◆ GetQuoteChar() [2/2]

const char * OUTPUTFORMATTER::GetQuoteChar ( const char *  wrapee)
virtualinherited

Function GetQuoteChar performs quote character need determination.

It returns the quote character as a single character string for a given input wrapee string. If the wrappee does not need to be quoted, the return value is "" (the null string), such as when there are no delimiters in the input wrapee string. If you want the quote_char to be assuredly not "", then pass in "(" as the wrappee.

Implementations are free to override the default behavior, which is to call the static function of the same name.

Parameters
wrapeeA string that might need wrapping on each end.
Returns
const char* - the quote_char as a single character string, or "" if the wrapee does not need to be wrapped.

◆ GetString()

◆ Print()

int OUTPUTFORMATTER::Print ( int  nestLevel,

Function Print formats and writes text to the output stream.

Parameters
nestLevelThe multiple of spaces to precede the output with.
fmtA printf() style format string.
...a variable list of parameters that will get blended into the output under control of the format string.
Returns
int - the number of characters output.
Exceptions

◆ Quotes()

std::string OUTPUTFORMATTER::Quotes ( const std::string &  aWrapee)
virtualinherited

Function Quotes checks aWrapee input string for a need to be quoted (e.g.

contains a ')' character or a space), and for " double quotes within the string that need to be escaped such that the DSNLEXER will correctly parse the string from a file later.

Parameters
aWrapeeis a string that might need wraping in double quotes, and it might need to have its internal content escaped, or not.
Returns
std::string - whose c_str() function can be called for passing to printf() style functions that output UTF8 encoded s-expression streams.
Exceptions
IO_ERROR,ifthere is any kind of problem with the input string.
