sdaiGetEntityExtentBN

This call retrieves an aggregation that contains all instances of the entity given. Technically sdaiGetEntityExtentBN will transform into the following call

    sdaiGetEntityExtent(
            model,
            sdaiGetEntity(
                    model,
                    entityName
                )
        );

Property model

Size: 32 bit / 4 byte (value)
The handle to the model. The model handle is static during its existance. Several models can be opened simultaniously within one session. Different models are always independent, threads are allowed to be running on different models simultaniously.

Property entityName

Size: 32 bit / 4 byte (reference)
...

Example (based on pure API calls)

Here you can find code snippits that show how the API call sdaiGetEntityExtentBN can be used.

#include    "./include/ifcengine.h"
void    GetColumns(int_t model)
{
    int_t   ifcColumnInstances = sdaiGetEntityExtentBN(model, "IFCCOLUMN"),
            noIfcColumnInstances = sdaiGetMemberCount(ifcColumnInstances);
    if (noIfcColumnInstances) {
        for (int_t i = 0; i < noIfcColumnInstances; ++i) {
            char    * globalId = 0, * name = 0, * description = 0;
            int_t   ifcColumnInstance = 0;
            sdaiGetAggrByIndex(ifcColumnInstances, i, sdaiINSTANCE, &ifcColumnInstance);

            sdaiGetAttrBN(ifcColumnInstance, "GlobalId", sdaiSTRING, &globalId);
            sdaiGetAttrBN(ifcColumnInstance, "Name", sdaiSTRING, &name);
