<P>
This is the interface used for representing one entry in an Access
Control List (ACL).
该接口用来表示访问控制列表中（ACL）的一个入口。<p>

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
<A HREF="../../../java/security/acl/AclEntry.html#setNegativePermissions()"><CODE>setNegativePermissions</CODE></A>
method is called on it.
ACL可以认为是包含多个ACL入口对象的数据结构，每个ACL入口包含特定主体相关的一组许可
（主体表示一个实体，比如个体或组）。另为，每个ACL入口都可以用肯定或否定描述：肯定表示许可被授予相关联的主体，否定
表示拒绝的许可。每个主体最多有一个肯定ACL入口和一个否定入口，也就是说，任何主体都不允许有多个肯定或否定ACL入口。
注：ACL入口默认为肯定，只有调用setNegativePermissions方法入口才会成为否定入口。
