Load Drools Guided Decision Table to Java List/Map

Question

Hi I was wondering if there is a way to load all the content of the guided decision table to java collection (list/map)? I achieved this by making each rule(row) calling a java method where I add this to a hashmap but performance-wise is really bad I was wondering if there is a better way to do so. Thanks in advance!
