◆ GetQuoteChar() [1/2]

Perform quote character need determination according to the Specctra DSN specification.

Parameters

wrapee	A string that might need wrapping on each end.
quote_char	A single character C string which provides the current quote character, should it be needed by the wrapee.

Returns: the quote_char as a single character string, or "" if the wrapee does not need to be wrapped.

◆ GetQuoteChar() [2/2]

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

virtualinherited

Perform 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

wrapee A string that might need wrapping on each end.

Returns: the quote_char as a single character string, or "" if the wrapee does not need to be wrapped.

◆ Print()

int OUTPUTFORMATTER::Print	(	int	nestLevel,

inherited

Format and write text to the output stream.

Parameters

nestLevel	The multiple of spaces to precede the output with.
fmt	A 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

IO_ERROR,if there is a problem outputting, such as a full disk.

◆ Quotes()

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

virtualinherited

Check 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

aWrapee is a string that might need wrapping in double quotes, and it might need to have its internal content escaped, or not.

Returns: a 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,if there is any kind of problem with the input string.
