question: public Object eval ( CallStack callstack , Interpreter interpreter ) throws EvalError { try { NameSpace namespace = callstack . top ( ) ; BSHType typeNode = getTypeNode ( ) ; Class type = typeNode . getType ( callstack , interpreter ) ; BSHVariableDeclarator [ ] bvda = getDeclarators ( ) ; for ( int i = 0 ; i < bvda . length ; i ++ ) { BSHVariableDeclarator dec = bvda [ i ] ; Object value = dec . eval ( typeNode , callstack , interpreter ) ; try { namespace . setTypedVariable ( dec . name , type , value , modifiers ) ; } catch ( UtilEvalError e ) { throw e . toEvalError ( this , callstack ) ; } } } catch ( EvalError e ) { e . reThrow ( "Typed variable declaration" ) ; } return Primitive . VOID ; }
target:  evaluate the type and one or more variable declarators, e.g.: int a, b=5, c;
