Constructor Detail

MakeLegacy

public MakeLegacy()

Method Detail

main

public static void main(java.lang.String[] args)

Command-line access to conversion process.

Parameters:

args - The array of Strings passed as command-line arguments. The arguments are:

• input filename - full path and name of .con file to convert.
• output filename - full path and name of .dat file produced.

make

public static void make(java.lang.String inputFilename,
                        java.lang.String outputFilename)

Performs actual conversion of CON files to DAT files.

Parameters:

inputFilename - Full path and name of CON file to process.

outputFilename - Full path and name of DAT file to produce.

skipComments

public static int skipComments(java.io.BufferedInputStream fileIn)

Skips over comment lines in the language files. The human-readable files can have comment lines, indicated by the ':' colon character, or the COMMENT constant in MakeLanguage256. This should return first non-comment character of the first non-comment line as an int.

To be explicit: the method halts only when one of the following is met:

1. A carriage return is followed by a non-comment non-linefeed character or
2. A linefeed followed by a non-comment non-carriage return character.

In both cases, the ASCII/Unicode characters for CR, LF are used. This should work for Apple Macintosh, Windows and Unix systems.

Parameters:

fileIn - BufferedInputStream to the file being read from.

Returns:

readBuffer[1] An int, the first character of the next non-comment line.

skipComments

public static java.lang.String skipComments(java.io.BufferedReader fileIn)

Skips over comment lines in the language files. The human-readable files can have comment lines, indicated by the ':' colon character, or the COMMENT constant in MakeLanguage256. This should return first non-comment character of the first non-comment line as an int.

Parameters:

fileIn - BufferedInputStream for the file being read.

Returns:

toReturn String containing the first non-comment line.
