java - Loading and updating rules from a database in Drools 6 -


how 1 go loading rules database table @ startup , updating them same table in drools 6.2.0? i've found example using drools 5 convert scala java looks api has changed pretty drastically... don't see rulebasefactory class, example.

any sample or documentation appreciated.

i'm not sure org.dools.rulebasefactory taken. below how done in drools 5.3 (and possibly earlier) 5.6:

knowledgebuilder kbuilder = knowledgebuilderfactory.newknowledgebuilder(); kbuilder.add( ..., resourcetype.drl); if( kbuilder.haserrors() ){     system.err.println( "### compilation errors ###" );     knowledgebuildererrors errors = kbuilder.geterrors();     for( knowledgebuildererror err: errors ){         system.err.println( err.tostring() );     }     throw new illegalstateexception( "compile errors" ); } knowledgebase kbase = kbuilder.newknowledgebase(); statelessknowledgesession ksession = kbase.newstatelessknowledgesession();

the ellipsis indicates place inserting data holding rule text. check api suitable types; java.lang.string should acceptable.

this way use 6.2:

kieservices kieservices = kieservices.factory.get(); kiefilesystem kfs = kieservices.newkiefilesystem(); kfs.write( "src/main/resources/simple.drl", ... ); kiebuilder kiebuilder = kieservices.newkiebuilder( kfs ).buildall(); results results = kiebuilder.getresults(); if( results.hasmessages( message.level.error ) ){     system.out.println( results.getmessages() );     throw new illegalstateexception( "### errors ###" ); } kiecontainer kiecontainer =     kieservices.newkiecontainer( kieservices.getrepository().getdefaultreleaseid() ); kiebase kiebase = kiecontainer.getkiebase(); kiesession = kiecontainer.newkiesession();

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
