The request body. (required)
    The object takes the form of:

{ # Describes a single variable within a RuntimeConfig resource.
    # The name denotes the hierarchical variable name. For example,
    # `ports/serving_port` is a valid variable name. The variable value is an
    # opaque string and only leaf variables can have values (that is, variables
    # that do not have any child variables).
  "text": "A String", # The string value of the variable. The length of the value must be less
      # than 4096 bytes. Empty values are also accepted. For example,
      # `text: "my text value"`. The string must be valid UTF-8.
  "updateTime": "A String", # Output only. The time of the last variable update.
      # Timestamp will be UTC timestamp.
  "state": "A String", # Output only. The current state of the variable. The variable state
      # indicates the outcome of the `variables().watch` call and is visible
      # through the `get` and `list` calls.
  "value": "A String", # The binary value of the variable. The length of the value must be less
      # than 4096 bytes. Empty values are also accepted. The value must be
      # base64 encoded, and must comply with IETF RFC4648
      # (https://www.ietf.org/rfc/rfc4648.txt). Only one of `value` or `text`
      # can be set.
  "name": "A String", # The name of the variable resource, in the format:
      # 
      #     projects/[PROJECT_ID]/configs/[CONFIG_NAME]/variables/[VARIABLE_NAME]
      # 
      # The `[PROJECT_ID]` must be a valid project ID, `[CONFIG_NAME]` must be a
      # valid RuntimeConfig resource and `[VARIABLE_NAME]` follows Unix file system
      # file path naming.
      # 
      # The `[VARIABLE_NAME]` can contain ASCII letters, numbers, slashes and
      # dashes. Slashes are used as path element separators and are not part of the
      # `[VARIABLE_NAME]` itself, so `[VARIABLE_NAME]` must contain at least one
      # non-slash character. Multiple slashes are coalesced into single slash
      # character. Each path segment should match
      # [0-9A-Za-z](?:[_.A-Za-z0-9-]{0,62}[_.A-Za-z0-9])? regular expression.
      # The length of a `[VARIABLE_NAME]` must be less than 256 characters.
      # 
      # Once you create a variable, you cannot change the variable name.
}

  requestId: string, An optional but recommended unique `request_id`. If the server
receives two `create()` requests  with the same
`request_id`, then the second request will be ignored and the
first resource created and stored in the backend is returned.
Empty `request_id` fields are ignored.

It is responsibility of the client to ensure uniqueness of the
`request_id` strings.

`request_id` strings are limited to 64 characters.
  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

<div class="method">
    <code class="details" id="delete">delete(name, x__xgafv=None, recursive=None)</code>
  <pre>Deletes a variable or multiple variables.

If you specify a variable name, then that variable is deleted. If you
specify a prefix and `recursive` is true, then all variables with that
prefix are deleted. You must set a `recursive` to true if you delete
variables by prefix.

Args:
  name: string, The name of the variable to delete, in the format:

`projects/[PROJECT_ID]/configs/[CONFIG_NAME]/variables/[VARIABLE_NAME]` (required)
  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format
  recursive: boolean, Set to `true` to recursively delete multiple variables with the same
prefix.

Returns:
  An object of the form:

    { # A generic empty message that you can re-use to avoid defining duplicated
      # empty messages in your APIs. A typical example is to use it as the request
      # or the response type of an API method. For instance:
      #
      #     service Foo {
      #       rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty);
      #     }

<div class="method">
    <code class="details" id="watch">watch(name, body, x__xgafv=None)</code>
  <pre>Watches a specific variable and waits for a change in the variable's value.
When there is a change, this method returns the new value or times out.

If a variable is deleted while being watched, the `variableState` state is
set to `DELETED` and the method returns the last known variable `value`.

If you set the deadline for watching to a larger value than internal
timeout (60 seconds), the current variable value is returned and the
`variableState` will be `VARIABLE_STATE_UNSPECIFIED`.

To learn more about creating a watcher, read the
[Watching a Variable for
Changes](/deployment-manager/runtime-configurator/watching-a-variable)
documentation.

Args:
  name: string, The name of the variable to watch, in the format:

`projects/[PROJECT_ID]/configs/[CONFIG_NAME]` (required)
  body: object, The request body. (required)
    The object takes the form of:

{ # Request for the `WatchVariable()` method.
    "newerThan": "A String", # If specified, checks the current timestamp of the variable and if the
        # current timestamp is newer than `newerThan` timestamp, the method returns
        # immediately.
        # 
        # If not specified or the variable has an older timestamp, the watcher waits
        # for a the value to change before returning.
  }

  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

Returns:
  An object of the form:

    { # Describes a single variable within a RuntimeConfig resource.
      # The name denotes the hierarchical variable name. For example,
      # `ports/serving_port` is a valid variable name. The variable value is an
      # opaque string and only leaf variables can have values (that is, variables
      # that do not have any child variables).
    "text": "A String", # The string value of the variable. The length of the value must be less
        # than 4096 bytes. Empty values are also accepted. For example,
        # `text: "my text value"`. The string must be valid UTF-8.
    "updateTime": "A String", # Output only. The time of the last variable update.
        # Timestamp will be UTC timestamp.
    "state": "A String", # Output only. The current state of the variable. The variable state
        # indicates the outcome of the `variables().watch` call and is visible
        # through the `get` and `list` calls.
    "value": "A String", # The binary value of the variable. The length of the value must be less
        # than 4096 bytes. Empty values are also accepted. The value must be
        # base64 encoded, and must comply with IETF RFC4648
        # (https://www.ietf.org/rfc/rfc4648.txt). Only one of `value` or `text`
        # can be set.
    "name": "A String", # The name of the variable resource, in the format:
        #
        #     projects/[PROJECT_ID]/configs/[CONFIG_NAME]/variables/[VARIABLE_NAME]
        #
        # The `[PROJECT_ID]` must be a valid project ID, `[CONFIG_NAME]` must be a
        # valid RuntimeConfig resource and `[VARIABLE_NAME]` follows Unix file system
        # file path naming.
        #
        # The `[VARIABLE_NAME]` can contain ASCII letters, numbers, slashes and
        # dashes. Slashes are used as path element separators and are not part of the
        # `[VARIABLE_NAME]` itself, so `[VARIABLE_NAME]` must contain at least one
        # non-slash character. Multiple slashes are coalesced into single slash
        # character. Each path segment should match
        # [0-9A-Za-z](?:[_.A-Za-z0-9-]{0,62}[_.A-Za-z0-9])? regular expression.
        # The length of a `[VARIABLE_NAME]` must be less than 256 characters.
        #
        # Once you create a variable, you cannot change the variable name.
