Class AclEntry

java.lang.Object
  java.nio.file.attribute.AclEntry

public final class AclEntry
extends Object

Disabled: no SafeJ information.

An entry in an access control list (ACL).

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:

1. The type component determines if the entry grants or denies access.

2. The principal component, sometimes called the "who" component, is a UserPrincipal corresponding to the identity that the entry grants or denies access

3. The permissions component is a set of permissions

4. 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.

Method Detail

newBuilder

public static AclEntry.Builder newBuilder()

Class is disabled.

Constructs a new builder. The initial value of the type and who components is null. The initial value of the permissions and flags components is the empty set.

Returns:

a new builder

newBuilder

public static AclEntry.Builder newBuilder(AclEntry entry)

Class is disabled.

Constructs a new builder with the components of an existing ACL entry.

Parameters:

entry - an ACL entry

Returns:

a new builder

type

public AclEntryType type()

Class is disabled.

Returns the ACL entry type.

principal

public UserPrincipal principal()

Class is disabled.

Returns the principal component.

permissions

public Set<AclEntryPermission> permissions()

Class is disabled.

Returns a copy of the permissions component.

The returned set is a modifiable copy of the permissions.

flags

public Set<AclEntryFlag> flags()

Class is disabled.

Returns a copy of the flags component.

The returned set is a modifiable copy of the flags.

equals

public boolean equals(Object ob)

Class is disabled.

Compares the specified object with this ACL entry for equality.

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.

Overrides:

equals in class Object

Parameters:

ob - the object to which this object is to be compared

Returns:

true if, and only if, the given object is an AclEntry that is identical to this AclEntry

Object.hashCode(), HashMap

hashCode

public int hashCode()

Class is disabled.

Returns the hash-code value for this ACL entry.

This method satisfies the general contract of the Object.hashCode() method.

Overrides:

hashCode in class Object

Returns:

a hash code value for this object.

See Also:

Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

toString

public String toString()

Class is disabled.

Returns the string representation of this ACL entry.

Overrides:

toString in class Object

Returns:

the string representation of this entry
