| /** | |
| * A {@code Principal} representing an identity used to determine access rights | |
| * to objects in a file system. | |
| * | |
| * <p> On many platforms and file systems an entity requires appropriate access | |
| * rights or permissions in order to access objects in a file system. The | |
| * access rights are generally performed by checking the identity of the entity. | |
| * For example, on implementations that use Access Control Lists (ACLs) to | |
| * enforce privilege separation then a file in the file system may have an | |
| * associated ACL that determines the access rights of identities specified in | |
| * the ACL. | |
| * | |
| * <p> A {@code UserPrincipal} object is an abstract representation of an | |
| * identity. It has a {@link #getName() name} that is typically the username or | |
| * account name that it represents. User principal objects may be obtained using | |
| * a {@link UserPrincipalLookupService}, or returned by {@link | |
| * FileAttributeView} implementations that provide access to identity related | |
| * attributes. For example, the {@link AclFileAttributeView} and {@link | |
| * PosixFileAttributeView} provide access to a file's {@link | |
| * PosixFileAttributes#owner owner}. | |
