Re: [rules-users] Using constant for salience instead of hardcoded values?
You can use:
- a fully qualified public static field, e.g. salience (
(int)java.lang.Math.PI )
- a DRL-defined function, e.g. function int FOO(){ return 10; } ...
salience( FOO() )
- a global, e.g. global Integer foo; ... salience ( foo ). But
initialisation is clumsy and not checked by a compiler.
- any field from any fact.
You can NOT use a static field imported with a start pathname, e.g.,
import function com.acme.*.

Salience can be defined using expressions - so have you tried it?
If referencing a static constant (perhaps in a java class) doesn't work
you could try a global,
if that doesn't work try defining a function call which returns the
desired value, if that doesn't work you could add an extra fact containing
the value, bind the value to the variable and then use that variable for the
salience.
Once you've tried it let us know which ways do/don't work!

Hi all,
Is it possible to use a constant for salience instead of hardcoded value?
It have a sence when you have many rules and only several salience level.
They maybe more descriptive like START, VALIDATION, etc and easier to
maintain in the future. If it not possible right now, then maybe it worth to
request like feature request in the future?

Re: [rules-users] Using constant for salience instead of hardcoded values?
One way to achieve this (with a little extra effort) would be to use a DSL where you define START etc. as keywords with an expansion to salience 100 etc. -W On 4 May 2011 10:09, alebu ale...@gmail.com wrote: Hi all, Is it possible to use a constant for salience instead of hardcoded value?

Salience can be defined using expressions - so have you tried it? If referencing a static constant (perhaps in a java class) doesn't work you could try a global, if that doesn't work try defining a function call which returns the desired value, if that doesn't work you could add an extra fact containing the value, bind the value to the variable and then use that variable for the salience.
