  public AccountBasedPurse()

  public Amount getAmountFromBank() throws AmountNotApplicable, PaymentServiceException

Get the amount (balance) in our bank account. The value of the amount can be positive or negative, the latter indicating money owed. This makes sense only for account-based payment systems. The amount is retrieved by asking the bank that maintains the account. Contrast this with the getAmount() method which returns the amount according to the local state of the purse.

This method may have the side-effect of updating the local balance (maintained as part of the local state) of the purse.

Returns:

amount according to the bank account

Throws: AmountNotApplicable

in those systems where it is not possible to check the bank balance

Throws: PaymentServiceException

for other miscellaneous errors
