[eVista]EntityHandle, ModelEntity, ModelEntityBean, MTIObject

item_handle to EntityHandle

import com.sdrc.metaphase.enterprise.es.base.Accessor;

Accessor accessor = (Accessor)esManager.getProcessor("base.Accessor", esSession);

EntityHandle entity_handle = accessor.reconstructEntityHandle(item_handle);

EntityHandle to MTIObject

import COM.metaphasetech.mot.MTIObject;

MTIObject obj = ProcessorImpl. getMTIObject(entity_handle);

item_handle to MTIObject

MTIObject obj = ProcessorImpl.getMTIObject(item_handle);

item_handle to ModelEntity

import com.sdrc.metaphase.enterprise.es.base.ModelEntity;

ModelEntity

   Accessible

Accessor accessor = (Accessor)esManager.getProcessor(“base.Accessor”, esSession);

EntityHandle entity_handle = accessor.reconstructEntityHandle(item_handle);

Accessible model_entity = accessor.get(entity_handle);

MTIObject to ModelEntity

import COM.metaphasetech.mot.MTIObject;

import com.sdrc._metaphase.enterprise.es_evista.base.ModelEntity;

MTIObject obj = …;

ModelEntity me = new ModelEntity(obj);

How to get Attribute from MTIObject

MTIObject obj;

Object partNumber = obj.getInternalObject().getAttribute("PartNumber");

How to get Attribute from EntityHandle

Frist, convert EntityHandle to ModelEntity:

ModelEntity model_entity = accessor.get(entity_handle);

Second, convert ModelEntity to ModelEntityBean:

ModelEntityBean bean = ModelEntityBeanFactory.createModelEntityBean(action_context, arguments, model_entity);

At last, get Attribute from bean:

Object partNumber = bean.getItemAttributeValue("PartNumber");

 

ObjectSet from cs to bs

MTIObjectVector is returned while call cs;

ArrayList list = new ArrayList();

For each MTIObject item in MTIObjectVector

{

convert item to ModelEntity(way is involved before);

add the ModelEntity to list;

}

 

Use system action chain to convert list to ModelEntityContainerBean;

// chain id is “eds_mwau_act_chain_prepare_collection_for_display”
