SgGameReader Class Reference

#include <SgGameReader.h>

List of all members.

Detailed Description

Read file with SGF data.

Properties are read sequentially, therefore GM and SZ properties have to be before any point value properties, because they are required to parse the point values. According to the SGF standard, the order or properties is arbitrary and there exist SGF files, which have the GM and SZ property after point properties (like AB, AW) in the root node. To fix this, all properties of a node would have to be read and GM and SZ handled first before parsing any other property values.

void SgGameReader::HandleProperties ( SgNode node,
const RawProperties properties,
int &  boardSize,
SgPropPointFmt fmt 
) [private]

Create SgProp instances and add them to node.

The only properties that are interpreted by the reader are SZ (board size) and GM (point format, because they must be handled before all other root node properties to parse points correctly.
