Field Detail

tx_map

protected EDU.oswego.cs.dl.util.concurrent.ConcurrentReaderHashMap tx_map

HashMap, mapping between local (javax.transaction.Transaction) and GlobalTransactions. New: a local TX can have a number of GTXs

HashMap, mappings between GlobalTransactions and modifications

Constructor Detail

TransactionTable

public TransactionTable()

Method Detail

getNumLocalTransactions

public int getNumLocalTransactions()

getNumGlobalTransactions

public int getNumGlobalTransactions()

get

public GlobalTransaction get(javax.transaction.Transaction tx)

getLocalTransaction

public javax.transaction.Transaction getLocalTransaction(GlobalTransaction gtx)

Returns the local transaction associated with a GlobalTransaction. Not very efficient as the values have to be iterated over, don't use frequently

Parameters:

gtx - The GlobalTransaction

Returns:

Transaction. The local transaction associated with a given GlobalTransaction). This will be null if no local transaction is associated with a given GTX

put

public void put(javax.transaction.Transaction tx,
                GlobalTransaction gtx)

get

public TransactionEntry get(GlobalTransaction gtx)

put

public void put(GlobalTransaction tx,
                TransactionEntry entry)

remove

public TransactionEntry remove(GlobalTransaction tx)

remove

public GlobalTransaction remove(javax.transaction.Transaction tx)

addModification

public void addModification(GlobalTransaction gtx,
                            org.jgroups.blocks.MethodCall m)

addUndoOperation

public void addUndoOperation(GlobalTransaction gtx,
                             org.jgroups.blocks.MethodCall m)

addNode

public void addNode(GlobalTransaction gtx,
                    Fqn node)

addLock

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

toString
