Function Documentation

JConvertToStream()

bool JConvertToStream	(	const int	input,
		std::ifstream *	input2,
		JString *	tempFullName,
		const bool	closeInput
	)

Convert the data from the given file descriptor into an std::ifstream. The location of the file is returned in tempFullName.

This would be unnecessary if libstdc++ provided a stream wrapper for arbitrary file descriptors.

JGetFStreamLength() [1/2]

JSize JGetFStreamLength

(

std::fstream &

theStream

)

JGetFStreamLength() [2/2]

JSize JGetFStreamLength

(

std::ifstream &

theStream

)

Returns the length of the file associated with theStream.

JReadFile() [1/3]

void JReadFile	(	const JString &	fileName,
		JString *	str
	)

Read characters from the std::fstream until the end of the file is reached. These functions takes a JString* because the contents of the file could be very large, and returning a JString requires twice as much memory because of the copy constructor.

These are equivalent to JReadAll() in jStreamUtil.h, except that they are optimized to work with file streams.

JReadFile() [2/3]

void JReadFile	(	std::fstream &	input,
		JString *	str
	)

JReadFile() [3/3]

void JReadFile	(	std::ifstream &	input,
		JString *	str
	)
