Parses transaction objects to a higher-level view.
Takes a transaction metadata object (as returned by a casinocoin-libjs response) and computes the balance changes that were caused by that transaction.
The return value is a javascript object in the following format:
{ CASINOCOINADDRESS: [BALANCECHANGE, ...], ... }
where BALANCECHANGE
is a javascript object in the following format:
{
counterparty: CASINOCOINADDRESS,
currency: CURRENCYSTRING,
value: DECIMALSTRING
}
The keys in this object are the Casinocoin [addresses] whose balances have changed and the values are arrays of objects that represent the balance changes. Each balance change has a counterparty, which is the opposite party on the trustline, except for CSC, where the counterparty is set to the empty string.
The CURRENCYSTRING
is 'CSC' for CSC, a 3-letter ISO currency code, or a 160-bit hex string in the [Currency format].
Takes a transaction metadata object and computes the changes in the order book caused by the transaction. Changes in the orderbook are analogous to changes in [Offer
entries] in the ledger.
The return value is a javascript object in the following format:
{ CASINOCOINADDRESS: [ORDERCHANGE, ...], ... }
where ORDERCHANGE
is a javascript object with the following format:
{
direction: 'buy' | 'sell',
quantity: {
currency: CURRENCYSTRING,
counterparty: CASINOCOINADDRESS, (omitted if currency is 'CSC')
value: DECIMALSTRING
},
totalPrice: {
currency: CURRENCYSTRING,
counterparty: CASINOCOINADDRESS, (omitted if currency is 'CSC')
value: DECIMALSTRING
},
makerExchangeRate: DECIMALSTRING,
sequence: SEQUENCE,
status: ORDER_STATUS,
expirationTime: EXPIRATION_TIME (omitted if there is no expiration time)
}
The keys in this object are the Casinocoin [addresses] whose orders have changed and the values are arrays of objects that represent the order changes.
The SEQUENCE
is the sequence number of the transaction that created that create the orderbook change.
The CURRENCYSTRING
is 'CSC' for CSC, a 3-letter ISO currency code, or a 160-bit hex string in the [Currency format].
The makerExchangeRate
field provides the original value of the ratio of what the taker pays over what the taker gets (also known as the "quality").
The ORDER_STATUS
is a string that represents the status of the order in the ledger:
"created"
: The transaction created the order. The values ofquantity
andtotalPrice
represent the values of the order."partially-filled"
: The transaction modified the order (i.e., the order was partially consumed). The values ofquantity
andtotalPrice
represent the absolute value of change in value of the order."filled"
: The transaction consumed the order. The values ofquantity
andtotalPrice
represent the absolute value of change in value of the order."cancelled"
: The transaction canceled the order. The values ofquantity
andtotalPrice
are the values of the order prior to cancellation.
The EXPIRATION_TIME
is an ISO 8601 timestamp representing the time at which the order expires (if there is an expiration time).
