Function Documentation

bool fileExists

(

const std::string &

pathToFile

)

It checks the existence of the file.

Parameters

pathToFile

Path to a file.

Returns

True if the file exists, otherwise false.

Definition at line 85 of file Utils.cpp.

uint64_t pack	(	const uint32_t &	v1,
		const uint32_t &	v2
	)

It packs two uint32_t numbers to uint64_t data type.

Parameters

v1,v2

The first and second number, respectively.

Returns

Both the numbers packed into the one with double width.

std::pair<uint32_t, uint32_t> unpack

(

const uint64_t &

v

)

It unpacks two uint32_t numbers from uint64_t data type.

Parameters

v	Unsigned integer (uint64_t) containing two packed uint32_t numbers.

Returns

A pair with the unpacked uint32_t numbers.
