Hi,<br><br>As of my current understanding of Drools, an instance of a bean class is acted upon when it is asserted onto a DRL file (using: assertObject). However, the limitation in such a scenario is that the bean class cannot accept a dynamic data-set. If say, my input parameters are varying in number then I can't possibly capture the data in a properly defined bean class. On the other hand, I can capture the data in a data structure like HashMap.
<br>But my problem arises when I try to use the value for a HashMap key in the DRL file, since in the "when" part I can only use "getter" methods which accept no parameters. I did try to circumvent this problem by setting a
<span style="font-style: italic;">key </span>value in a particular getter method before asserting the bean object and then retrieving the value through a <span style="font-style: italic;">getValue </span>method which would return the value from the HashMap for the key value associated with the current instance of the asserted bean class. But this too leads to another problem; at any given instant I can only associate a single
<span style="font-style: italic;">key </span>value with a bean instance, thus, if I need a rule to have <span style="font-style: italic;"></span>multiple conditions (AND/OR) based on different key-values stored in the HashMap, I can't access them simultaneously.
<br><br>I was wondering, is there a way by which I can access a method, of the asserted Bean class, from the "when" part of a rule, in the DRL file, which can accept a parameter input? If no, is there any part of the source code where I can make some changes to allow this behaviour (pointers to the class names concerned)?
<br><br>Any and all assistance would be hugely appreciated.<br><br>Thanks!<br>Anirvan<br>
