Constructor Detail

AtpConnectionImpl

public AtpConnectionImpl(java.net.URL url)
                  throws java.io.IOException

Create a new instance of this class.

Parameters:

url - a destination URL to which the application connects. The protocol is "atp".

Method Detail

close

public void close()
           throws java.io.IOException

connect

public void connect()
             throws java.io.IOException

Make a comminucation link with the destination.

Overrides:

connect in class java.net.URLConnection

Throws:

java.io.IOException - if can not make a communication link.

getHeaderField

public java.lang.String getHeaderField(java.lang.String key)

Overrides:

getHeaderField in class java.net.URLConnection

getInputStream

public java.io.InputStream getInputStream()
                                   throws java.io.IOException

Get an input stream of the communication link.

Overrides:

getInputStream in class java.net.URLConnection

Returns:

an input stream.

Throws:

java.io.IOException - if the communication link has a problem.

getMIC

public byte[] getMIC()

getOutputStream

public java.io.OutputStream getOutputStream()
                                     throws java.io.IOException

Get an output stream of the communication link. If the destination is out of firewall and a proxy is specified, an output stream connected to the proxy will be returned, The stream will add the destination atp address to top of an output data. The proxy reads the address, takes it away and forewards the ramained data to the specified destination.

Overrides:

getOutputStream in class java.net.URLConnection

Returns:

an output stream.

Throws:

java.io.IOException - if the communication link has a problem.

getProperty

public java.lang.String getProperty(java.lang.String key)

getReasonPhase

public java.lang.String getReasonPhase()

getStatusCode

public int getStatusCode()
