The description property is what you are looking for. This is the property that is accessed when you print a variable containing an object. You can add description to your own classes by adopting the protocol CustomStringConvertible and then implementing the description property. class MyClass: CustomStringConvertible { var val = 17 public var description: String … Read more
If you just want to serialize for debugging purposes, the shorter way is to use String.Join: var asString = string.Join(Environment.NewLine, dictionary); This works because IDictionary<TKey, TValue> implements IEnumerable<KeyValuePair<TKey, TValue>>. Example Console.WriteLine(string.Join(Environment.NewLine, new Dictionary<string, string> { {“key1”, “value1”}, {“key2”, “value2”}, {“key3”, “value3”}, })); /* [key1, value1] [key2, value2] [key3, value3] */
It formats the string as two uppercase hexadecimal characters. In more depth, the argument “X2″ is a “format string” that tells the ToString() method how it should format the string. In this case, “X2” indicates the string should be formatted in Hexadecimal. byte.ToString() without any arguments returns the number in its natural decimal representation, with … Read more
Python has two different ways to convert an object to a string: str() and repr(). Printing an object uses str(); printing a list containing an object uses str() for the list itself, but the implementation of list.__str__() calls repr() for the individual items. So you should also overwrite __repr__(). A simple __repr__ = __str__ at … Read more
Attach a String() string method to any named type and enjoy any custom “ToString” functionality: package main import “fmt” type bin int func (b bin) String() string { return fmt.Sprintf(“%b”, b) } func main() { fmt.Println(bin(42)) } Playground: http://play.golang.org/p/Azql7_pDAA Output 101010
You can override toString in Javascript as well. See example: function Foo() {} // toString override added to prototype of Foo class Foo.prototype.toString = function() { return “[object Foo]”; } var f = new Foo(); console.log(“” + f); // console displays [object Foo] See this discussion on how to determine object type name in JavaScript.
You can try out this code. Since you cannot override valueOf method you have to define a custom method (getEnum in the sample code below) which returns the value that you need and change your client to use this method instead. public enum RandomEnum { StartHere(“Start Here”), StopHere(“Stop Here”); private String value; RandomEnum(String value) { … Read more
What you want is the Arrays.toString(int[]) method: import java.util.Arrays; int[] array = new int[lnr.getLineNumber() + 1]; int i = 0; .. System.out.println(Arrays.toString(array)); There is a static Arrays.toString helper method for every different primitive java type; the one for int[] says this: public static String toString(int[] a) Returns a string representation of the contents of the … Read more
Convert.ToString() handles null, while ToString() doesn’t.
It is the description instance method, declared as: – (NSString *)description Here’s an example implementation (thanks to grahamparks): – (NSString *)description { return [NSString stringWithFormat: @”Photo: Name=%@ Author=%@”, name, author]; }
