TxnManagerTransaction is a class which captures the internal representation of a transaction in the TxnManagerImpl server. This class is associated with a transaction id. The information encapsulated includes the list of participants which have joined the transaction, the state of the transaction, the crash. The user of a ParticipantHolder must make the association between an instance of a ParticipantHolder and some sort of key or index.

getState

public int getState()

This method returns the state of the transaction. Since the purpose of the set of ParticipantHolders is to associate a Transaction with a group of participants joined the transaction, we would like to get the state of the transaction associated with the aforementioned set.
