public final class AclEntryImpl

extends Object

implements AclEntry

This class implements the AclEntry interface, which is used to represent one entry in an Access Control List (ACL).

An ACL is a data structure with multiple AclEntry objects. Each AclEntry object contains a set of permissions associated with a particular principal, which represents an entity such as an individual user or a group.

Additionally, each AclEntry is specified as either positive or negative. If positive, the permissions are to be granted to the associated principal. If negative, the permissions are to be denied. Each principal can have at most one positive AclEntry and one negative entry; that is, multiple positive or negative AclEntries are not allowed for any principal.

An AclEntry is by default positive. An entry becomes a negative entry only if the setNegativePermissions() method is called on it.
