find string within list of strings-CodePudding

validValueType.ValueTypeGroup

["\"is_enabled\": false", "\"value\":\"OUT\""]
    
failedRecord.record
{"email":"[email protected]","source":"web","value":"OUT","reate_date":"2022-09-29T03:42:09.976-05:00","is_undeliverable":false}
    
        fun publishAlert(failedRecord: Record<String>) {
            if (validValueType.ValueTypeGroup.contains(failedRecord.record)) {
             // do stuff
    
            } else {
                // no match do other stuff
            }
        }

In the list above there are two strings I want to check for when this function receives a record.

The failedRecord.record string does contain what I want "value":"OUT" and it's also within the list above. So why is contains not working here? it keeps bouncing out to the else statement.

CodePudding user response：

You can use any() in the list and pass a predicate:
{x -> searchString.contains(x)}

The searchString.contains() will search x as a substring inside searchString for each x representing the elements in the list

var list = listOf("\"is_enabled\": false", "\"value\":\"OUT\"")
println(list)
println(list::class.qualifiedName)
println() // empty newline
    
var searchString = "{\"email\":\"[email protected]\",\"source\":\"web\",\"value\":\"OUT\",\"create_date\":\"2022-09-29T03:42:09.976-05:00\",\"is_undeliverable\":false}";
println(searchString)
println(searchString::class.qualifiedName)
println() // empty newline
    
println(list.any{x -> searchString.contains(x)});

Output

["is_enabled": false, "value":"OUT"]
java.util.Arrays.ArrayList

{"email":"[email protected]","source":"web","value":"OUT","create_date":"2022-09-29T03:42:09.976-05:00","is_undeliverable":false}
