Class LibraryAdapter

java.lang.Object
  tuwien.auto.calimero.serial.LibraryAdapter

public abstract class LibraryAdapter
extends java.lang.Object

Adapter to access a serial communication port using some serial I/O library.

Subtypes of this class implementing the access to a specific library have to declare a public constructor expecting a String and an int argument:
Ctor(String portID, int baudrate)
Invoking this constructor will open the serial port according the supplied arguments.

After closing a library adapter, method behavior is undefined.

Field Summary

protected static LogService

logger The same logger as used for the FT1.2 connection.

Constructor Summary

protected

LibraryAdapter() Creates a new library adapter.

Method Summary

abstract void	close() Closes an open serial port.
int	getBaudRate() Returns the currently used baud rate.
abstract java.io.InputStream	getInputStream() Returns the input stream for the opened serial communication port.
abstract java.io.OutputStream	getOutputStream() Returns the output stream for the opened serial communication port.
protected java.lang.Object	invoke(java.lang.Object obj, java.lang.String method, java.lang.Object[] args) Invokes method name on object obj with arguments args.
void	setBaudRate(int baudrate) Sets a new baud rate for this connection.

logger

protected static final LogService logger

The same logger as used for the FT1.2 connection.

Constructor Detail

LibraryAdapter

protected LibraryAdapter()

Creates a new library adapter.

Method Detail

close

public abstract void close()
                    throws java.io.IOException

Closes an open serial port.

Throws:

java.io.IOException - on error during close

getBaudRate

public int getBaudRate()

Returns the currently used baud rate.

Returns:

baud rate in Bit/s

getInputStream

public abstract java.io.InputStream getInputStream()

Returns the input stream for the opened serial communication port.

Subsequent invocations might return the same or a new stream object.

Returns:

InputStream

getOutputStream

public abstract java.io.OutputStream getOutputStream()

Returns the output stream for the opened serial communication port.

Subsequent invocations might return the same or a new stream object.

Returns:

OutputStream

invoke

protected java.lang.Object invoke(java.lang.Object obj,
                                  java.lang.String method,
                                  java.lang.Object[] args)
                           throws java.lang.NoSuchMethodException,
                                  java.lang.IllegalAccessException,
                                  java.lang.reflect.InvocationTargetException

Arguments wrapped in an object of type Integer are replaced with the primitive int type when looking up the method name.

Parameters:

obj - object on which to invoke the method

method - method name

args - list of arguments

Returns:

the result of the invoked method

Throws:

java.lang.NoSuchMethodException

java.lang.IllegalAccessException

java.lang.reflect.InvocationTargetException

setBaudRate

public void setBaudRate(int baudrate)

Sets a new baud rate for this connection.

Parameters:

baudrate - requested baud rate [Bit/s], 0 < baud rate
