How do you use PxStringTable?

This is a simple question. How do I get string data out of a PxStringTable. How do I use the PxStringTable. Please can someone help me with this, its such a simple question someone must know how.

Thanks,
David

mStringTable = &PxStringTableExt::createStringTable( getFoundation().getAllocator() );

PxDefaultFileInputData data(getFilename("file.repx"));

RepXCollection* collection = createCollection(data, getFoundation().getAllocator());
addObjectsToScene(*collection, physics, getFramework().getCooking(), scene, mStringTable);
collection->destroy();

PxActor* actors[512];
scene.getActors(PxActorTypeSelectionFlag::eRIGID_DYNAMIC, &actors[0],512);
PxU32 nbActors = scene.getNbActors(PxActorTypeSelectionFlag::eRIGID_DYNAMIC);

for (PxU32 i =0; i < nbActors; i++)
{
	actors[i]->getName();
	
}
