How to use

There is three ways to init BlockObserver

Default way, use embedded blockchain observers

let blockObserver = BlockObserver(assets: [.ethereum, .ripple])
blockObserver.addObserver(for: "0xB29f7E1AB952CF2770D56712e4667680F55359eb", asset: .ethereum)

Use your own Blockchain Observers

let myEhtereumObserver: BlockchainObserverInterface = RippleBlockchainObserver()
let myRippleObserver: BlockchainObserverInterface = EthereumBlockchainObserver()
let buffer: TransactionsBufferInterfce = TransactionsBuffer(capacity: 100)
let looger: Logger = PrintLoger()
let blockObserver = BlockObserver(blockchainsObservers: [myEhtereumObserver, myRippleObserver],
                                  buffer: buffer,
                                  logger: looger)
myEhtereumObserver.delegate = blockObserver
myRippleObserver.delegate = blockObserver

If you do not create own .init in your blockchain observers, you can use simpler init

let buffer: TransactionsBufferInterfce = TransactionsBuffer(capacity: 100)
let looger: Logger = PrintLoger()
let blockObserver = BlockObserver(blockchainsObservers: [RippleBlockchainObserver.self, RippleBlockchainObserver.self],
buffer: buffer,
logger: looger)

Add observer

blockObserver.addObserver(for: "0xB29f7E1AB952CF2770D56712e4667680F55359eb", asset: .ethereum)

Remove observer

blockObserver.removeObserver(for: "0xB29f7E1AB952CF2770D56712e4667680F55359eb", asset: .ethereum)

That's all, now you can check your transactions when you want:

print(blockObserver.transactions)
