Examples of org.drools.core.reteoo.AlphaNode

org.drools.core.reteoo.AlphaNode
AlphaNodes are nodes in the Rete network used to apply FieldConstraint<.code>s on asserted fact objects where the FieldConstraints have no dependencies on any other of the facts in the current Rule. @see AlphaNodeFieldConstraint
