ClassDescriptionThe AbstractHistoryNode implements the linked-list management for HistoryNodes.This is the most general-purpose implementation of a history node.This is used as a placeholder until the actual underlying result node can be created.This class is a history node that holds and provides values that are already processed based on our query parameters.A historian query results in a series of nodes from which the ultimate data is read.This is the primary type of result node, that processes values and makes them available to be read by the query.
