Enum Constant Details

USER

public static final AclEntryType USER

An ACL entry applied to a specific user. These ACL entries can be unnamed, which applies to the file owner, or named, which applies to the specific named user.

GROUP

public static final AclEntryType GROUP

An ACL entry applied to a specific group. These ACL entries can be unnamed, which applies to the file's group, or named, which applies to the specific named group.

MASK

public static final AclEntryType MASK

An ACL mask entry. Mask entries are unnamed. During permission checks, the mask entry interacts with all ACL entries that are members of the group class. This consists of all named user entries, the unnamed group entry, and all named group entries. For each such entry, any permissions that are absent from the mask entry are removed from the effective permissions used during the permission check.

OTHER

public static final AclEntryType OTHER

An ACL entry that applies to all other users that were not covered by one of the more specific ACL entry types.

Method Details

values

public static AclEntryType[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static AclEntryType valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

toString

@Unstable
public String toString()

Overrides:

toString in class Enum<AclEntryType>

toStringStable
