Struct reverse

boost::proto::functional::reverse — A PolymorphicFunctionObject type that invokes the fusion::reverse() algorithm on its argument.

Synopsis

// In header: <boost/proto/fusion.hpp>


struct reverse :  proto::callable {
  // member classes/structs/unions
  template<typename This, typename Expr> 
  struct result<This(Expr)> :  result< This(Expr const &) > {
  };
  template<typename This, typename Expr> 
  struct result<This(Expr &)> :  fusion::result_of::reverse< Expr > {
  };

  // public member functions
  template<typename Expr> 
    typename fusion::result_of::reverse< Expr >::type operator()(Expr &) const;
  template<typename Expr> 
    typename fusion::result_of::reverse< Expr const >::type 
    operator()(Expr const &) const;
};

Description

A PolymorphicFunctionObject type that invokes the fusion::reverse() algorithm on its argument. This is useful for defining a CallableTransform like reverse(_), which reverses the order of the children of a Proto expression node.

`reverse` public member functions

template<typename Expr> 
  typename fusion::result_of::reverse< Expr >::type 
  operator()(Expr & expr) const;

Returns:

fusion::reverse(expr)

template<typename Expr> 
  typename fusion::result_of::reverse< Expr const >::type 
  operator()(Expr const & expr) const;
