Classes
struct	EnableDebugOutput
class	SPxOut
	Wrapper for several output streams. A verbosity level is used to decide which stream to use and whether to really print a given message. Regardless of whether the verbosity level is set via a manipulator or via the member function, it is persistent until a new value is set. More...
struct	SPxOut::struct_Verbosity
	helper struct for the output operator More...

Functions
Verbosity manipulator
Manipulators are implemented in a similar way as done for setw(), setprecision(), etc. in the standard library file iomanip. For instance, the non-member function verb(v) returns a struct struct_Verbosity which contains only the verbosity level. Calling SPxOut spxout; spxout << verb( SPxOut::ERROR ) << "This is an error!" << std::endl; passes such a struct to the output operator defined below, which extracts the verbosity level from the struct and passes it to the member function SPxOut::setVerbosity().
SPxOut::struct_Verbosity	verb (const SPxOut::Verbosity &v)
	manipulator to be used in an output statement
SPxOut &	operator<< (SPxOut &stream, const SPxOut::struct_Verbosity &verbosity)
	output operator with verbosity level struct
Output of standard manipulators and other types
We have to define an output operator for many kinds of numeric types here because they can all be more or less casted into each other. When using only a template type, it is not clear what the compiler makes out of it (according to lint).
SPxOut &	operator<< (SPxOut &_spxout, long t)
	Passes instances of type Type to the current stream.
SPxOut &	operator<< (SPxOut &_spxout, unsigned long t)
SPxOut &	operator<< (SPxOut &_spxout, bool t)
SPxOut &	operator<< (SPxOut &_spxout, short t)
SPxOut &	operator<< (SPxOut &_spxout, unsigned short t)
SPxOut &	operator<< (SPxOut &_spxout, int t)
SPxOut &	operator<< (SPxOut &_spxout, unsigned int t)
SPxOut &	operator<< (SPxOut &_spxout, double t)
SPxOut &	operator<< (SPxOut &_spxout, float t)
SPxOut &	operator<< (SPxOut &_spxout, long double t)
SPxOut &	operator<< (SPxOut &_spxout, const void *t)
SPxOut &	operator<< (SPxOut &_spxout, std::ostream &(*manip)(std::ostream &))
	Passes standard manipulators without arguments, like std::endl or std::ios::right to the current stream.
template<typename T >
SPxOut &	operator<< (SPxOut &_spxout, T t)
	Passes everything else to the current stream. In particular, this includes structs corresponding to manipulators with arguments, such as the struct _Setw for the setw() manipulator.
