I have a hard time thinking about a descriptive title, so sorry for that.
I'm facing an issue here. I have a lot of code files that I have to manipulate. And I have to find some indexes in order to get a substring.
Here is an example:
public BigInteger getGenbestillingerTilbageKvantitet() {
return genbestillingerTilbageKvantitet;
}
I have to be able to locate the starting index of the above example (I have the entire code file, loaded as a string, so the method shown would be a substring of the entire code file). I'm able to get the index of getGenbestillingerTilbageKvantitet(), because I have "GenbestillingerTilbageKvantitet" in an array (along with others):
int index7 = fileContent.indexOf("get" + capitalizedProps[i])
This is how I do it.
Then I would find the end of the method like this:
int index4 = fileContent.indexOf("}", index3) + 1
The issue is that i need the index of "public". But since the type is not nessecarily "BigInteger" it gives me some trouble.
Does anyone know how to get the index from public? If the type were of a custom type, I could do:
String s = "public " + capitalizedProps[i] + "Type get" + capitalizedProps[i]
int index3 = fileContent.indexOf(s)
Which works sometimes :) But not when the type is BigInteger or even String.
If you want to get the index of the public keyword preceding getGenbestillingerTilbageKvantitet method name then you can use String.lastIndexOf(str) of the substring created from the beginning up to index of getGenbestillingerTilbageKvantitet method name. Something like this:
int pubKeyIdx = fileContent.substring(0, index7).lastIndexOf("public")
where index7 variable holds the index of the method name.

I am trying to make my program read and edit text. I was trying to use the Position=find ( String , 0 ) method but I get the error:
The method "find" isn't declared in the current class.
I have tried different classes but I cant find the correct one.
Which would that be?
How may I find the correct class in the future?
Thanks in advance.
The find is in the String class.
From the documentation:
int find ( String what, int from=0 )
Finds the first occurrence of a substring. Returns the starting position of the substring or -1 if not found.
So what happens?
When you do Position = find(String, 0) You are calling find from which ever class your code is inside, not from String.
Furthermore, I only see one String there… Which String do you want to find in which one? You need two. Yes, find only takes one String, but it is an instance method, not a static method. You are meant to call it on the one you want to search, like this:
var position := string_in_which_you_are_looking.find(string_you_are_looking_for, 0)

select from list by index ${locator_var} ${inp_msge_type}
--getting error as expected string, int found
select from list by index ${locator_var} 7
-----not getting any error
${inp_msge_type}----contains 7 from DB query the result is stored in this variable, to avoid hard coding we need to do this
Is there any way to write
Do not add links to screenshots of code, or error messages, and format the code pieces accordingly - use the ` (tick) symbol to surround them.
The rant now behind us, your issue is that the keyword Select From List By Index expects the type of the index argument to be a string.
When you called it
Select From List By Index ${locator_var} 7
, that "7" is actually a string (though it looks like a number), because this is what the framework defaults to on any typed text. And so it works.
When you get the value from the DB, it is of the type that the DB stores it with; and probably the table schema says it is int. So now you pass an int to the keyword - and it fails.
The fix is simple - just cast (convert) the variable to a string type:
${inp_msge_type}= Convert To String ${inp_msge_type}
, and now you can call the keyword as you did before.
I got some function:
private fun selectHometown() = File("data/towns.txt")
.readText()
.split("\n")
.shuffled()
.first()
And if I try to get or print some string with the 2 values obtained from this function, the first value disappears. For example:
println("${selectHometown() ${selectHometown() }")
Will only print one city name, while I expect two. I guess the problem is related to string concatenation in Kotlin. Of course, I can get the desired result in a different way, but I'm wondering why this one doesn't work.
Windows way of terminating a line is to use "\r\n" so use it as delimiter :
private fun selectHometown() = File("data/towns.txt")
.readText()
.split("\r\n")
.shuffled()
.first()
println("${selectHometown()} ${selectHometown()}")
I am attempting to write an algorithm that selects a specific reference standard (vector) as a function of temperature. The temperature values are stored in a structure ( procspectra(i).temperature ). My reference standards are stored in another structure ( standards.interp.zeroed.ClOxxx ) where xxx are numbers such as 200, 210, 220, etc. I have built the rounding construct and paste it below.
for i = 1:length(procspectra);
if mod(-procspectra(i).temperature,10) > mod(procspectra(i).temperature,10);
%if mod(-) > mod(+) round down, else round up
tempvector(i) = procspectra(i).temperature - mod(procspectra(i).temperature,10);
else
tempvector(i) = procspectra(i).temperature + mod(-procspectra(i).temperature,10);
end
clostd = strcat('standards.interp.zeroed.ClO',num2str(tempvector(i)));
end
This construct works well. Now, I have built a string which is identical to the name of the vector I want to invoke, but I'm uncertain how to actually call the vector given that this is encoded as a string. Ideally I want to do something within the for-loop like:
parameters(i).standards.ClOstandard = clostd
where I actually am assigning that parameter structure to be the same as the vector I have saved in the standards structure I have previously generated (and not just a string)
Could anyone help out?
Don't construct clostd like that (containing the full variable name), make it contain only the last field name instead:
clostd = ['ClO' num2str(tempvector(i))];
parameters(i).standards.ClOstandard = standards.interp.zeroed.(clostd);
This is the syntax of accessing a structure's field dynamically, using a string. So the following three are equivalent:
struc.Cl0123
struc.('Cl0123')
fieldn='Cl0123'; struc.(fieldn)
I have a velocity variable, like this:
$cur_record.getFieldValue("SelectRoles", $locale)
that is supposed to be an array. If I print its value, (just by putting $cur_record.getFieldValue("SelectRoles", $locale) in the code) i get:
["Accountant","Cashier"]
now, i want to iterate those 2 values, Accountant and Cashier, but it seems to be a String, not an Array, how can i convert that to an array so I can iterate it?..
I have tried to iterate it, but does not work, like this:
#foreach($bla_role in $cur_record.getFieldValue("SelectRoles", $locale))
$bla_role
#end
Also tried to get the value, as if it were an array, does not work either:
$cur_record.getFieldValue("SelectRoles", $locale).get(0)
I've tried setting it to another variable, like this:
#set($roleval = $cur_record.getFieldValue("SelectRoles", $locale))
$roleval.get(0)
but it does not work, but if i set a string, as the value is printed (the value hard coded), it does work!, like this:
#set($roleval = ["Accountant","Cashier"])
$roleval.get(0)
I dont know if I have to escape something, or I am missing something, can some one help me?
thank you!
You're trying to parse a String array that was previously serialized to String.
The following snippet uses substring, split and replace String methods to parse it.
#set($roleval = '["Accountant","Cashier"]')
#set($rolevalLengthMinusOne = $roleval.length() - 1)
#set($roles = $roleval.substring(1, $rolevalLengthMinusOne).split(","))
#foreach($role in $roles)
<h1>$role.replace('"',"")</h1>
#end
At first I tried to use #evaluate to parse it, but I ended up with these String methods.
