public InetAddress getServerInetAddress()

Gets the address of the server or null if not connected.

Specified by:

getServerInetAddress in interface ClientCommunicationInterface

getClientDNSName

public String getClientDNSName()

Gets the DNS name of this client connection. A return value of "null" indicates that there is no DNS name found.

Specified by:

getClientDNSName in interface SocketNameInterface

getClientIPAddress

public String getClientIPAddress()

Gets the IP address of this client connection (as 1.2.3.4), or return "0.0.0.0" if disconnected and the address never has been retrieved.

Specified by:

getClientIPAddress in interface SocketNameInterface

receiveTransaction

public byte[] receiveTransaction()
                          throws IOException

Reads a transaction from the client. This call is blocking until the transaction has been read.

Specified by:

receiveTransaction in interface ClientCommunicationInterface

Returns:

null if the socket is closed.

Throws:

IOException

receiveTransaction

public byte[] receiveTransaction(Object[] isCompressed)
                          throws IOException

Reads a transaction from the client. This call is blocking until the transaction has been read.

Specified by:

receiveTransaction in interface ClientCommunicationInterface

Returns:

null if the socket is closed.

Throws:

IOException

sendTransaction

public void sendTransaction(byte[] data)
                     throws IOException

Sends a transaction to the client. This call is blocking until the transaction has been sent.

Specified by:

sendTransaction in interface ClientCommunicationInterface

Throws:

IOException
