pack-priv final Class ConfinedSession

extends MemorySessionImpl
Class Inheritance
Imports
jdk.internal.invoke.MhUtil, jdk.internal.vm.annotation.ForceInline, java.lang.invoke.MethodHandles, .VarHandle
A confined session, which features an owner thread. The liveness check features an additional confinement check - that is, calling any operation on this session from a thread other than the owner thread will result in an exception. Because of this restriction, checking the liveness bit can be performed in plain mode.
