Class DataStreamConvert

java.lang.Object

util.CommandLineParser

io.DataStreamConvert

public class DataStreamConvert
extends CommandLineParser

Reads a java binary data stream and converts it into ascii data. It is\ essential to state the '-format' command line switch. This switch regulates which and how many primitive data types should be read from the binary file and put into a single line in the ascii file. Known primitive identifier are

• b:Reads a binary byte.
• s:Reads a binary short.
• c:Reads a binary char
• i:Reads a binary int
• l:Reads a binary long
• f:Reads a binary float
• d:Reads a binary double
• S:Reads a binary UTF string representation.

No modifier for reading a binary boolean is given. Binary booleans are writtn like bytes and should thus be read in as bytes as well. As an example, a -format 'f d f i' tries to read a float a double, a float again and an integer from the binary file. If no exception is thrown, the ascii representation of these numbers are writtn to the output file.
