Member Function Documentation

read()

template<class T >

SurveyPxbImage::count_t SurveyPxbImageReader< T >::read ( std::ifstream &  infile, measurements_t &  measurements, SurveyPxbImage::count_t  reserve = 830  )

inline

Reads a file, parses its content and fills the data vector All data after a hash sign (#) is treated as a comment and not read

Parameters

filename	Filename of the file to be read
measurements	Vector containing the measurements, previous content will be deleted
reserve	Initial size of the vector, set with vector::reserve()

Returns

number of succesfully read entries
