Example 2: C++ API Code to Retrieve Polygons

void FindPolygons( seObject current_obj ){

seIterator iterator;

seObject child_obj;

SE_DRM_Class drm_type;

current_obj.getComponentIterator( iterator );

while(!iterator.isCompleted()){

iterator.getNext( child_obj );

drm_type = child_obj.getDRMClass();

if( drm_type == SE_DRM_CLS_POLYGON ){

/* process the polygon object */

}

else{

/* prune search paths that won’t result in finding <Polygons> */

if( SE_ShortestAggPath[drm_type][SE_DRM_CLS_POLYGON] != -1 )

{

FindPolygons( child_obj ); /* recurse down the transmittal tree */

}
