public final class AclEntry extends Object
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 a UserPrincipal
corresponding to the identity
that the entry grants or denies access
The permissions
component is a set of
permissions
The flags
component is a set of flags
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.

Compares the specified object with this ACL entry for equality.

Returns a copy of the flags component.

hashCode()
Returns the hash-code value for this ACL entry.
|
static AclEntry.Builder |
newBuilder()
Constructs a new builder.
|
static AclEntry.Builder |
newBuilder(AclEntry entry)
Constructs a new builder with the components of an existing ACL entry.
|
Set<AclEntryPermission> |
permissions()
Returns a copy of the permissions component.
|
UserPrincipal |

public Set<AclEntryPermission> permissions()
The returned set is a modifiable copy of the permissions.
public Set<AclEntryFlag> flags()
The returned set is a modifiable copy of the flags.
public boolean equals(Object ob)
If the given object is not an AclEntry
then this method
immediately returns false
.
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.
