Detailed Description

Numerical stream adapter that can be assigned to any input stream and allows streaming of numerical values.

In contrast to the default std::istream implementation, this class is able to handle nan and inf values correctly.

This class can be used with different stream "underlays". The underlay provides the actual stream functionality and stores or transmits the data. Currently the binary stream comes in two flavors:

• BinaryStlIstream, which uses stl::istream as underlay
• BinaryBufferIstream, which uses BinaryBufferStreamBase as underlay

This class can be used like any other std::istream, as shown in the

// reads the file that was written in the NumericalOstream example:

ifstream ifs("myfile.txt");
NumericalIstream is(ifs); // create binary stream and attach to file stream

int a;
is >> a;        // a=4

float f, g;
is >> f >> g;   // f=1.234f, g=nan

string s;
is >> s;        // s="This is a string"

uint32 x
is >> hex >> x; // x = 0x12345F;

Constructor & Destructor Documentation

NumericalIstream()

NumericalIstream ( std::istream &  s )

inline

Constructs a NumericalIstream around the specified existing istream.

All input from the NumericalIstream will be relayed to that istream internally. The istream must exist while this NumericalIstream object is existent.
