Detailed Description

template<class OSTREAM, class PARAM, class TRAITS = std::char_traits<typename OSTREAM::char_type>>
class ts::IOManipulatorProxy< OSTREAM, PARAM, TRAITS >

I/O manipulator with argument for subclasses of std::basic_ostream.

This class has a similar role as IOManipulator() for functions using one argument.

Sample usage:

namespace ts {
    // The class:
    class TextFormatter: public std::basic_ostream<char>
    {
    public:
        TextFormatter& setMarginSize(size_t margin);
        ....
    };
 
    // The I/O manipulator:
    IOManipulatorProxy<TextFormatter,size_t> margin(size_t size)
    {
        return IOManipulatorProxy<TextFormatter,size_t>(&TextFormatter::setMarginSize, size);
    }
}
 
// Usage:
ts::TextFormatter out;
out << ts::margin(2) << "<foo>" << std::endl;

Template Parameters

OSTREAM	A subclass of std::basic_ostream.
PARAM	The type of the parameter for the manipulator.

inline

Constructor.

Parameters

[in]	func	A pointer to member function in OSTREAM. This method shall take one parameter or type PARAM and return a reference to the OSTREAM object.
[in]	param	The parameter value to pass to the I/O manipulator.
