Traverses links from a proposition to a list of propositions.

Parameters:

links - the Links to traverse. If null or an empty array, then the supplied proposition is returned.

proposition - the Proposition from which to start.

forwardDerivations - map of propositions from raw data toward derived propositions.

backwardDerivations - map of propositions from derived propositions toward raw data.

references - a map of unique id to the corresponding proposition for propositions that are referred to by other propositions.

knowledgeSource - the KnowledgeSource.

Returns:

the list of Propositions at the end of the traversals.

Throws:

KnowledgeSourceReadException - if an error occurred reading from the knowledge source.
