Class AllPermission

java.lang.Object
  java.security.Permission
      java.security.AllPermission

All Implemented Interfaces:

Guard, Serializable

public final class AllPermission

extends Permission

The AllPermission is a permission that implies all other permissions. AllPermission是个包含所有其他许可的许可。

Note: Granting AllPermission should be done with extreme care, as it implies all other permissions. Thus, it grants code the ability to run with security disabled. Extreme caution should be taken before granting such a permission to code. This permission should be used only during testing, or in extremely rare cases where an application or applet is completely trusted and adding the necessary permissions to the policy is prohibitively cumbersome. 注意：授予AllPermission应当极为小心，因为它包含了所有其它许可。因此，它授予运行代码的权力， 而无需安全检查。该许可应当只在测试时使用，或者在极少数的情况下，应用或applet完全被信任， 向策略中添加必要的许可会使代码笨拙。

Parameters:

name - ignored 被忽略

actions - ignored. 被忽略。

implies

public boolean implies(Permission p)

Specified by:

implies in class Permission

Parameters:

p - the permission to check against. 要检查的许可。

Returns:

return

equals

public boolean equals(Object obj)

Checks two AllPermission objects for equality. Two AllPermission objects are always equal. 检查两个AllPermission对象是否相等。两个AllPermission对象总是相等。

Specified by:

equals in class Permission

Parameters:

obj - the object we are testing for equality with this object. 要和当前对象测试相等性的对象。

Returns:

true if obj is an AllPermission, false otherwise. 如果obj是一个AllPermission，返回true，否则为false。

hashCode

public int hashCode()

Returns the hash code value for this object. 返回该对象的哈希码值。

Specified by:

hashCode in class Permission

Returns:

a hash code value for this object. 该对象的哈希码值。

Returns a new PermissionCollection object for storing AllPermission objects. 返回一个PermissionCollection对象，用于存储AllPermission对象。

Overrides:

newPermissionCollection in class Permission

Returns:

a new PermissionCollection object suitable for storing AllPermissions. 一个PermissionCollection对象，适合存储AllPermission对象。
