Method Detail

checksum

public static byte[] checksum(java.io.File file)
                       throws java.io.IOException

Creates the MD5 checksum for the given file.

Parameters:

file - the file.

Returns:

findSourceSubdir

public static java.lang.String findSourceSubdir(java.io.File sourceDirectory,
                                                java.io.File grammarFile)

Given the source directory File object and the full PATH to a grammar, produce the path to the named grammar file in relative terms to the sourceDirectory. This will then allow ANTLR to produce output relative to the base of the output directory and reflect the input organization of the grammar files.

Parameters:

sourceDirectory - The source directory File object

grammarFileName - The full path to the input grammar file

Returns:

The path to the grammar file relative to the source directory
