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

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

Deprecated.

Since 10.0, the blocking variants will be removed

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

@Deprecated
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

Deprecated.

Since 10.0, the blocking variants will be removed

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.
