Re: [rules-users] @key declarations for a type - What's under the hood?

Drools bytecode generates these beans without generating java source code (if you are using the declare, not the data modeller). Having said that, it is very simple: declare Here location: String @key end Generates a java class roughly equivalent to: public class Here implements Serializable { private String location; public Here() {} public Here( String location ) { this.location = location; } public String getLocation() { return location; } public void setLocation(String location) { this.location = location; } // generates a toString() // generates a hashCode()/equals() method that use the location's hashcode()/equals() } I did this from memory, but it is pretty much all it does. Nothing complex there, just a javabean really. The difference to not using @key is that the hashCode()/equals() methods would not take "location" in consideration, and in this case, since there are no other attributes, would then rely on system identity.
