Examples of java.nio.file.attribute.UserPrincipal

java.nio.file.attribute.UserPrincipal
A {@code Principal} representing an identity used to determine access rightsto 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 {@code UserPrincipal} object is an abstract representation of anidentity. It has a {@link #getName() name} that is typically the username oraccount 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 relatedattributes. For example, the {@link AclFileAttributeView} and {@link PosixFileAttributeView} provide access to a file's {@link PosixFileAttributes#owner owner}. @since 1.7
