build

public void build(BuildContext context,
                  BuildUtils utils,
                  RuleConditionElement rce)

Description copied from interface: ReteooComponentBuilder

Builds and attach if needed the given RuleConditionalElement

Specified by:: build in interface ReteooComponentBuilder

Parameters:: context - current build context

requiresLeftActivation

public boolean requiresLeftActivation(BuildUtils utils,
                                      RuleConditionElement rce)

Description copied from interface: ReteooComponentBuilder

A boolean function that indicates if the builder requires a previous left (tuple) activation in order to corretly build the given component. In other words, if it returns true and no previous TupleSource is already created, an InitialFact pattern must be added with appropriate left input adapter for the network to be correctly built. For instance, NOT / EXISTS / ACCUMULATE are examples of builders that must return true for this method, while PATTERN must return false.
