Member Function Documentation

generate()

template<typename T , typename Formatter = use_default_formatter>

std::any dasmig::range_component< T, Formatter >::generate ( const generation_context &  ctx ) const

inlineoverridevirtual

Generate a random value for this component.

Parameters

ctx	Context providing access to previously generated values and a seeded random engine.

Returns

The generated value wrapped in std::any.

Implements dasmig::component.

Definition at line 286 of file entitygen.hpp.

key()

template<typename T , typename Formatter = use_default_formatter>

std::wstring dasmig::range_component< T, Formatter >::key ( ) const

inlineoverridevirtual

Unique key identifying this component (e.g. "name", "age").

Returns

The component key as a wide string.

Implements dasmig::component.

to_string()

template<typename T , typename Formatter = use_default_formatter>

std::wstring dasmig::range_component< T, Formatter >::to_string ( const std::any &  value ) const

inlineoverridevirtual

Convert a generated value to a displayable string.

Parameters

value
