Method Detail

getLockEntryCount

public static int getLockEntryCount(java.lang.Object k)

Returns the depth of the lock on the given object.

---

monitorenter

public static void monitorenter(java.lang.Object k)

Monitorenter runtime routine. Checks for thin lock usage, otherwise falls back to inflated locks.

---

monitorexit

public static void monitorexit(java.lang.Object k)

Monitorexit runtime routine. Checks for thin lock usage, otherwise falls back to inflated locks.

---

getMonitor

public static Monitor getMonitor(int lockword)

Get the Monitor object associated with this lockword.

---

allocateInflatedLock

public static Monitor allocateInflatedLock()

---

free

public void free()

---

installInflatedLock

public static void installInflatedLock(java.lang.Object k,
                                       Monitor m)

Installs an inflated lock on the given object. Uses a spin-loop to wait until the object is unlocked or inflated.

---

lock

public void lock(Scheduler.jq_Thread t)

Lock this monitor with the given thread block.

---

unlock

public void unlock(Scheduler.jq_Thread t)

Unlock this monitor with the given thread block.

---

waitOnSemaphore

public void waitOnSemaphore()
