Functions with different signatures, but the same body


Functions with different signatures, but the same body

To fix this issue You can reduce them into two constructors if you reorder the arguments and use varargs:
code :
public ShortcutButton(String text, ActionListener actionListener, KeyStroke... keyStrokes) {
    super(text);
    addActionListener(actionListener);
    addShortcuts(keyStrokes);
}
public ShortcutButton(String text, ActionListener actionListener, String... keyStrokes) {
    super(text);
    addActionListener(actionListener);
    addShortcuts(keyStrokes);
}
public ShortcutButton(String text, ActionListener actionListener, KeyStroke... keyStrokes) {
    super(text);
    addActionListener(actionListener);
    addShortcuts(keyStrokes);
}
public ShortcutButton(String text, ActionListener actionListener, String... keyStrokes) {
    this(text,actionListener,getShortCuts(keyStrokes));
}

Why do multiple-inherited functions with same name but different signatures not get treated as overloaded functions?

This might help you The following snippet produces an "ambigious call to foo" error during compilation, and I'd like to know if there is any way around this problem without fully qualifying the call to foo: , Member lookup rules are defined in Section 10.2/2
code :
class A {
public:
  int f(int);

};
class B {
public:
   int f();

};
class C : public A, public B {};
int main()
{
     C c;
     c.f(); // ambiguous
}
class C : public A, public B {
     using A::f;
     using B::f;

};

int main()
{
     C c;
     c.f(); // fine
}

help you fix your problem I have a function like so: , One approach is to use a (polymorphic) helper function, e.g.:
code :
helper ctor xs rest = ctor [ head xs ] : rest

test :: [Block] -> [Block]
test ((Para xs):rest)  = helper Para xs rest
test ((Plain xs):rest) = helper Plain xs rest
test bs                = bs

this one helps. DLLs do not store the signatures of the functions they export. Other answers have mentioned C++, and when a C++ function is exported as C++, then the name will indeed be mangled. Demangle it with the right compiler's mangling scheme, and you'll have the signature. But most DLLs do not export C++ functions using their C++ names. Instead, the functions a DLL chooses to export are exported using C-style names, so even if the DLL was written in C++, the exported functions still won't have any signature information.
You don't have the header? Most vendors include that sort of thing in their SDKs. If you didn't get one, then complain to the vendor. If you weren't supposed to get one, then maybe you're going about your task the wrong way; are you sure you're supposed to use that DLL directly?

I hope this helps . We decided not to do this as users might have configured multiple signatures. So, let users add signature in the end.

seems to work fine Greg is right. You need to use the raw body request to check the ingredients of the message. The following code employs the body-parser library to extract the raw body.
code :
var bodyParser = require("body-parser");

app.use(bodyParser.json({verify:function(req,res,buf){req.rawBody=buf}}))
app.post('/webhooks', function(req, res) {

    const retrievedSignature = req.get("X-header-Integrity")
    //send this body string for validation with secret
    const bodyString = Buffer.from(req.rawBody, 'utf8')

    let check = integrityCheck(retrievedSignature, bodyString, "secret")

});
