Class CommandlineParser

java.lang.Object
  ccs.utils.CommandlineParser

public class CommandlineParser
extends java.lang.Object

A parser which converts a command-line string into a sequence of parameters, suitable for passing to Runtime.exec. It has three parse rules:

1. Anything inside double quotes "like this" is part of a single parameter. The quote marks are also part of the parameter (they are not stripped). This allows e.g. Windows filenames which have spaces in them to be parsed correctly if quoted, as Windows specifies.
2. Any whitespace not in "double quotes" is a parameter separator. Doubled spaces have no effect; empty parameters are not permitted.
3. any instance of the character '@' is replaced with a supplied, fixed String. This allows, for example, a variable filename to be embedded in the commandline in whatever way is required. The '@' character is escaped by repeating it: "@@" becomes "@" and not the fixed string twice.
