inline

Create a file at the given path. Overwrites existing data.

Parameters

columns	Column names, fixes the number of columns for the file
path	Path to the output file
precision	Output floating point precision

Member Function Documentation

template<char Delimiter>

template<typename Arg0 , typename... Args>

void dfe::io_dsv_impl::DsvWriter< Delimiter >::append ( Arg0 &&  arg0, Args &&...  args  )

inline

Append arguments as a new row to the file.

Each argument corresponds to one column. The writer ensures that the number of columns written match the number of columns that were specified during construction.

Note

std::vector arguments are automatically unpacked and each entry is written as a separate column.
