LocalTxInvocationContext

public LocalTxInvocationContext()
Method Detail

getRunningTransaction

public Transaction getRunningTransaction()
Description copied from interface: TxInvocationContext
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.


isOriginLocal

public boolean isOriginLocal()
Description copied from interface: InvocationContext
Returns true if the call was originated locally, false if it is the result of a remote rpc.


isInTxScope

public boolean isInTxScope()
Description copied from interface: InvocationContext
Returns true if this call is performed in the context of an transaction, false otherwise.


getLockOwner

public Object getLockOwner()
Description copied from interface: InvocationContext
Returns the in behalf of which locks will be aquired.


getGlobalTransaction

public GlobalTransaction getGlobalTransaction()
Description copied from interface: TxInvocationContext
Returns the id of the transaction assoctiated with the current call.


getModifications

public List<WriteCommand> getModifications()
Description copied from interface: TxInvocationContext
Returns all the modifications performed in the scope of the current transaction.


setXaCache

public void setXaCache(TransactionXaAdapter xaAdapter)

lookupEntry

public CacheEntry lookupEntry(Object key)
Description copied from interface: EntryLookup
Retrieves an entry from the collection of looked up entries in the current scope.

Parameters:
key - key to look up
Returns:
an entry, or null if it cannot be found.

getLookedUpEntries

public BidirectionalMap<Object,CacheEntry> getLookedUpEntries()
Description copied from interface: EntryLookup
Retrieves a map of entries looked up within the current scope.

Returns:
a map of looked up entries.

putLookedUpEntry

public void putLookedUpEntry(Object key,
                             CacheEntry e)
Description copied from interface: EntryLookup
Puts an entry in the registry of looked up entries in the current scope.

Parameters:
key - key to store
e - entry to store

putLookedUpEntries

public void putLookedUpEntries(Map<Object,CacheEntry> lookedUpEntries)

removeLookedUpEntry

public void removeLookedUpEntry(Object key)

clearLookedUpEntries

public void clearLookedUpEntries()
Description copied from interface: EntryLookup
Clears the collection of entries looked up


hasLockedKey

public boolean hasLockedKey(Object key)
Description copied from interface: EntryLookup
Using this method should always ensure locks checked in the appropriate scope.

Specified by:
hasLockedKey in interface EntryLookup
Overrides:
hasLockedKey in class AbstractInvocationContext
Parameters:
key - lock to test
Returns:
true if the lock being tested is already held in the current scope, false otherwise.
