See Also:   AlphaNodeFieldConstraint author:    Mark Proctor author:    Bob McWhirter Constructor Summary public   AlphaNode(int id, AlphaNodeFieldConstraint constraint, ObjectSource objectSource, boolean hasMemory, int alphaNodeHashingThreshold)      Construct an AlphaNode with a unique id using the provided FieldConstraint and the given ObjectSource.

Set the boolean flag to true if the node is supposed to have local memory, or false otherwise. Memory is optional for AlphaNodes and is only of benefic when adding additional Rules at runtime. Parameters:   id - Node's ID Parameters:   constraint - Node's constraints Parameters:   objectSource - Node's object source Parameters:   hasMemory - true if node shall be configured with local memory. False otherwise.
