[rules-users] What is insertLogical in drools?

[Wolfgang Laun]

The "Expert" manual says:

insertLogical(new *Something*()); is similar to insert, but the object will
be automatically retracted when there are no more facts to support the truth
of the currently firing rule.

In other words, as soon as the condition of that rule is not true any more,
the Engine retracts the logically inserted fact. This is commonly referred
to as "truth mainenance".
