ArmTransaction

For most applications, ArmTransaction is the most important of all the ARM classes, and the most frequently used. Instances of ArmTransaction represent transactions when they execute. A "transaction" is any unit of work that has a clearly understood beginning and ending point, and which begins and ends in the same VM. ArmTransaction is created with the newArmTransaction() method of ArmTransactionFactory.

		ArmConstants.STATUS_ABORT - if the transaction was blocked on a thread.
      ArmConstants.STATUS_FAILED - If the transaction failed.
      ArmConstants.STATUS_GOOD - If a transaction has successfully started or has been updated.
      ArmConstants.STATUS_INVALID - When a transaction is instructed to be stopped, the transaction will be marked invlid and it should never execute again.
      ArmConstants.STATUS_UNKNOWN - When a transaction is first created it will be in an unknown state.
