Example 1 with PrototypeVariable

use of org.drools.model.PrototypeVariable in project drools by kiegroup.

the class FactTemplateTest method testBeta.

@Test
public void testBeta() {
    Result result = new Result();
    Prototype personFact = prototype("org.drools", "Person", field("name", Integer.class), field("age", String.class));
    PrototypeVariable markV = declarationOf(personFact);
