Apart from that the SDK is fully functional. I'd appreciate any ideas! 2014-02-25 18:03:08.475 otest[3786:303] Unknown Device Type.

Value , value : String ) = { val sqlOperator = operator . toSql [...] So, ConditionOperator

A switch statement would be very long, so I was wondering if there is a simpler way to do this? EDIT: Thanks for all of your replies. I realized that there was a much simpler way to do it for my particular case. The strings always contained the charater 'S' followed by some number so i just did int i = atoi(myStr.c_str() + 1); and then did a switch on i. 回答1: A std::map (or unordered_map ) could do it easily. Populating the map would be just as tedious

The regular enum doesn't have the same values as the enumeration class does. I would therefore like to map using the Name if possible: Enum: public enum ProductType { ProductType1, ProductType2 } Enumeration Class: public class ProductType : Enumeration { public static ProductType ProductType1 = new ProductType(8, "Product Type 1"); public static ProductType

See the code below to understand what I am asking public enum Stuff { A = 1, B = 2, C = 3 } var resultSub = Stuff.A - Stuff.B; // Compiles var resultAdd = Stuff.A + Stuff.B; // Does not compile var resultAdd2 = (int)Stuff.A + Stuff.B; // Compiles note: For both addition and subtraction it does not matter whether result is out of range (of the enum) or not in all three examples above. 回答1: Good question - I was surprised that the first and third lines worked. However, they

I have used underscores as this enum is used in logging and i don't want to incur the overhead of reflection by using custom attribute.We use very heavy logging. Now requirement is to change "LoginFailed_InvalidAttempt1" to "LoginFailed Attempt1". If i change this enum, i will have to change its value across application. I can replace underscore by a space inside logging SP. Is there any way by which i can change this without affecting whole application.Please suggest. public enum ActionType { None, Created

Id Name Sex and sex column have type of enum('Male','Female','Unspecified') How can i list enum values in a dropdown and make current stored value as selected 回答1: Check this link...its pretty awesome..the script is reusable for any enum column: http://jadendreamer.wordpress.com/2011/03/16/php-tutorial-put-mysql-enum-values-into-drop-down-select-box/ 回答2: The fact that it is an enum field doesn't matter much when creating the select (dropdown) fields. Enum fields behave the same

For example, if I have an Enum as follows: public enum InputFlags{ ONE (0000001), TWO (0000002), THREE (00000004); public final int value; InputFlags(int value){ this.value = value; } } I can then do the following: for (InputFlags ifg : InputFlags.values()){ // Do something with ifg } However if I try to do the above in a generic method whose return parameter is bounded, I cannot access the values() method: public static <T extends Enum> T getFlags(int f

Wouldn't it have been better that they were added to Enum class itself? What I mean is, if I have some enum such as enum FooEnum {ONE, TWO} javac adds values() and valueOf(String) to FooEnum when compiling it. I find it a bit odd. What is the reason behind this? Is it only to ensure type safety of the returned value/values or is there anything else? And if it's for type safety alone, wouldn't Generics have helped? 回答1: They're static methods - how could

In the "KeyDown" eventhandler, if the "e.KeyValue" is a number, I want to treat it as a number and store it as an int. So, if I hit "8" on the number pad, I don't want "Numpad8" I want the int value 8 that I can add or subtract or whatever. So, how do I convert from the KeyValue to an int? 回答1: I'd go with this solution: int value = -1; if (e.KeyValue >= ((int) Keys.NumPad0) && e.KeyValue <= ((int) Keys.NumPad9)) { // numpad
