Any unset fields are ignored.

A `DevicePolicy` specifies requirements for requests from devices to be granted access levels, it does not do any enforcement on the device. `DevicePolicy` acts as an AND over all specified fields, and each repeated field is an OR over its elements. Any unset fields are ignored. For example, if the proto is { os_type : DESKTOP_WINDOWS, os_type : DESKTOP_LINUX, encryption_status: ENCRYPTED}, then the DevicePolicy will be true for requests originating from encrypted Linux desktops and encrypted Windows desktops. # Device specific restrictions, all restrictions must hold for the Condition to be true. If not specified, all devices are allowed.
                &quot;requireScreenlock&quot;: True or False, # Whether or not screenlock is required for the DevicePolicy to be true. Defaults to `false`.

    &quot;metadata&quot;: { # Service-specific metadata associated with the operation. It typically contains progress information and common metadata such as create time. Some services might not provide such metadata. Any method that returns a long-running operation should document the metadata type, if any.

If the original method is standard `Get`/`Create`/`Update`, the response should be the resource. For other methods, the response should have the type `XxxResponse`, where `Xxx` is the original method name. For example, if the original method name is `TakeSnapshot()`, the inferred response type is `TakeSnapshotResponse`.
