rdkit.VLib.Output module¶
- class rdkit.VLib.Output.OutputNode(dest=None, strFunc=None, **kwargs)¶
Bases:
VLibNode
base class for nodes which dump output
Assumptions:
destination supports a write() method
strFunc, if provided, returns a string representation of the input
inputs (parents) can be stepped through in lockstep
Usage Example:
>>> from rdkit.VLib.Supply import SupplyNode >>> supplier = SupplyNode(contents=[1,2,3]) >>> from io import StringIO >>> sio = StringIO() >>> node = OutputNode(dest=sio,strFunc=lambda x:'%s '%(str(x))) >>> node.AddParent(supplier) >>> node.next() 1 >>> sio.getvalue() '1 ' >>> node.next() 2 >>> sio.getvalue() '1 2 '
- next()¶
part of the iterator interface
raises StopIteration on failure
