Class ERXModelGroup

java.lang.Object
  com.webobjects.eoaccess.EOModelGroup
      er.extensions.ERXModelGroup

public class ERXModelGroup

extends EOModelGroup

The reason that this model group is needed is because the regular EOModelGroup will fail to load a model if it has an entity name conflict. While normally this could be considered a 'good thing' in the case of EOPrototypes multiple EOModels might all need there own prototype entities (in fact EOM requires it). This model group subclass will only print warning messages when duplicate entity names are found.

Method Summary

void	addModel(EOModel eomodel) This implementation will load models that have entity name conflicts, removing the offending entity.
void	checkInheritanceRelationships() Corrects a strange EOF inheritance issue where if a model gets loaded and an entity that has children located in a different model that hasn't been loaded yet will not be setup correctly.
static EOModelGroup	modelGroupForLoadedBundles() The only reason this method is needed is so our model group subclass is used.

Method Detail

modelGroupForLoadedBundles

public static EOModelGroup modelGroupForLoadedBundles()

The only reason this method is needed is so our model group subclass is used. Other than that it does the exact same thing as EOModelGroup's implementation.

Returns:

ERXModelGroup for all of the loaded bundles

addModel

public void addModel(EOModel eomodel)

This implementation will load models that have entity name conflicts, removing the offending entity. The reason this is needed is because multiple models might have JDBC prototype entities which would cause problems for the model group.

Parameters:

eomodel - model to be added

checkInheritanceRelationships

public void checkInheritanceRelationships()

Corrects a strange EOF inheritance issue where if a model gets loaded and an entity that has children located in a different model that hasn't been loaded yet will not be setup correctly. Specifically when those child entities are loaded they will not have their parentEntity relationship set correctly.
