Method Detail

hasModifications

public boolean hasModifications()

Description copied from interface: TxInvocationContext

Were there any modifications performed within the tx's scope?

Specified by:

hasModifications in interface TxInvocationContext

getAffectedKeys

public Set<Object> getAffectedKeys()

Description copied from interface: TxInvocationContext

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

Specified by:

getAffectedKeys in interface TxInvocationContext

isValidRunningTx

public boolean isValidRunningTx()

Description copied from interface: TxInvocationContext

Returns true if the current tx is either ACTIVE or PREPARING, false otherwise.

Specified by:

isValidRunningTx in interface TxInvocationContext

addAffectedKeys

public void addAffectedKeys(Object... keys)

Description copied from interface: TxInvocationContext

Registers a new participant with the transaction.

Specified by:

addAffectedKeys in interface TxInvocationContext

isValid

public static boolean isValid(Transaction tx)

Return s true of tx's status is ACTIVE or PREPARING

Parameters:

tx -

Returns:

true if the tx is active or preparing

isActive

public static boolean isActive(Transaction tx)

Returns true if transaction is ACTIVE, false otherwise

isPreparing

public static boolean isPreparing(Transaction tx)

Returns true if transaction is PREPARING, false otherwise

assertTransactionValid

public static void assertTransactionValid(TxInvocationContext ctx)

Tests whether the caller is in a valid transaction. If not, will throw a CacheException.

clone

public AbstractTxInvocationContext clone()

Specified by:

clone in interface InvocationContext

Overrides:

clone in class AbstractInvocationContext
