AclEntry

public final class AclEntry
extends Object

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

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:

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 Builder object by invoking its build method.

ACL entries are immutable and are safe for use by multiple concurrent threads.

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Public methods

equals

Added in API level 26

public boolean equals (Object ob)

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.

Parameters
`ob`	`Object`: the object to which this object is to be compared

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

flags

Added in API level 26

public Set<AclEntryFlag> flags ()

Returns a copy of the flags component.

The returned set is a modifiable copy of the flags.

Returns
`Set<AclEntryFlag>`	the flags component

hashCode

Added in API level 26

public int hashCode ()

Returns the hash-code value for this ACL entry.

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

Returns
`int`	a hash code value for this object.

newBuilder

Added in API level 26

public static AclEntry.Builder newBuilder (AclEntry entry)

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

Parameters
`entry`	`AclEntry`: an ACL entry

Returns
`AclEntry.Builder`	a new builder

newBuilder

Added in API level 26

public static AclEntry.Builder newBuilder ()

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
`AclEntry.Builder`	a new builder

permissions

Added in API level 26

public Set<AclEntryPermission> permissions ()

Returns a copy of the permissions component.

The returned set is a modifiable copy of the permissions.

Returns
`Set<AclEntryPermission>`	the permissions component

principal

Added in API level 26

public UserPrincipal principal ()

Returns the principal component.

Returns
`UserPrincipal`	the principal component

toString

Added in API level 26

public String toString ()

Returns the string representation of this ACL entry.

Returns
`String`	the string representation of this entry

type

Added in API level 26

public AclEntryType type ()

Returns the ACL entry type.

Returns
`AclEntryType`	the ACL entry type
