c# How can i use class name in another class string -

-

given 2 following method definitions: 

public int sumclass(int a, int b) {   return + b; }  public int multclass(int a, int b) {   return * b; }

i able call either of methods using name of method string

public int process(string classname, int a, int b) {   // classname="sumclass" or classname="multclass"   return classname(a,b); }

i show reflection approach want. won't because there better approach. why want that? because have different methods addition , multiplication. 1 better way to use enum:

public enum processtype {      multiplication,     addition,     division,     subtraction }  public int process(processtype processtype, int a, int b) {     switch (processtype)     {          case processtype.addition:             return sumclass(a, b);         case processtype.multiplication:             return multclass(a, b);          // ...     } }

so if want sum 2 + 3:

int result = process(processtype.addition, 2, 3);

i wish write custom appender on basis of outputstreamappender . wrote following class package tests; import java.io.ioexception; import java.io.outputstream; import ch.qos.logback.core.outputstreamappender; public class myappender<e> extends outputstreamappender<e> { public myappender() { system.out.println("myappender created"); setoutputstream(new outputstream() { @override public void write(int b) throws ioexception { throw new unsupportedoperationexception(); } }); } } then wrote following runner: package tests; import org.slf4j.loggerfactory; import ch.qos.logback.classic.logger; public class runner { private static final logger log = (logger) loggerfactory.getlogger(runner.class); public static void main(string[] args) { //log.addappender(new myappender<iloggingevent>()); log.info("hello world"); } } finall...

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
