void ConfigMap::readParams ( std::istream & paramStream )

Reads parameter name/value pairs from an input stream, until end-of-stream is encountered.

Each pair should be on a line by itself, with whitespace between the name and value.

Parameters:

paramStream the stream from which to read parameters
