drools Rule (V) Notes A Note on the original type of automatic packing and on Auto-boxing and Primitive Types

Try Drools its original packaging or retention of digital objects, and therefore bind to the primitive int variable is no longer required to manually cancel the packing when used in a code block or expression; 3.0 Drools different, all primitives are automatically packing and unpacking manually. Variable is bound to an object will remain as the wrapper objects; in this case, application of existing rules JDK 1.5 and JDK 5 to handle automatic boxing and unboxing. When evaluating field constraints, where the system will try to cast a value comparable format; so the object primitive wrapper considerable.
