示例1:
void cvct2gdal::CVCT2GDALLayer( VCTLayer * poVCTLayer, OGRLayer * poOGRLayer )
{
OGRFeatureDefn * poOGRFeatDefn =
cvct2gdal::CVCT2GDALFeatureDefn ( & (poVCTLayer->featuredefn ) );
for ( int ifield = 0; ifield < poOGRFeatDefn->GetFieldCount(); ++ifield )
{
poOGRLayer->CreateField ( poOGRFeatDefn->GetFieldDefn ( ifield ) );
}
for (auto ifeat = 0; ifeat != poVCTLayer->GetFeatureCount(); ++ifeat)
{
VCTFeature * poVCTFeat = poVCTLayer->GetFeatureByIndex(ifeat);
//注意：feature在析构时，会将featuredefn也析构
//将featuredefn复制后传入
OGRFeature * poOGRFeat = cvct2gdal::CVCT2GDALFeature ( poVCTFeat, poOGRFeatDefn->Clone());
poOGRLayer->CreateFeature ( poOGRFeat );
//在window下，释放内存会报错
#ifndef WIN32
OGRFeature::DestroyFeature(poOGRFeat);
#endif
}
//在window下，释放内存会报错
#ifndef WIN32
poOGRFeatDefn->Release();
#endif
}示例2:
~OGRCouchDBOneLineLayer()
{
delete poFeature;
if( poFeatureDefn != NULL )
poFeatureDefn->Release();
}
