Method Detail

getContents

public java.lang.String[] getContents()
                               throws java.io.IOException

This method does the actual parsing of the XDC options file. It breaks up the contents into tokens. The following rules apply:

1. Every character may be escaped by placing a backslash ('\') in front of it.
2. Text starting with an (not escaped) hash sign ('#') and ending with a line terminator is considered a comment and is ignored.
3. Text enclosed by double quotes is considered a single token. (The quotes will be stripped by this method.)
4. All whitespace characters (i.e. spaces, tabs, line terminators etc.) which are neither escaped nor part of a comment nor part of a quoted token are treated as token delimiters.

Returns:

An array of the individual tokens contained in this file

Throws:

java.io.IOException
