Global Functions
bool mrpt::io::vectorToBinaryFile( const std::vector<uint8_t>& vec, const std::string& fileName )
Saves a vector directly as a binary dump to a file:
Returns:
Returns false on any error, true on everything OK.
See also:
bool mrpt::io::loadBinaryFile( std::vector<uint8_t>& out_data, const std::string& fileName )
Loads a entire file as a vector of bytes.
Returns:
Returns false on any error, true on everything OK.
See also:
bool mrpt::io::loadTextFile( std::vector<std::string>& o, const std::string& fileName )
Loads a text file as a vector of string lines.
Returns:
Returns false on any error, true on everything OK.
See also:
std::string mrpt::io::file_get_contents(const std::string& fileName)
Loads an entire text file and return its contents as a single std::string.
Relying on C++17 RVO to return a string without worring on return-by-value of big objects.
Parameters:
std::runtime_error |
On any read error. |

bool mrpt::io::vectorToTextFile( const std::vector<float>& vec, const std::string& fileName, bool append = false, bool byRows = false )
A useful function for debugging, which saves a numeric std::vector as a plain-text file compatible with MATLAB.
Returns:
Returns false on any error, true on everything OK.
bool mrpt::io::vectorToTextFile( const std::vector<double>& vec, const std::string& fileName, bool append = false, bool byRows = false )
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
bool mrpt::io::vectorToTextFile( const std::vector<int>& vec, const std::string& fileName, bool append = false, bool byRows = false )
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

template <class EIGEN_MATRIX> bool mrpt::io::vectorToTextFile( const EIGEN_MATRIX& vec, const std::string& fileName )
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
bool mrpt::io::vectorNumericFromTextFile( std::vector<double>& vec, const std::string& fileName, const bool byRows = false )
Load a numeric std::vector<double> from a text file (compat.
with MATLAB)
Returns:
Returns false on any error, true on everything OK.
