getNumberOfInflightTransactions

public int getNumberOfInflightTransactions()

This method works out the number of in-flight transactions currently in the system.

Note: The definition of in-flight (a.k.a. active) transactions can be found in the OMG OTS specification: "[Active is defined as] the state of a transaction when processing is in progress and completion of the transaction has not yet commenced." In addition to the OMG OTS definition, transactions that are marked as abort-only are not considered active. In Arjuna, these considerations are distilled into the following: in-flight transactions are those BasicActions with status() equal to ActionStatus.RUNNING.

Returns:

the number of in-flight transactions currently in the system
