EntitypathExp and returns an Iterator of path
components that contains a sequence of Attributes and Relationships. Note that if
path is invalid and can not be resolved from this entity, this method will still
return an Iterator, but an attempt to read the first invalid path component will
result in ExpressionException.resolvePathComponents in class EntityExpressionExceptionpublic void setPrimaryKeyGenerator(DbKeyGenerator primaryKeyGenerator)
