/**
* 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}.
