The generation happens at compile-time, so any penalty incurred for generating proxies must be dealt with every time you compile. Importantly, you may modify this array to dynamically change the arguments that will be passed on to the original implementation if and when you invoke Proceed. Line 6 asynchronously closes the quotation by writing " to the writer. It requires Reflection. If the method's return type is void, then you must still return null since the invocation handler has a non-void return type. The downsides of using Fody are minimal: The latter demonstrates async semantics, so we'll use that for our example. But now let's use a proxy to change the data written to the writer such that the full string written is: This sample will use the Reflection. Emit version because there are fewer dependencies and is thus simper for a first example. The Invocation object passed to your handler Your invocation handler is what is responsible for defining what happens when your methods are intercepted. One uses Reflection. SayHello writer ; Here we're storing off the printer in a separate variable for clarity and creating a proxy around HelloWorldPrinter with an invocation handler responsible for handling the method's interception. We will proxy that class and intercept the method, logging to a StringWriter asynchronously! Sexy proxy



The downsides of using Fody are minimal: This sample will use the Reflection. Installation Install-Package sexy-proxy Getting Started To get started we'll demonstrate a simple example using a virtual method in a base class. WriteAsync "Hello World! If doing so, Proceed will allow you to invoke that behavior. Thus, the arguments to your intercepted method are contained in the Arguments property: Line 5 asynchronously calls the original implementation of SayHello, which writes the string Hello World! Line 6 asynchronously closes the quotation by writing " to the writer. Furthermore, any costs associated with generating a proxy admitedly fairly minimal are incurrred at runtime rather than compile time. It requires Reflection. By "proxy generator" we mean being able to take an existing class or interface and inject an interceptor that can generically handle each method in the source type and choose when and whether to pass the invocation off to the original implementation if any.

Overview At a high-level there are a handful of concepts that you should understand to take full advantage of this library. If the method's return type is void, then you must still return null since the invocation handler has a non-void return type. To start, let's consider the following class: Decorate it with the [Proxy] attribute Implement the interface IProxy Generally speaking, we'd recommend using the Fody implementation since the costs are negligible and the benefits are useful. Line 5 asynchronously calls the original implementation of SayHello, which writes the string Hello World! If doing so, Proceed will allow you to invoke that behavior. Installation Install-Package sexy-proxy Getting Started To get started we'll demonstrate a simple example using a virtual method in a base class. Proxies around unimplemented methods vs. Proceed ; 6 await writer. The generation happens at compile-time, so any penalty incurred for generating proxies must be dealt with every time you compile. Emit -- this is a problem for iOS apps. We create the proxy itself via Proxy. It requires Reflection. It takes no arguments. Furthermore, any costs associated with generating a proxy admitedly fairly minimal are incurrred at runtime rather than compile time. WriteAsync "Hello World! One uses Reflection. For example, you can proxy on any method, regardless of whether it's marked as virtual or private and the declaring type itself can be private or internal, which is not possible with Reflection. And since your invocation handler can also be an async method or lambda this is straightforward. The end result of this is the string John says, "Hello World! Emit and is simple and works out of the box.

For example, you can proxy on any method, regardless of whether it's marked as virtual or private and the declaring type itself can be private or internal, which is not possible with Reflection. Finally, we invoke SayHello as before on line 9. Proxies around unimplemented methods vs. John says, "Hello World! Line 4 asynchronously writes the string John says, " to the writer. Target-based proxies Sometimes you already have an existing instance of your proxy type and you want to modify the behavior via the decorator pattern. In contrast, if the intercepted method is abstract or declared in an interface, then Proceed will do nothing but return the default value for the return type, or null if the return type is void. So, for example, it can very slightly slow down your iterations when leveraging TDD. Importantly, you may modify this array to dynamically change the arguments that will be passed on to the original implementation if and when you invoke Proceed.

SayHello writer ; Here we're storing off the printer in a separate variable for clarity and creating a proxy around HelloWorldPrinter with an invocation handler responsible for handling the method's interception.

Emit version because there are fewer dependencies and is thus simper for a first example. Line 5 asynchronously calls the original implementation of SayHello, which writes the string Hello World! This addresses all the aforementioned issues. Installation Install-Package sexy-proxy Getting Started To get started we'll demonstrate a simple example using a virtual method in a base class.

By "proxy generator" we mean being able to take an existing class or interface and inject an interceptor that can generically handle each method in the source type and choose when and whether to pass the invocation off to the original implementation if any. Proceed ; 6 await writer. But now let's use a proxy to change the data written to the writer such that the full string written is: If any of these concerns are paramount, sexy-proxy provides an alternative generator that uses Fody. The argument passed to your function is an instance of Invocation more details on that later For now, suffice to say that it allows us to invoke the original behavior of the SayHello method at a time of our choosing.

And since your invocation handler can also be an async method or lambda this is straightforward. One uses Reflection. The latter demonstrates async semantics, so we'll use that for our example. As in the example illustrated in Getting Started, you can intercept methods that already have existing behavior. This is because the invocation handler is the same for all the methods you may be intercepting, which could have wildly different arity. Thus, the arguments to your intercepted method are contained in the Arguments property: Line 6 asynchronously closes the quotation by writing " to the writer. John says, "Hello World!

In contrast, if the intercepted method is abstract or declared in an interface, then Proceed will do nothing but return the default value for the return type, or null if the return type is void. The end result of this is the string John says, "Hello World! Let's break this down into smaller pieces: It requires Reflection. It requires that proxy'd methods be virtual or that the proxy type be an interface and that the type be public.

  1. On your proxy'd type you must either: Target-based proxies Sometimes you already have an existing instance of your proxy type and you want to modify the behavior via the decorator pattern.

  2. One uses Reflection. Other times, however, the behavior you want to apply can be generalized such that you'd rather not have to override each method individually. Finally, we invoke SayHello as before on line 9.
