Drools: case insensitive compare?

I need to compare two fields in a case insensitive way. I have a rule something like this:

foo : ObjectTypeA()
bar : ObjectTypeB( name == foo.name )

And that works for strings that are the same case. What I need is something like this, but it doesn't seem to work:

foo : ObjectTypeA()
bar : ObjectTypeB( name.equalsIgnoreCase( foo.name ) )

Any suggestions on how to get that to work? Googling hits on suggestions to use "matches", but the matches operator only seems to work against a hard coded pattern.

Solution

  • Use eval. equalsIgnoreCase method also had a typo in your example code.

    bar : ObjectTypeB(  eval( name.equalsIgnoreCase( foo.name ) ) )

    If you want to use something like: 

    ObjectType( name equalsIgnoreCase foo.name )

    You can take a look at Drools custom operators. Example: http://members.inode.at/w.laun/drools/CustomOperatorHowTo.html
