Constructor Detail

AEFileOutputStream

public AEFileOutputStream(java.io.OutputStream os)

Creates a new instance of AEOutputStream.

Parameters:

os - an output stream, e.g. from new BufferedOutputStream(new FileOutputStream(File f).

Method Detail

writePacket

public void writePacket(AEPacketRaw ae)
                 throws java.io.IOException

Writes the packet out as sequence of address/timestamp's, just as they came as input from the device. The notion of a packet is discarded to simplify later reading an input stream from the output stream result.

java.io.IOException

writeHeaderLine

public void writeHeaderLine(java.lang.String s)
                     throws java.io.IOException
