public interface UserPrincipal
extends Principal

A Principal representing an identity used to determine access rights to objects in a file system.

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.

A UserPrincipal object is an abstract representation of an identity. It has a name that is typically the username or account name that it represents. User principal objects may be returned by FileAttributeView implementations that provide access to identity related attributes. For example, the PosixFileAttributeView provides access to a file's owner.
