builder module¶

namespace cauldron¶

template <class Object, class... Value>

class Builder¶

#include <builder.h>

Strategy which generates Object instances with constructor arguments generated from corresponding strategies.

Note

Object should have appropriate constructor so types and order of passed strategies agree with types and order of constructor parameters or compile-time error will arise.

Template Parameters

Object: type of objects generated by strategy.

Inherits from cauldron::CloneHelper< Object, Builder< Object, Value... > >

Public Functions

Builder(const cauldron::Strategy<Value>&... strategy)¶

Parameters

strategy: strategy to generate constructor arguments from.

Builder(const Builder<Object, Value...> &builder)¶: Default copy constructor doesn’t fit since we’re using std::unique_ptr as class members which is not copyable.

Object operator()() const¶: Generates pseudo-random Object instance.

Private Functions

template <std::size_t... Indices>
Object produce(const std::tuple<std::unique_ptr<cauldron::Strategy<Value>>...> &strategies, std::index_sequence<Indices...>) const¶: Helper function for unpacking Builder::strategies_ tuple into variadic Strategy instances.

Object produce(const std::unique_ptr<cauldron::Strategy<Value>>&... strategy) const¶: Helper function for producing values from variadic Strategy instances.

std::tuple<std::unique_ptr<cauldron::Strategy<Value>>...> clone_strategies() const¶

template <std::size_t... Indices>
std::tuple<std::unique_ptr<cauldron::Strategy<Value>>...> clone_strategies(const std::tuple<std::unique_ptr<cauldron::Strategy<Value>>...> &strategies, std::index_sequence<Indices...>) const¶: Helper function for unpacking Builder::strategies_ tuple into variadic Strategy instances.

std::tuple<std::unique_ptr<cauldron::Strategy<Value>>...> clone_strategies(const std::unique_ptr<cauldron::Strategy<Value>>&... strategy) const¶: Helper function for cloning variadic Strategy instances.
