This is a bug fix for the CLI's displayed fiat trade cost
value, which should be trade.volume, not offer.volume. Offer volume
varies with BTC volatility, and the CLI should be showing the trade.volume
value instead, frozen when the contract is made.
Method was added on the false assumption `PaymentAccount#hasMultipleCurrencies()`
would not always return a correct value when a `PaymentAccount` instance is created
via reflection. But `hasMultipleCurrencies()` will work as long as appropriate
PaymentAccount subclasses continue setting their `tradeCurrencies` fields within
their default constructors.
Several payment methods support multiple trade currencies and a selected
trade currency, but the api's payment account creation has not let CLI
users specify them in the json form passed to the `createpaymentacct`
command.
This change adds `tradeCurrencies` and `selectedTradeCurrency` fields
to the appropriate json forms.
Some i18n property values can be used by the API if long strings are
wrapped before written as commments to json payment account forms, or
written to the CLI console.
This change anticipates the addition of the more complex Swift payment
method (PR 5672). PR 5672's i18n property value for key "payment.swift.info"
will be wrapped and appended to the comments of the Swift payment account's
json form.
We can cache an offer payload hash as soon as its `offerFeePaymentTxId`
is set. (The payload hash cannot be calculated until the object can
be transformed into a protobuf message, which requires a non-null
offerFeePaymentTxId.)
Another benefit is removal of the payload hash argument from the
`OfferBookListItem` constructor.
Changes include
- `OfferPayload` Added `transient byte[] hash` field + getter method
(where hash is calculated and cached).
- `OfferBookService` Removed `P2PDataStorage.ByteArray hashOfPayload`
parameter from `OfferBookChangedListener` listener methods
`onAdded` & `onRemoved`. (Hash is cached in `OfferPayload`.)
- `P2PDataStorage` Added null check to `ByteArray` class constructor.
- `OfferBook` Adjusted for change to `OfferBookChangedListener`.
Also removed redundant payload hash null checks.
- `TakeOfferDataModel` and `MarketAlerts` Adjusted for change to
`OfferBookChangedListener`.
- `OfferBookListItem` Removed overloaded constructor with
`@Nullable P2PDataStorage.ByteArray hashOfPayload` parameter.
(Field value is set from cached offer payload hash.)
- `OfferBookViewModelTest` and `OfferMaker` Adjusted test and test fixture:
do not attempt to create offer payloads without an `offerFeePaymentTxId`.
