scala - Comparing String and Enumeration -


I have a calculation slapped for string in JPA. For more comfortable coding, I define the implicit conversions among them. So I can now define the value val person. = "User" , - person.role is a type of code "user" a string so there is a conversion but when I compare these two If I try, I always feel falsely, because def equals (arg0: any): any to boolean, so no trigger is triggered. has gone. I need some explicit conversion, but to be able to leave my plan, do you think the best practice is the best solution here?

value ("user") code> enumeration type Is wal . And I believe that this does not compare the string name of the implementation value of equal to I think joining a heavy hand to do this is my own census and Is making value so that the name is correct if it is correct.

but uses my code, not with JPA, I always convert the string to MyEnumeration.Value . It's easy with things: 

  Object is expanded to e {val user = value ("user")} skeleton & gt; Val a = E.withName ("user") a: E.Value = User

Note that when using withName , any string You do not get an exception in the calculation that does not match the name.

Then always use the calculator field in your comparison: 

  scala> A == E User res9: Boolean = true

If JPA only gives a string, and there is no way around it. Then I think the best option is to either convert the value to the string, change the string to string or upgrade the string to the value and compare the value of the values, these types will not be used to compare , Unless you implement any type of extension of the equal method, and it is difficult.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
