====== Mixin redirectors ======
===== introduction =====

Redirectors are methods that can replace method invocations, field accesses, object creation, and ''instanceof'' checks. Redirectors are declared by ''@Redirect'' annotations and generally look like this:

<code java [enable_line_numbers=true]>
@Redirect(method = "${signatureOfMethodInWhichToRedirect}",
          at = @At(value = "${injectionPointReference}", target = "${signature}"))
public ReturnType redirectSomeMethod(Arg0Type arg0, Arg1Type arg1) {
    MyClass.doMyComputations();
  
    return computeSomethingElse();
}
</code>

:!: //Redirectors of all kinds work by redirecting the target to your handler method. This causes a hard incompatibility if another mod tries to redirect the same target as this makes it impossible to chain or nest redirects. This makes @WrapOperation and @ModifyExpressionValue from MixinExtras preferable for all use-cases where the developer does not directly intend for an incompatibility. You can find more information about those alternatives on the [[https://github.com/LlamaLad7/MixinExtras/wiki|Official MixinExtras Wiki]].//
