Method Summary

Modifier and Type	Method	Description
long	awaitPendingTransactionsForAllKeys(org.infinispan.context.impl.TxInvocationContext<?> ctx, java.util.Collection<java.lang.Object> keys, long time, java.util.concurrent.TimeUnit unit)	It waits for any transaction with older topology id to complete that may have the lock for any key in keys acquired.
long	awaitPendingTransactionsForKey(org.infinispan.context.impl.TxInvocationContext<?> ctx, java.lang.Object key, long time, java.util.concurrent.TimeUnit unit)	It waits for any transaction with older topology id to complete that may have the lock for key acquired.
PendingLockPromise	checkPendingTransactionsForKey(org.infinispan.context.impl.TxInvocationContext<?> ctx, java.lang.Object key, long time, java.util.concurrent.TimeUnit unit)	Same as awaitPendingTransactionsForKey(TxInvocationContext, Object, long, TimeUnit) but non-blocking.
PendingLockPromise	checkPendingTransactionsForKeys(org.infinispan.context.impl.TxInvocationContext<?> ctx, java.util.Collection<java.lang.Object> keys, long time, java.util.concurrent.TimeUnit unit)	Same as awaitPendingTransactionsForAllKeys(TxInvocationContext, Collection, long, TimeUnit) but non-blocking.

Method Detail

checkPendingTransactionsForKey

PendingLockPromise checkPendingTransactionsForKey(org.infinispan.context.impl.TxInvocationContext<?> ctx,
                                                  java.lang.Object key,
                                                  long time,
                                                  java.util.concurrent.TimeUnit unit)

Same as awaitPendingTransactionsForKey(TxInvocationContext, Object, long, TimeUnit) but non-blocking.

Multiple invocations with the same transaction returns the same PendingLockPromise. For cleanup purposes, awaitPendingTransactionsForKey(TxInvocationContext, Object, long, TimeUnit) must be invoked afterwards.

Parameters:

ctx - the TxInvocationContext.

key - the key to check.

time - timeout.

unit - TimeUnit of time.

Returns:

a PendingLockPromise.

checkPendingTransactionsForKeys

PendingLockPromise checkPendingTransactionsForKeys(org.infinispan.context.impl.TxInvocationContext<?> ctx,
                                                   java.util.Collection<java.lang.Object> keys,
                                                   long time,
                                                   java.util.concurrent.TimeUnit unit)

Same as awaitPendingTransactionsForAllKeys(TxInvocationContext, Collection, long, TimeUnit) but non-blocking.

Multiple invocations with the same transaction returns the same PendingLockPromise. For cleanup purposes, awaitPendingTransactionsForAllKeys(TxInvocationContext, Collection, long, TimeUnit) must be invoked afterwards.

Parameters:

ctx - the TxInvocationContext.

keys - the keys to check.

time - timeout.

unit - TimeUnit of time.

Returns:

a PendingLockPromise.

awaitPendingTransactionsForKey

long awaitPendingTransactionsForKey(org.infinispan.context.impl.TxInvocationContext<?> ctx,
                                    java.lang.Object key,
                                    long time,
                                    java.util.concurrent.TimeUnit unit)
                             throws java.lang.InterruptedException

It waits for any transaction with older topology id to complete that may have the lock for key acquired.

Parameters:

ctx - the TxInvocationContext.

key - the key to check.

time - timeout.

unit - TimeUnit of time.

Returns:

the remaining timeout.

Throws:

java.lang.InterruptedException - if the thread is interrupted while waiting.

awaitPendingTransactionsForAllKeys

long awaitPendingTransactionsForAllKeys(org.infinispan.context.impl.TxInvocationContext<?> ctx,
                                        java.util.Collection<java.lang.Object> keys,
                                        long time,
                                        java.util.concurrent.TimeUnit unit)
                                 throws java.lang.InterruptedException

It waits for any transaction with older topology id to complete that may have the lock for any key in keys acquired.

Parameters:

ctx - the TxInvocationContext.

keys - the keys to check.

time - timeout.

unit - TimeUnit of time.

Returns:

the remaining timeout.

Throws:

java.lang.InterruptedException - if the thread is interrupted while waiting.
