Method Details

hasModifications

boolean hasModifications()

Checks if there are modifications performed within the tx's scope. Any modifications having Flag.CACHE_MODE_LOCAL are ignored.

getAffectedKeys

Set<Object> getAffectedKeys()

Returns the set of keys that are affected by this transaction. Used to generate appropriate recipient groups for cluster-wide prepare and commit calls.

getGlobalTransaction

GlobalTransaction getGlobalTransaction()

Returns the id of the transaction associated with the current call.

getModifications

List<org.infinispan.commands.write.WriteCommand> getModifications()

Returns the modifications performed in the scope of the current transaction. Any modifications having Flag.CACHE_MODE_LOCAL are ignored. The returned list can be null.

getTransaction

javax.transaction.Transaction getTransaction()

Returns the tx associated with the current thread. This method MUST be guarded with a call to InvocationContext.isOriginLocal(), as Transaction are not propagated from the node where tx was started.

Throws:

IllegalStateException - if the call is performed from a InvocationContext.isOriginLocal()==false context.

addAllAffectedKeys

void addAllAffectedKeys(Collection<?> keys)

Registers a new participant with the transaction.

addAffectedKey

void addAffectedKey(Object key)

isTransactionValid

boolean isTransactionValid()

Returns:

true if the current transaction is in a valid state to perform operations on (i.e.,RUNNING or PREPARING) or false otherwise.

isImplicitTransaction

boolean isImplicitTransaction()

getCacheTransaction

T getCacheTransaction()
