Method Detail

setBindings

public final Policy.Builder setBindings(Map<Role,Set<Identity>> bindings)

Replaces the builder's map of bindings with the given map of bindings.

Throws:

NullPointerException - if the given map is null or contains any null keys or values

IllegalArgumentException - if any identities in the given map are null

removeRole

public final Policy.Builder removeRole(Role role)

Removes the role (and all identities associated with that role) from the policy.

addIdentity

public final Policy.Builder addIdentity(Role role,
                                        Identity first,
                                        Identity... others)

Adds one or more identities to the policy under the role specified.

Throws:

NullPointerException - if the role or any of the identities is null.

removeIdentity

public final Policy.Builder removeIdentity(Role role,
                                           Identity first,
                                           Identity... others)

Removes one or more identities from an existing binding. Does nothing if the binding associated with the provided role doesn't exist.

setEtag

public final Policy.Builder setEtag(String etag)

Sets the policy's etag.

Etags are used for optimistic concurrency control as a way to help prevent simultaneous updates of a policy from overwriting each other. It is strongly suggested that systems make use of the etag in the read-modify-write cycle to perform policy updates in order to avoid race conditions. An etag is returned in the response to getIamPolicy, and systems are expected to put that etag in the request to setIamPolicy to ensure that their change will be applied to the same version of the policy. If no etag is provided in the call to setIamPolicy, then the existing policy is overwritten blindly.

setVersion

protected final Policy.Builder setVersion(int version)

Sets the version of the policy. The default version is 0, meaning only the "owner", "editor", and "viewer" roles are permitted. If the version is 1, you may also use other roles.

build

public final Policy build()

Creates a Policy object.
