This interface was deprecated
in API level 33.
This class is deprecated and subject to removal in a future
version of Java SE. It has been replaced by java.security.Policy
and related classes since 1.2.
This is the interface used for representing one entry in an Access Control List (ACL).
An ACL can be thought of as a data structure with multiple ACL entry
objects. Each ACL entry object contains a set of permissions associated
with a particular principal. (A principal represents an entity such as
an individual user or a group). Additionally, each ACL entry is specified
as being 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 ACL entry
and one negative entry; that is, multiple positive or negative ACL
entries are not allowed for any principal.
Note: ACL entries are by default positive. An entry becomes a
negative entry only if the
setNegativePermissions
method is called on it.
