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
typecomponent determines if the entry grants or denies access.The
principalcomponent, sometimes called the "who" component, is aUserPrincipalcorresponding to the identity that the entry grants or denies accessThe
permissionscomponent is a set ofpermissionsThe
flagscomponent is a set offlagsto 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.

newBuilder
Constructs a new builder. The initial value of the type and who components isnull. The initial value of the permissions and flags components is the empty set.- Returns:
- a new builder
-

entry- an ACL entry- Returns:
- a new builder

principal

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
AclEntrythen 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.equalsmethod. -
hashCode
public int hashCode()Returns the hash-code value for this ACL entry.This method satisfies the general contract of the
Object.hashCode()method. -
