Hi EMF world --
I'm doing some performance tuning of my EMF code. When I change my .genmodel to extend FlatEObjectImpl instead of BasicEObjectImpl, the generated code no longer returns children when I call eContents().
I do also have some custom settings in the ResourceFactoryImpl as follows:
loadOptions.put(XMLResource.OPTION_EXTENDED_META_DATA, extendedMetaData);
loadOptions.put(XMLResource.OPTION_USE_PARSER_POOL, m_parserPool);
loadOptions.put(XMLResource.OPTION_USE_ENCODED_ATTRIBUTE_STY LE, Boolean.TRUE);
loadOptions.put(XMLResource.OPTION_USE_LEXICAL_HANDLER, Boolean.TRUE);
loadOptions.put(XMLResource.OPTION_LAX_FEATURE_PROCESSING, Boolean.TRUE);
loadOptions.put(XMLResource.OPTION_LAX_WILDCARD_PROCESSING, Boolean.TRUE);
loadOptions.put(XMLResource.OPTION_SKIP_ESCAPE, Boolean.TRUE);
loadOptions.put(XMLResource.OPTION_RECORD_UNKNOWN_FEATURE, Boolean.TRUE);
loadOptions.put(XMLResource.OPTION_DEFER_ATTACHMENT, Boolean.TRUE);
loadOptions.put(XMLResource.OPTION_DEFER_IDREF_RESOLUTION, Boolean.TRUE);
loadOptions.put(XMLResource.OPTION_USE_DEPRECATED_METHODS, Boolean.FALSE);
loadOptions.put(XMLResource.OPTION_USE_XML_NAME_TO_FEATURE_M AP, m_nameToFeatureMap);
loadOptions.put(XMLResource.OPTION_CONFIGURATION_CACHE, Boolean.TRUE);
Am I supposed to do something else to tell the FlatEObjectImpl to load its children?
thanks
Tamar

Tamar,
It should still be returning the right (same as before) list:
@Override
public EList<EObject> eContents()
{
if (eContents == null)
{
eContents = *EContentsEList.createEContentsEList(this)*;
}
return eContents;
}
It's a "view" on all the containment references...
