Permissions.implies介绍

[英]Checks to see if this object's PermissionCollection for permissions of the specified permission's type implies the permissions expressed in the permission object. Returns true if the combination of permissions in the appropriate PermissionCollection (e.g., a FilePermissionCollection for a FilePermission) together imply the specified permission.

For example, suppose there is a FilePermissionCollection in this Permissions object, and it contains one FilePermission that specifies "read" access for all files in all subdirectories of the "/tmp" directory, and another FilePermission that specifies "write" access for all files in the "/tmp/scratch/foo" directory. Then if the implies method is called with a permission specifying both "read" and "write" access to files in the "/tmp/scratch/foo" directory, true is returned.

Additionally, if this PermissionCollection contains the AllPermission, this method will always return true.
[中]检查此对象指定权限类型的权限的PermissionCollection是否表示权限对象中表达的权限。如果相应PermissionCollection中的权限组合（例如，FilePermissionCollection中的FilePermission）一起暗示指定的权限，则返回true。
例如，假设此权限对象中有一个FilePermissionCollection，其中一个FilePermission指定“/tmp”目录所有子目录中所有文件的“读取”访问权限，另一个FilePermission指定“/tmp/scratch/foo”目录中所有文件的“写入”访问权限。然后，如果使用指定对“/tmp/scratch/foo”目录中文件的“读取”和“写入”访问权限的权限调用implies方法，则返回true。
此外，如果此PermissionCollection包含AllPermission，则此方法将始终返回true。
