MayChange
Description
Tells if a node's value in the evidence collection may be changed. This method is only interesting when the inference engine does time-series inference. Currently, when anEngine.Type= ine_HmmCopyBack.
Syntax
someEvidence.MayChange(indexNode)
Parameter
Description
someEvidence
an Evidence object.
indexNode
An integer, or a string, or a Node object specifying a Node object in the ModelNodes collection.
Return Value
A Boolean that is true only if the evidence setting for the node can be changed.
Remarks
For the default inference engine, this will always be true. It will sometimes be false when the inference type is ine_HmmCopyBack.
If you refer to a node by index number be sure to use the node's position in the ModelNodes collection, not its position in the Evidence collection.
