atomicGet

public final long atomicGet()

Description copied from interface: TxnLong

Atomically gets the value. The value could be stale as soon as it is returned. This method doesn't care about any running txns. It could be that this call fails e.g. when a ref is locked. If you don't care about correct orderings, see the TxnLong.atomicWeakGet().

Specified by:

atomicGet in interface TxnLong

Returns:

the current value.

atomicWeakGet

public final long atomicWeakGet()

Description copied from interface: TxnLong

Atomically gets the value without providing any ordering guarantees. This method is extremely cheap and will never fail. So even if the ref is privatized, this call will still complete.

It is the best method to call if you just want to get the current value stored.

Specified by:

atomicWeakGet in interface TxnLong

Returns:

the value.

public final long atomicSet(long newValue)

Description copied from interface: TxnLong

Atomically sets the value and returns the new value. This method doesn't care about any running txns.

public final long atomicGetAndSet(long newValue)

Description copied from interface: TxnLong

Atomically sets the value and returns the previous value. This method doesn't care about any running txns.

atomicGetAndSet in interface TxnLong

Parameters:

newValue - the new value.

Returns:

the old value.

commute

public final void commute(LongFunction function)

Description copied from interface: TxnLong

Applies the function on the ref in a commuting manner. So if there are no dependencies, the function will commute. If somehow there already is a dependency or a dependency is formed on the result of the commuting function, the function will not commute and will be exactly the same as an alter.

This is different than the behavior in Clojure where the commute will be re-applied at the end of the txn, even though some dependency is introduced, which can lead to inconsistencies.

This call lifts on the Txn stored in the TxnThreadLocal.

Specified by:

commute in interface TxnLong

Parameters:

function - the function to apply to this reference.

commute

public final void commute(Txn tx,
 LongFunction function)

Description copied from interface: TxnLong

This is different than the behavior in Clojure where the commute will be re-applied at the end of the txn, even though some dependency is introduced, which can lead to inconsistencies.

This call lifts on the Txn stored in the TxnThreadLocal.

Specified by:
