Why does the following program throw an exception? public class MainClass{ public static void main(String[] argv){ callMethod(2); } public static void callMethod(Integer... i){ System.out.println("Wrapper"); } public static void callMethod(int... i){ System.out.println("Primitive"); } } The method cal...
Hi, Is it possible to add default arguments before variable argument in variadic macro? e.g I have the version of macro something like #define MACRO(arg1, ...) func(arg1, ##__VA_ARGS__) I would like to add 2 more default arguments in the macro before variable arguments so that it should not affect previous version. Like: #define MAC...
What does this mean? void message(int x, int y, ...) I can't understand what ... is. Can anybody explain? ...
HI, i have googled and came to know that how to use the variable arguments. but i want to pass my variable arguments to another method. i m getting errors. how to do that ? -(void) aMethod:(NSString *) a, ... { [self anotherMethod:a]; // i m doing this but getting error. how to pass complete vararg to anotherMethod } ...
I am trying to build a command which is similar to LaTeX \cite{}, which accepts a comma-separated list of parameters like this \cite{Wall91, Schwartz93} I would like to pass each item in the comma-separated list which the parameter represents to another command and return the concatenation of the individual results. I imagine it to be ...
I consider refactoring few method signatures that currently take parameter of type List or Set of concrete classes --List[Foo]-- to use repeated parameters instead: Foo*. Update: Following reasoning is flawed, move along... This would allow me to use the same method name and overload it based on the parameter type. This was not po...
I have a varargs contructor like this : public class Sentence { public String[] str; public Sentence(Object... text){ StringBuilder sb = new StringBuilder(); for (Object o : text) { sb.append(o.toString()) .append(" "); } System.out.println(sb.toString()); } } Con...
I know that __stdcall functions can't have ellipses, but I want to be sure there are no platforms that support the stdarg.h functions for calling conventions other than __cdecl or __stdcall. ...
There seems to be a bug in the Java varargs implementation. Java can't distinguish the appropriate type when a method is overloaded with different types of vararg parameters. It gives me an error The method ... is ambiguous for the type ... Consider the following code: public class Test { public static void main(String[] args) thr...
Simple question, how make this code working ? public class T { public static void main(String[] args) throws Exception { new T().m(); } public // as mentioned by Bozho void foo(String... s) { System.err.println(s[0]); } void m() throws Exception { String[] a = new String[]{"hello", "kit...
What is wrong is the following method? def someMethod(funcs: => Option[String]*) = { ... } ...
I've been trying to get to mock a method with vararg parameters using Mockito: interface A { B b(int x, int y, C... c); } A a = mock(A.class); B b = mock(B.class); when(a.b(anyInt(), anyInt(), any(C[].class))).thenReturn(b); assertEquals(b, a.b(1, 2)); This doesn't work, however if I do this instead: when(a.b(anyInt(), anyInt()))...
If I define some macro: #define foo(args...) ({/*do something*/}) Is there some way to actually loop through args rather than pass it along to another function? Something like #define foo(args...) \ { \ for (int i = 0; i < sizeof(args); ++i) { \ /*do something with args[i]*/ \ } \ ...
How to pass by-name repeated parameters in Scala? The following code fails to work: scala> def foo(s: (=> String)*) = { <console>:1: error: no by-name parameter type allowed here def foo(s: (=> String)*) = { ^ Is there any other way I could pass a variable number of by name parameters to the method? ...
Hello I have a function -(id) func: params1, ... NS_REQUIRES_NIL_TERMINATION and2: params2, ... NS_REQUIRES_NIL_TERMINATION; Compiler says: error: expected `;' before 'and2' Is there any way to make function with 2 argument lists? ...
It seems that in Lua, I can either pass vararg on to another function, or take a peek at them through arg, but not both. Here's an example: function a(marker, ...) print(marker) print(#arg, arg[1],arg[2]) end function b(marker, ...) print(marker) destination("--2--", ...) end function c(marker, ...) print(marker) print(#ar...
Suppose you have a Java method void foobar(int id, String ... args) and want to pass both String arrays and Strings into the method. Like this String arr1[]={"adas", "adasda"}; String arr2[]={"adas", "adasda"}; foobar(0, "adsa", "asdas"); foobar(1, arr1); foobar(2, arr1, arr2); foobar(3, arr1, "asdas", arr2); In Python there is "*"...
Here is something I can do in java, take the results of a repeated parameter and pass it to another method: public void foo(String ... args){bar(args);} public void bar(String ... args){System.out.println("count="+args.length);} In scala it would look like this: def foo(args:String*) = bar(args) def bar(args:String*) = println("count...
I am trying to improve SQLite error handling in an existing C++ program. I have a custom type SQLiteException, and I want to write a macro to print the line number, file name, and error messages from SQL. I have the following functions defined: LogMessage(LPCTSTR message); // Does the real work. Appends a timestamp to the message and...
If the function was defined with a prototype which explicitly stated the types of the parameters, eg. void somefunc(int arg1, float arg2); but is implemented as void somefunc(int arg1, ...) { ... } is it possible to use va_arg to retrieve a float? It's normally prevented from doing this because varargs functions have implicit typ...
