| requiresLeftActivation | | public boolean requiresLeftActivation(BuildUtils utils, RuleConditionElement rce)(Code) | | 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.
Parameters:
rce - the element to be built true if a tuple source is required, false otherwise. |
