                                                                            CurrentIterator<WoolBodyToken> tokens)
                                                                     throws LineNumberParseException

Reads the content of a command as a code string. When this method returns, the iterator will be positioned after the command end token.

Parameters:

cmdStartToken - the command start token

tokens - the token iterator positioned after the command start token

Returns:

the content

Throws:

LineNumberParseException - if a parsing error occurs

parseCommandContentName

protected static WoolExpressionCommand.ParseContentResult parseCommandContentName(WoolBodyToken cmdStartToken,
