Detailed Description

A callable PolymorphicFunctionObject that is equivalent to the left() function.

Member Function Documentation

template<typename Expr >

BOOST_FORCEINLINE result_of::left<Expr &>::type boost::proto::functional::left::operator() ( Expr &  e ) const

inline

Return the left child of the given binary expression.

Parameters

expr	The expression node.

Precondition

is_expr<Expr>value is true

2 == Expr::proto_arity::value

Returns

proto::left(expr)

Exceptions

nothrow

template<typename Expr >
