Usage

Simply add the following code on your Java Application.

WsNemTransactionMonitor.networkName("testnet").host("23.228.67.85").port("7890").wsPort("7778")
	.addressToMonitor("MDYSYWVWGC6JDD7BGE4JBZMUEM5KXDZ7J77U4X2Y") // address to monitor
	.subscribe(io.nem.utils.Constants.URL_WS_TRANSACTIONS, new CustomTransactionMonitorHandler1()) // multiple subscription and a handler
	.subscribe(io.nem.utils.Constants.URL_WS_UNCONFIRMED, new CustomTransactionMonitorHandler2())
	.monitor(); // trigger the monitoring process

You can also monitor multiple addresses

WsNemTransactionMonitor.networkName("testnet").host("23.228.67.85").port("7890").wsPort("7778")
	.addressesToMonitor("MDYSYWVWGC6JDD7BGE4JBZMUEM5KXDZ7J77U4X2Y","MDYSYWVWGC6JDD7BGE4JBZMUED7BGE4JBD") // address to monitor
	.subscribe(io.nem.utils.Constants.URL_WS_TRANSACTIONS, new CustomTransactionMonitorHandler1()) // multiple subscription and a handler
	.subscribe(io.nem.utils.Constants.URL_WS_UNCONFIRMED, new CustomTransactionMonitorHandler2())
	.monitor(); // trigger the monitoring process

Custom Transaction Monitor

You can create your own handler to handle the incoming payload.

public class CustomTransactionMonitor extends AbstractTransactionMonitorHandler {
	@Override
	public Type getPayloadType(StompHeaders headers) {
		return String.class;
	}
	@Override
	public void handleFrame(StompHeaders headers, Object payload) {
		System.out.println(payload.toString()); // handle the payload.
	}
}

WsNemTransactionMonitor.networkName("testnet").host("23.228.67.85").port("7890").wsPort("7778")
	.addressToMonitor("MDYSYWVWGC6JDD7BGE4JBZMUEM5KXDZ7J77U4X2Y")
	.subscribe(io.nem.utils.Constants.URL_WS_TRANSACTIONS, new CustomTransactionMonitorHandler2())
	.monitor();
