getSpatialWeightsFileInfo()

static void te::sa::SpatialWeightsExchanger::getSpatialWeightsFileInfo ( std::string  pathFileName, std::string &  dataSetName, std::string &  attrName  )

static

Function used to get information of how a Spatial Weights was generated.

Parameters

pathFileName	Path and file name (with extension) with Spatial Weights information.
dataSetName	Information about the dataset used to generate this file.
attrName	Information about the attribute used to generate this file.

Returns

A Valid gpm pointer if the file was correctly readed and null pointer in other case.
