Description:
This class allows the management of data streams between a remote and local device. It provides an InputStream and an OutputStream for easily receiving and sending data from/to a remote device. The InputStream stores all retrieved data into its buffer: no data is therefore lost.

Nested Class Summary

protected class	RFCommConnectionImpl.MInputStream An own extension of the classical java InputStream class.
protected class	RFCommConnectionImpl.MOutputStream An own extension of the classical java OutputStream class.

Field Summary

protected RFCommConnectionImpl.MInputStream	inStream The own defined and implemented input stream.
protected RFCommConnectionImpl.MOutputStream	outStream The own defined and implemented output stream.
