Examples of java.security.Permissions.implies()

java.security.Permissions.implies()
Checks to see if this object's PermissionCollection for permissions of the specified permission's class 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.
@param permission the Permission object to check. @return true if "permission" is implied by the permissions in thePermissionCollection it belongs to, false if not.
