class for marking output with some text
The principle of this class consists of writing all output first in a userdefined Buffer of type OMBuf. On a flush it spits out at first the userdefined text in squared brackets and afterwards everything from the buffer. An object of this class can be used (almost) exactly like a normal std::cout with the <<-Operator and std::endl.
How to implement in the code of a class with some output:
#include<olb/io> ExampleClass { private: OstreamManager clout; public: ExampleClass() : clout(std::cout,"ExampleClass") {} showOutput() { clout << "where am I?" << std::endl; } }
A call of the function showOutput() will show in terminal:
[ExampleClass] Where am I?
Please note, that the control character \n - in contrast to std::endl - will not force a flush of the outstream. As consequence, the new line won't be prefixed with a user specified text. Other control character might not work either (untested).
