jboss - Drools rules categorization -

-

i looking way categorize rules in drl files , determine category/ categories of rules fired.

i see drools guvnor documentation has categorization http://docs.jboss.org/drools/release/5.2.0.final/drools-guvnor-docs/html/ch03.html#d0e228. however, unclear me if metadata maintained guvnor or if part of drl file/ rules execution. have not been able find sample drl file category mentioned in it. and, way determine category/ categories of rules got fired.

i aware of activation-group doesn't quite fit need since once rule in activation-group fires other rules in group not evaluated.

thanks

the best way classify rules via metadata. metadata entry added rule:

rule metademo   @meta2( 123 )   @meta3( foo  )   @meta4( "foo" ) when...then...end

you access metadata via rule, obtained package or event:

for( rule rule: kpackage.getrules() ){     map<string,object> key2meta = rule.getmetadata();     for( map.entry<string,object> entry: key2meta.entryset() ){         system.out.print( "   @" + entry.getkey() + "( " );         object value = entry.getvalue();         system.out.print( "[" + value.getclass().getsimplename() + "] "                           + value.tostring() );         system.out.println( " ) " );     } }

output:

@meta2( [integer] 123 )  @meta4( [string] foo )  @meta3( [string] foo )

there plan permit maps value might use

@meta7( foo = "foo", bar = "bar" )

this didn't work in 5.5, , never tried again.
