Interface AttributePath

All Known Implementing Classes:
AttributePathImpl
public interface AttributePath
An AttriutePath represents a list of attribute names.

AggregateClasses can contain as attribute values further AggregateClasses. To identifiy an attribute, it is necessary to specify all attribute names from the top AggregateClass. This path of attributes can be expressed using the AttributePath.
