Interface Permission

public interface Permission

The basic interface to queries on security and privacy of a Node.

The static values represent the right to access the various restricted interfaces of a Node.

The READ permission represents access to the Content of a Node. Without this, a User may only access a Node's NID and Type.

The EDIT permission represents access to an Editor for a Node. Without this permission, a User may not modify the contents of a Node. When the owner of a Node removes his/her own EDIT permission, then the Node is read-only. An EDIT permission cannot be granted to anyone without READ permission.

The HISTORY permission allows a User access to the NodeHistory for a Node. This allows one to examine the audit trail or provenance of a Node.

The DELEGATE permission allows a User to delegate a subset of his own permissions to another User or revoke permissions previously delegated. If this permission is revoked, then all such delegated permissions are automatically revoked.

The MANAGE permission allows a User access to the NodeManager interface. This enables a rather complete manipulation of a Node's permissions.

On creation, the owner of a Node is granted all of these permissions.
