Eclipse: Java Enum auto-completion of switch case

Question

Is there a CTRL+space -like way of \"auto-constructing\" a switch case around a given Java Enum in Eclipse? I\'d like a stub with all Enum cases...

Answer 1

I don't know if it's possible to do this as a template, because the template would have to know which enum type you were using. But you could write a little script to print out the statement for you, and then just copy its output into your source file.

public class SwitchWriter {
  public static void printSwitchStatement(String varName, Class E) {
    System.out.format("switch(%s) {\n", varName);
    for (Object o : E.getEnumConstants()) {
      System.out.format("case %s:\n  // TODO: Auto-generated switch statement stub\n  break;\n", o);
    }
    System.out.println("default:\n  // TODO: Auto-generated switch statement stub\n}");
  }
}

Output of SwitchWriter.printSwitchStatement("action", java.awt.Desktop.Action.class):

switch(action) {
case OPEN:
  // TODO: Auto-generated switch statement stub
  break;
case EDIT:
  // TODO: Auto-generated switch statement stub
  break;
case PRINT:
  // TODO: Auto-generated switch statement stub
  break;
case MAIL:
  // TODO: Auto-generated switch statement stub
  break;
case BROWSE:
  // TODO: Auto-generated switch statement stub
  break;
default:
  // TODO: Auto-generated switch statement stub
}
