AnonChannel (anonlib 00.21.029-SNAPSHOT API)

All Known Subinterfaces:

IAnonUDPChannel

All Known Implementing Classes:

```
public interface AnonChannel
```
An AnonChannel can be used to send and receive data. There are different types of channels and the transmitted data must match the (proxy-)protocol implied by the type of the channel. A new channel is created via createChannel
It provides an OutputStream and InputStream implementation to send and receive data.

- Field Detail
  - HTTP
```
static final int HTTP
```
    Constant for the channel type: HTTP-Proxy. Such a channel could be used to transmit data which conforms to the HTTP-Proxy-Protocol.

    Constant Field Values
  - SOCKS
```
static final int SOCKS
```
    Constant for the channel type: SOCKS-Proxy. Such a channel could be used to transmit data which conforms to the SOCKS-Proxy-Protocol.
    
    See Also:
    
    Constant Field Values
  - VPN
```
static final int VPN
```
    Constant for the channel type: VPN-like Service. Such a channel could be used to transmit data which conforms to the AN.ON project proprietary VPN-like-Protocol.

    Constant Field Values
  - SMTP
```
static final int SMTP
```
    Constant for the channel type: SMTP-Proxy. Such a channel could be used to transmit data which conforms to the SMTP-Protocol.
    
    See Also:
    
    Constant Field Values
  - TCP
```
static final int TCP
```
    Constant for the channel type: TCP. Such a channel could be used to transmit data to a target Host:Port over TCP.
    
    See Also:
    
    Constant Field Values
  - UDP
```
static final int UDP
```
    Constant for the channel type: UDP. Such a channel could be used to transmit data to a target Host:Port using UDP. Note: the client automatically select the best suited anonymisation/transport protocol for transporting UDP packets based on the features the currently chosen cascade offers.
    
    See Also:
    
    Constant Field Values
  - UDP_OVER_TCP
```
static final int UDP_OVER_TCP
```
    Constant for the channel type: UDP. Such a channel could be used to transmit data to a target Host:Port using UDP. Note: this channel will use the TCP-based anonymisation protocol.
    
    See Also:
    
    Constant Field Values
  - UDP_OVER_UDP
```
static final int UDP_OVER_UDP
```
    Constant for the channel type: UDP. Such a channel could be used to transmit data to a target Host:Port using UDP. Note: this channel will use the UDP-based anonymisation protocol.

- Method Detail
  - getInputStream
```
java.io.InputStream getInputStream()
```
    The returned InputStream could be used to receive data.
    
    Returns:
    
    InputStream, useful for receiving data
  - getOutputStream
```
java.io.OutputStream getOutputStream()
```
    The returned OutputStream could be used to send data.
    
    Returns:
    
    OutputStream, useful for sending data
  - getOutputBlockSize
```
int getOutputBlockSize()
```
    Returns a value that indicates the current optimum size of data to write. Because often anon services transport the data fragmented into fixed sized packets for optimum performance it may be good to send data according to the packet size to avoid unneccessary overheads.
    
    Returns:
    
    the current optimum size for output data. If 1 is returned the size does not matter.
  - close
```
void close()
```
    Closes the channel and releases all resources used.
  - isClosed
```
boolean isClosed()
```
    Returns if the channel is already closed, i.e. no data can be sent / recieved any more on this channel.
    
    Returns:
    
    true, if the channel is already closed
