Detailed Description

template<typename MinType, typename MaxType>
class arg_router::policy::min_max_count_t< MinType, MaxType >

Exposes the number of tokens the owning node will consume.

It also checks that there are enough pending tokens available to reach the minimum in the pre-parse phase.

Template Parameters

MinType	Compile-time integral constant value representing the minimum
MaxType	Compile-time integral constant value representing the maximum

maximum_count()

template<typename MinType , typename MaxType >

constexpr static std::size_t arg_router::policy::min_max_count_t< MinType, MaxType >::maximum_count ( )

inlinestaticconstexprnoexcept

Returns

Maximum count value.

minimum_count()

template<typename MinType , typename MaxType >

constexpr static std::size_t arg_router::policy::min_max_count_t< MinType, MaxType >::minimum_count ( )

Returns

Minimum count value.

inline

Copies an appropriate amount of tokens from args to result.

This policy performs label and bulk value token processing. If the owning node is named, then the first token is expected to match, if not then false is returned immediately.

Then up to maximum_count()

Returns

the

• tokens are processed. If the maximum available is less than minimum_count(), a parse error will occur.

Template Parameters

ProcessedTarget	processed_target payload type
Parents	Pack of parent tree nodes in ascending ancestry order

Parameters

tokens	Currently processed tokens
processed_target	Previously processed parse_target of parent node, or empty is there is no non-root parent
target	Pre-parse generated target
parents	Parent node instances

Returns

Either true if successful, or a multi_lang_exception if the minimum count is not reached
