nested

std::map<std::string, std::map<std::string, std::int32_t>>

Fields

• [Split]Index{32,64}

with the corresponding column type for the offset column of the two collection parent fields. All child fields use the default column types for std::string (Index64 for the principal column, Char for the second column) and std::int32_t (Int32).

Entries

1. Single-element maps, with ascending values for both key and value
2. Empty maps
3. Increasing number of elements in the outer map, with arbitrary lengths of the inner maps

The values can be found in the reference file types.map.nested.json.

Dictionaries

These tests require ROOT dictionaries, which can be generated with the provided Makefile in this directory. This will create a libNestedMap shared object.
