Detailed Description

Used for text file output.

Writes through a sibling temp file and atomically renames onto the final target in Finish(). A crash, throw, or power loss between construction and Finish() leaves the final target byte-identical to its prior contents – never truncated. Finish() must be called to save; otherwise the destructor discards the temp file and leaves the target untouched.

It is about 8 times faster than STREAM_OUTPUTFORMATTER for file streams.

Constructor & Destructor Documentation

◆ FILE_OUTPUTFORMATTER()

FILE_OUTPUTFORMATTER::FILE_OUTPUTFORMATTER	(	const wxString &	aFileName,
		const wxChar *	aMode = wxT( "wt" ),
		char	aQuoteChar = '"' )

Parameters

aFileName	is the full filename to open and save to as a text file.
aMode	is what you would pass to wxFopen()'s mode, defaults to wxT( "wt" ) for text files that are to be created here and now.
aQuoteChar	is a char used for quoting problematic strings (with whitespace or special characters in them).

Exceptions

IO_ERROR if the sibling temp file cannot be created.

Member Function Documentation

◆ Finish()

bool FILE_OUTPUTFORMATTER::Finish ( )

overridevirtual

Flushes the temp file to disk and atomically renames it over the final target path.

After a successful return the final target contains the bytes written. A failure before the rename leaves the original contents intact; a directory-flush failure after the rename throws even though the new contents are already visible, because only their durability is in doubt.

Finish() must be called at most once. Calling it again (whether the commit succeeded or failed) is a programming error.

Returns: true on successful commit.

Exceptions

IO_ERROR if fsync, close, rename, or the directory flush fails.

◆ GetQuoteChar() [1/2]

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.

◆ GetQuoteChar() [2/2]

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

staticprotectedinherited

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.

◆ Indent()

int OUTPUTFORMATTER::Indent ( int aNestLevel )

inherited

Write the leading whitespace for a nesting level, with no other output.

Parameters

aNestLevel The multiple of spaces to write.

Returns: int - the number of characters output.

Exceptions

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

◆ Print() [1/2]

int OUTPUTFORMATTER::Print	(	const char *	fmt,

inherited

Format and write text to the output stream.

Parameters

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.

◆ Print() [2/2]

int OUTPUTFORMATTER::Print	(	int	nestLevel,
		const char *	fmt,
			... )

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

◆ 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.
