rdkit.VLib.Supply module

class rdkit.VLib.Supply.SupplyNode(contents=None, **kwargs)

Bases: VLibNode

base class for nodes which supply things

Assumptions:

1. no parents

Usage Example:

>>> supplier = SupplyNode(contents=[1,2,3])
>>> supplier.next()
1
>>> supplier.next()
2
>>> supplier.next()
3
>>> supplier.next()
Traceback (most recent call last):
    ...
StopIteration
>>> supplier.reset()
>>> supplier.next()
1
>>> [x for x in supplier]
[1, 2, 3]

AddParent(parent, notify=1)

>>> p1 = VLibNode()
>>> p2 = VLibNode()
>>> c1 = VLibNode()
>>> c1.AddParent(p1)
>>> len(c1.GetParents())
1
>>> len(p1.GetChildren())
1
>>> c1.AddParent(p2,notify=0)
>>> len(c1.GetParents())
2
>>> len(p2.GetChildren())
0
>>> p2.AddChild(c1,notify=0)
>>> len(c1.GetParents())
2
>>> len(p2.GetChildren())
1

next()

part of the iterator interface

raises StopIteration on failure

reset()

resets our iteration state
