Class AclEntry
The ACL entry represented by this class is based on the ACL model specified in RFC 3530: Network File System (NFS) version 4 Protocol. Each entry has four components as follows:
The
type
component determines if the entry grants or denies access.The
principal
component, sometimes called the "who" component, is aUserPrincipal
corresponding to the identity that the entry grants or denies accessThe
permissions
component is a set ofpermissions
The
flags
component is a set offlags
to indicate how entries are inherited and propagated
ACL entries are created using an associated AclEntry.Builder
object by
invoking its build
method.
ACL entries are immutable and are safe for use by multiple concurrent threads.

. The initial value of the permissions and flags components is the empty set.- Returns:
- a new builder

permissions
Returns a copy of the permissions component.The returned set is a modifiable copy of the permissions.
- Returns:
- the permissions component
-
flags
Returns a copy of the flags component.The returned set is a modifiable copy of the flags.
- Returns:
- the flags component
-
equals
Compares the specified object with this ACL entry for equality.If the given object is not an
AclEntry
then this method immediately returnsfalse
.For two ACL entries to be considered equals requires that they are both the same type, their who components are equal, their permissions components are equal, and their flags components are equal.
This method satisfies the general contract of the
Object.equals
method. -
hashCode
public int hashCode()Returns the hash-code value for this ACL entry.This method satisfies the general contract of the
Object.hashCode()
method. -
