Field Detail

tx_map

protected HashMap tx_map

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

---

txs

protected HashMap txs

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(Transaction tx)

---

getLocalTransactions

public List getLocalTransactions(GlobalTransaction gtx)

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

Parameters:

gtx - The GlobalTransaction

Returns:

List. A list of local transactions (there may be more than 1 local TX associated with a given GlobalTransaction). This will be null if no local transactions are associated with a given GTX
