Class SecsISocketManager

java.lang.Object

com.ergotech.secs.PortManager

com.ergotech.secs.SecsISocketManager

All Implemented Interfaces:

java.lang.Runnable

public class SecsISocketManager
extends PortManager
implements java.lang.Runnable

This object supports execution of SECSI over a socket link. It is used primarily in simulation and testing but also serves as an example of how to create alternate socket managers.

Constructor Detail

SecsISocketManager

public SecsISocketManager(int portNumber,
                          int baudRate)
                   throws java.io.IOException

Creates the SECS1 socket manager. There is some effort to simulate SECSI so that port numbers are assumed to be zero and one. The connection with port number zero will make an active socket connection to the socket manager with the port number one. In all case the port number used for the socket connection is 7442.

Parameters:

portNumber - port number zero creates an active connection to port number one

baudRate - ignored, but here so that it looks like a serial link.

Throws:

java.io.IOException

SecsISocketManager

public SecsISocketManager(int portNumber,
                          java.lang.String connectionId)
                   throws java.io.IOException

Creates the SECS1 socket manager. This is a required constructor used by SessionManager.

Throws:

java.io.IOException

See Also:

SessionManager.getSessionManager(int, java.lang.String, int, int, boolean, java.lang.Class)

Method Detail

available

public int available()
              throws java.io.IOException

Returns the number of bytes available.

Specified by:

available in class PortManager

Returns:

is.available()

Throws:

java.io.IOException

close

public void close()
           throws java.io.IOException

Close the socket manager. This closes all the streams and the socket.

Specified by:

close in class PortManager

Throws:

java.io.IOException

read

public int read(byte[] b,
                int off,
                int len)
         throws java.io.IOException

Read the socket.

Specified by:

read in class PortManager

Throws:

java.io.IOException

See Also:

read

run

public void run()

runs the server and waits for input on the selected port. When a connection is accepted it will start processing on that connection. In general it will create a new instance of this object to do that. For the first connection it simply configures this object and registers it.

Specified by:

run in interface java.lang.Runnable

toString

public java.lang.String toString()

Return the string representation of this object.

Overrides:

toString in class java.lang.Object

write

public void write(byte[] b)
           throws java.io.IOException

Writes the array to the socket.

Specified by:

write in class PortManager

Throws:

java.io.IOException
