Method Detail

isTransactionValid

public 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.

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.

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 associated 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.

setLocalTransaction

public void setLocalTransaction(LocalTransaction localTransaction)

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 Map<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: InvocationContext

Returns true if the lock being tested is already held in the current scope, false otherwise.

Specified by:

hasLockedKey in interface InvocationContext

Overrides:

hasLockedKey in class AbstractInvocationContext

Parameters:

key - lock to test

remoteLocksAcquired

public void remoteLocksAcquired(Collection<Address> nodes)

getRemoteLocksAcquired

public Collection<Address> getRemoteLocksAcquired()

getCacheTransaction

public AbstractCacheTransaction getCacheTransaction()

Specified by:

getCacheTransaction in interface TxInvocationContext

Specified by:

getCacheTransaction in class AbstractTxInvocationContext

getLockedKeys

public Set<Object> getLockedKeys()

Description copied from interface: InvocationContext

Returns the set of keys that are locked for writing.

addLockedKey

public void addLockedKey(Object key)

Description copied from interface: InvocationContext

Tracks the given key as locked by this invocation context.

getTransaction

public Transaction getTransaction()

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.

Specified by:

getTransaction in interface TxInvocationContext

Overrides:

getTransaction in class AbstractTxInvocationContext
