Known Subclasses:

Abstract base class for descriptors Descriptors are to map class instance variables to predicates optional cacheName is where to store items range_type is the rdf:type of the range of this predicate

Instance Methods

[hide private]

__init__(self, pred, cacheName=None, range_type=None)
x.__init__(...) initializes x; see x.__class__.__doc__ for signature

source code

__delete__(self, obj)
deletes or removes from the database triples with: obj.resUri as subject and self.pred as predicate if the object of that triple is a Literal that stop if the object of that triple is a BNode then cascade the delete if that BNode has no further references to it i.e.

source code

Inherited from object: __delattr__, __getattribute__, __hash__, __new__, __reduce__, __reduce_ex__, __repr__, __setattr__, __str__

delete(self, obj)

source code

deletes or removes from the database triples with: obj.resUri as subject and self.pred as predicate if the object of that triple is a Literal that stop if the object of that triple is a BNode then cascade the delete if that BNode has no further references to it i.e. it is not the object in any other triples.
