public class TransactionTable

extends java.lang.Object

Maintains the mapping between local (Transaction) and global transactions (GlobalTransaction). Also keys modifications and undo-operations) under a given TX

tx_map

protected ConcurrentReaderHashMap tx_map

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

txs

protected java.util.HashMap txs

HashMap, mappings between GlobalTransactions and modifications

get

public GlobalTransaction (src)  get(Transaction (src)  tx)

getLocalTransaction

public Transaction (src)  getLocalTransaction(GlobalTransaction (src)  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
