Detailed Description

Options describing how to interpret or write CSV data.

The CSVOptions structure is used by DataFrame to:

remember whether the CSV file contains an explicit index column,
store the type of each named column,
optionally store the type of the index.

Types are represented using std::type_index and are typically int, double or std::string for this project.

◆ operator[]()

std::type_index & CSVOptions::operator[] ( const std::string & colName )

inline

Access or insert the type entry for a given column name.

If the column is not present in columnTypes, it is inserted with a default placeholder type (typeid(void)) and a reference to that entry is returned.

This is mainly a convenience operator to allow syntax like:

CSVOptions opt;

opt["pt"] = typeid(double);

Parameters

colName Name of the column.

Returns: Reference to the associated std::type_index entry.

Member Data Documentation

◆ columnTypes

std::unordered_map<std::string, std::type_index> CSVOptions::columnTypes

Mapping from column name to its declared C++ type.

The type_index values are usually typeid(int), typeid(double), or typeid(std::string). Missing entries may indicate that the column type has not yet been inferred or set.

Definition at line 42 of file CSVOptions.h.

◆ hasIndex

bool CSVOptions::hasIndex = false

True if the CSV representation contains a separate index column.

Definition at line 33 of file CSVOptions.h.

◆ indexType

std::type_index CSVOptions::indexType = typeid(std::string)

Type used for the DataFrame index.

Default is std::string, which matches the usual label-based index.
