defmodule GoogleApi.CloudResourceManager.V1.Model.ListPolicy do
  @moduledoc """
  Used in `policy_type` to specify how `list_policy` behaves at this resource. `ListPolicy` can define specific values and subtrees of Cloud Resource Manager resource hierarchy (`Organizations`, `Folders`, `Projects`) that are allowed or denied by setting the `allowed_values` and `denied_values` fields. This is achieved by using the `under:` and optional `is:` prefixes. The `under:` prefix is used to denote resource subtree values. The `is:` prefix is used to denote specific values, and is required only if the value contains a ":". Values prefixed with "is:" are treated the same as values with no prefix. Ancestry subtrees must be in one of the following formats: - "projects/", e.g. "projects/tokyo-rain-123" - "folders/", e.g. "folders/1234" - "organizations/", e.g. "organizations/1234" The `supports_under` field of the associated `Constraint` defines whether ancestry prefixes can be used. You can set `allowed_values` and `denied_values` in the same `Policy` if `all_values` is `ALL_VALUES_UNSPECIFIED`. `ALLOW` or `DENY` are used to allow or deny all values. If `all_values` is set to either `ALLOW` or `DENY`, `allowed_values` and `denied_values` must be unset.

  ## Attributes

  *   `allValues` (*type:* `String.t`, *default:* `nil`) - The policy all_values state.
  *   `allowedValues` (*type:* `list(String.t)`, *default:* `nil`) - List of values allowed at this resource. Can only be set if `all_values` is set to `ALL_VALUES_UNSPECIFIED`.
  *   `deniedValues` (*type:* `list(String.t)`, *default:* `nil`) - List of values denied at this resource. Can only be set if `all_values` is set to `ALL_VALUES_UNSPECIFIED`.
  *   `inheritFromParent` (*type:* `boolean()`, *default:* `nil`) - Determines the inheritance behavior for this `Policy`. By default, a `ListPolicy` set at a resource supersedes any `Policy` set anywhere up the resource hierarchy. However, if `inherit_from_parent` is set to `true`, then the values from the effective `Policy` of the parent resource are inherited, meaning the values set in this `Policy` are added to the values inherited up the hierarchy. Setting `Policy` hierarchies that inherit both allowed values and denied values isn't recommended in most circumstances to keep the configuration simple and understandable. However, it is possible to set a `Policy` with `allowed_values` set that inherits a `Policy` with `denied_values` set. In this case, the values that are allowed must be in `allowed_values` and not present in `denied_values`. For example, suppose you have a `Constraint` `constraints/serviceuser.services`, which has a `constraint_type` of `list_constraint`, and with `constraint_default` set to `ALLOW`. Suppose that at the Organization level, a `Policy` is applied that restricts the allowed API activations to {`E1`, `E2`}. Then, if a `Policy` is applied to a project below the Organization that has `inherit_from_parent` set to `false` and field all_values set to DENY, then an attempt to activate any API will be denied. The following examples demonstrate different possible layerings for `projects/bar` parented by `organizations/foo`: Example 1 (no inherited values): `organizations/foo` has a `Policy` with values: {allowed_values: "E1" allowed_values:"E2"} `projects/bar` has `inherit_from_parent` `false` and values: {allowed_values: "E3" allowed_values: "E4"} The accepted values at `organizations/foo` are `E1`, `E2`. The accepted values at `projects/bar` are `E3`, and `E4`. Example 2 (inherited values): `organizations/foo` has a `Policy` with values: {allowed_values: "E1" allowed_values:"E2"} `projects/bar` has a `Policy` with values: {value: "E3" value: "E4" inherit_from_parent: true} The accepted values at `organizations/foo` are `E1`, `E2`. The accepted values at `projects/bar` are `E1`, `E2`, `E3`, and `E4`. Example 3 (inheriting both allowed and denied values): `organizations/foo` has a `Policy` with values: {allowed_values: "E1" allowed_values: "E2"} `projects/bar` has a `Policy` with: {denied_values: "E1"} The accepted values at `organizations/foo` are `E1`, `E2`. The value accepted at `projects/bar` is `E2`. Example 4 (RestoreDefault): `organizations/foo` has a `Policy` with values: {allowed_values: "E1" allowed_values:"E2"} `projects/bar` has a `Policy` with values: {RestoreDefault: {}} The accepted values at `organizations/foo` are `E1`, `E2`. The accepted values at `projects/bar` are either all or none depending on the value of `constraint_default` (if `ALLOW`, all; if `DENY`, none). Example 5 (no policy inherits parent policy): `organizations/foo` has no `Policy` set. `projects/bar` has no `Policy` set. The accepted values at both levels are either all or none depending on the value of `constraint_default` (if `ALLOW`, all; if `DENY`, none). Example 6 (ListConstraint allowing all): `organizations/foo` has a `Policy` with values: {allowed_values: "E1" allowed_values: "E2"} `projects/bar` has a `Policy` with: {all: ALLOW} The accepted values at `organizations/foo` are `E1`, E2`. Any value is accepted at `projects/bar`. Example 7 (ListConstraint allowing none): `organizations/foo` has a `Policy` with values: {allowed_values: "E1" allowed_values: "E2"} `projects/bar` has a `Policy` with: {all: DENY} The accepted values at `organizations/foo` are `E1`, E2`. No value is accepted at `projects/bar`. Example 10 (allowed and denied subtrees of Resource Manager hierarchy): Given the following resource hierarchy O1->{F1, F2}; F1->{P1}; F2->{P2, P3}, `organizations/foo` has a `Policy` with values: {allowed_values: "under:organizations/O1"} `projects/bar` has a `Policy` with: {allowed_values: "under:projects/P3"} {denied_values: "under:folders/F2"} The accepted values at `organizations/foo` are `organizations/O1`, `folders/F1`, `folders/F2`, `projects/P1`, `projects/P2`, `projects/P3`. The accepted values at `projects/bar` are `organizations/O1`, `folders/F1`, `projects/P1`.
  *   `suggestedValue` (*type:* `String.t`, *default:* `nil`) - Optional. The Google Cloud Console will try to default to a configuration that matches the value specified in this `Policy`. If `suggested_value` is not set, it will inherit the value specified higher in the hierarchy, unless `inherit_from_parent` is `false`.
