QUESTION
I have Enumutils like below:
...ANSWER
Answered 2022-Jan-11 at 17:16As directed by Joachim Sauer in comment:
EnumUtil.fromValue() simply assumes that there's always exactly one identifiying string for each enum value. That's not true for your second sample. So either don't use EnumUtil.fromValue() or extend it to also support multiple values (probably by having a second interface that can return an array or collection of potentital identifiers) –
Accordingly, EnumUtils Removed from enum and created methods inside enums only.
QUESTION
We have multiple enum types that have some public static EnumType valueOfText(String text)
, for the purpose of mapping the contents of a data file cell to enum.
I'm trying to write a generic enum util that takes a comma-separated string and return multiple enum values. For example, we have the following enum:

instead of just using a type parameter.

In the Get request method given below I want to check if more than 1 parameters are given in the request. It is only allowed to use one of the three possible parameters, when more than 1 is given I will throw an error.
...ANSWER
Answered 2021-Jan-09 at 19:56How can I check if more than 1 RequestParam is given in the request?
Why not with a fast fail check by relying on the count of non null parameters ?

Hi All i am trying to generate the word document with two different tables included in it, for this purpose i have two similar methods where i am passing word document reference and data object and table to the similar methods..
Now i am looking to make single method in generic way so that in different places i can use single method by passing parameters to it
Method 1 :
...ANSWER
Answered 2020-Jun-09 at 12:08Before we can create a single function that handles both types, achieving the highly laudable goal of removing gratuitous duplication, we should clean the code up to make it easier to see which parts, if any, are different between the two nearly identical methods. And there is a lot to clean up, even if we only had one function.
In short, your functions are too long, having too much much code in one place, and in fact too much code altogether. In the following, the original code has been broken down into multiple functions with specific purposes and refactored to remove DIY nonsense in favor of the standard library functions and the removal of pointless code.

QUESTION
SOLUTION IS IN EDIT OF THE ACCEPTED ANSWER
I have a view in which has two Pickers, I need to have it so that when the SelectedItem
property in one Picker changes, the list of Items in the second Picker
(ItemSource) changes as well.
Currently I have a bound the SelectedItem
and SelectedIndex
properties of both pickers to properties in my ViewModel
. In the setter(s) for both of them, I perform the logic needed to change the list of Items in the second picker. The list of Items in the second picker changes successfully, but when I set the SelectedIndex
(to make it select an Item by default), this fails if the index which I am setting it to is the same as the index which it was on in the previous list. It just shows the Title
of the Picker instead, this issue seems to be related to this bug.
My Code:
- Both Pickers are bound to an Observable collection of strings FYI
FrameType
andDirectionType
areEnums
- I initially used only the
SelectedItem
property
Relevant XAML
...ANSWER
Answered 2020-Jan-23 at 06:55I don't really see why you are using both SelectedItem
and SelectedIndex
, but I think what you are trying to achieve can be achieved easier.
First of all, I don't think you need ObservableCollection
types at all in your example, since you are setting the directions anyway and not modifying the collection. More importantly, fiddling around with the indices is completely unnecessary, as far as I can tell. You are using strings anyway and even though String
is not a value type, but a reference type, you cannot practically distinguish two String
instances that have the same content, hence assinging the respective values to SelectedDirection
and SelectedFrame
is sufficient.
The following checks seem redundant to me
