This is strange:
/**
* Shortcut to return a new ERXKeyFilter(AttributesAndToOneRelationships)
* @return a new ERXKeyFilter(AttributesAndToOneRelationships)
*/
public static ERXKeyFilter filterWithAttributesAndToOneRelationships() {
return new
ERXKeyFilter(ERXKeyFilter.Base.AttributesAndToOneRelationships);
}
/**
* Sets the base rule to AttribtuesAndToOneRelationships.
*/
public void includeAttributesAndToOneRelationships() {
setBase(ERXKeyFilter.Base.AttributesAndToOneRelationships);
}
The first method is the static method and second is instance and the instance
method sets the base after creating the instance.
