try:

shapeObj shape2 = m_Layer.getFeature( featIndex ,-1);

and you can use featIndex to access the list where features are stored
like you would if you were accessing an array.
I don't think you even need to query the layer, just use getFeature().
Inline layers do not need to opened.

As of deleting that is not supported.
