Package org.opensearch.secure_sm

Class ThreadPermission

java.lang.Object
java.security.Permission
java.security.BasicPermission
org.opensearch.secure_sm.ThreadPermission
All Implemented Interfaces:
java.io.Serializable, java.security.Guard
public final class ThreadPermission
extends java.security.BasicPermission
Permission to modify threads or thread groups normally not accessible to the current thread.

SecureSM enforces ThreadGroup security: threads with RuntimePermission("modifyThread") or RuntimePermission("modifyThreadGroup") are only allowed to modify their current thread group or an ancestor of that group.

In some cases (e.g. test runners), code needs to manipulate arbitrary threads, so this Permission provides for that: the targets modifyArbitraryThread and modifyArbitraryThreadGroup allow a thread blanket access to any group.
