-# Generating C++ Binder Interfaces with `aidl-cpp`
-
-## Background
-
-“aidl” refers to several related but distinct concepts:
-
- - the AIDL interface [definition language](http://developer.android.com/guide/components/aidl.html)
- - .aidl files (which contain AIDL)
- - the aidl generator which transforms AIDL into client/server IPC interfaces
-
-The _aidl generator_ is a command line tool that generates client and server
-stubs for Binder interfaces from a specification in a file with the .aidl
-extension.  For Java interfaces, the executable is called `aidl` while for C++
-the binary is called `aidl-cpp`.  In this document, we’ll use AIDL to describe
-the language of .aidl files and _aidl generator_ to refer to the code generation
-tool that takes an .aidl file, parses the AIDL, and outputs code.
-
-Previously, the _aidl generator_ only generated Java interface/stub/proxy
-objects.  C++ Binder interfaces were handcrafted with various degrees of
-compatibility with the Java equivalents.  The Brillo project added support for
-generating C++ with the _aidl generator_.  This generated C++ is cross-language
-compatible (e.g. Java clients are tested to interoperate with native services).
-
-## Overview
-
-This document describes how C++ generation works with attention to:
-
- - build interface
- - cross-language type mapping
- - implementing a generated interface
- - C++ parcelables
- - cross-language error reporting
- - cross-language null reference handling
-
-## Detailed Design
-
-### Build Interface
-
-Write AIDL in .aidl files and add them to `LOCAL_SRC_FILES` in your Android.mk.
-If your build target is a binary (e.g. you include `$(BUILD_SHARED_LIBRARY)`),
-then the generated code will be C++, not Java.
-
-AIDL definitions should be hosted from the same repository as the
-implementation.  Any system that needs the definition will also need the
-implementation (for both parcelables and interface).  If there are multiple
-implementations (i.e. one in Java and one in C++), keep the definition with the
-native implementation.  Android
-[now has systems](https://developers.google.com/brillo/?hl=en) that run the
-native components of the system without the Java.
-
-If you use an import statement in your AIDL, even from the same package, you
-need to add a path to `LOCAL_AIDL_INCLUDES`.  This path should be relative to
-the root of the Android tree.  For instance, a file IFoo.aidl defining
-com.example.IFoo might sit in a folder hierarchy
-something/something-else/com/example/IFoo.aidl.  Then we would write:
-
-```
-LOCAL_AIDL_INCLUDES := something/something-else
-```
-
-Generated C++ ends up in nested namespaces corresponding to the interface’s
-package.  The generated header also corresponds to the interface package.  So
-com.example.IFoo becomes ::com::example::IFoo in header “com/example/IFoo.h”.
-
-Similar to how Java works, the suffix of the path to a .aidl file must match
-the package.  So if IFoo.aidl declares itself to be in package com.example, the
-folder structure (as given to `LOCAL_SRC_FILES`) must look like:
-`some/prefix/com/example/IFoo.aidl`.
-
-To generate code from .aidl files from another build target (e.g. another
-binary or java), just add a relative path to the .aidl files to
-`LOCAL_SRC_FILES`.  Remember that importing AIDL works the same, even for code
-in other directory hierarchies: add the include root path relative to the
-checkout root to `LOCAL_AIDL_INCLUDES`.
-
-### Type Mapping
-
-The following table summarizes the equivalent C++ types for common Java types
-and whether those types may be used as in/out/inout parameters in AIDL
-interfaces.
-

-| android.os.Parcelable | android::Parcelable | inout |                                                       |

-
-Note that annotations may be placed at the interface level, as well as on a
-type by type basis.  Interface level annotations will be applied
-opportunistically and be overridden by per type annotations.  For instance, an
-interface marked @nullable will still not allow null int parameters.
-
-### Implementing a generated interface
-
-Given an interface declaration like:
-
-```
-package foo;
-
-import bar.IAnotherInterface;
-
-interface IFoo {
-  IAnotherInterface DoSomething(int count, out List<String> output);
-}
-```
-
-`aidl-cpp` will generate a C++ interface:
-
-```
-namespace foo {
-
-// Some headers have been omitted for clarity.
-#include <android/String16.h>
-#include <cstdint>
-#include <vector>
-#include <bar/IAnotherInterface.h>
-
-// Some class members have been omitted for clarity.
-class IFoo : public android::IInterface {
- public:
-  virtual android::binder::Status DoSomething(
-      int32_t count,
-      std::vector<android::String16>* output,
-      android::sp<bar::IAnotherInterface>* returned_value) = 0;
-};
-```
-
-Note that `aidl-cpp` will import headers for types used in the interface.  For
-imported types (e.g. parcelables and interfaces), it will import a header
-corresponding to the package/class name of the import.  For instance,
-`import bar.IAnotherInterface` causes aidl-cpp to generate
-`#include <bar/IAnotherInterface.h>`.
-
-When writing a service that implements this interface, write:
-
-```
-#include "foo/BnFoo.h"
-
-namespace unrelated_namespace {
-
-class MyFoo : public foo::BnFoo {
- public:
-  android::binder::Status DoSomething(
-      int32_t count,
-      std::vector<android::String16>* output,
-      android::sp<bar::IAnotherInterface>* returned_value) override {
-    for (int32_t i = 0; i < count; ++i) {
-      output->push_back(String16("..."));
-    }
-    *returned_value = new InstanceOfAnotherInterface;
-    return Status::ok();
-  }
-};  // class MyFoo
-
-}  // namespace unrelated_namespace
-```
-
-Note that the output values, `output` and `returned_value` are passed by
-pointer, and that this pointer is always valid.
-
-#### Dependencies
-
-The generated C++ code will use symbols from libbinder as well as libutils.
-AIDL files using the FileDescriptor type will also explicitly require
-libnativehelper, although this is likely a transitive dependency of the other
-two, and should be included automatically within the Android build tree
-regardless.
-
-### C++ Parcelables
-
-In Java, a parcelable should extend android.os.Parcelable and provide a static
-final CREATOR field that acts as a factory for new instances/arrays of
-instances of the parcelable.  In addition, in order to be used as an out
-parameter, a parcelable class must define a readFromParcel method.
-
-In C++, parcelables must implement android::Parcelable from binder/Parcelable.h
-in libbinder.  Parcelables must define a constructor that takes no arguments.
-In order to be used in arrays, a parcelable must implement a copy or move
-constructor (called implicitly in vector).
-
-The C++ generator needs to know what header defines the C++ parcelable.  It
-learns this from the `cpp_header` directive shown below.  The generator takes
-this string and uses it as the literal include statement in generated code.
-The idea here is that you generate your code once, link it into a library along
-with parcelable implementations, and export appropriate header paths.  This
-header include must make sense in the context of the Android.mk that compiles
-this generated code.
-
-```
-// ExampleParcelable.aidl
-package com.example.android;
-
-// Native types must be aliased at their declaration in the appropriate .aidl
-// file.  This allows multiple interfaces to use a parcelable and its C++
-// equivalent without duplicating the mapping between the C++ and Java types.
-// Generator will assume bar/foo.h declares class
-// com::example::android::ExampleParcelable
-parcelable ExampleParcelable cpp_header "bar/foo.h";
-```
-
-### Null Reference Handling
-
-The aidl generator for both C++ and Java languages has been expanded to
-understand nullable annotations.
-
-Given an interface definition like:
-
-```
-interface IExample {
-  void ReadStrings(String neverNull, in @nullable String maybeNull);
-};
-```
-
-the generated C++ header code looks like:
-
-```
-class IExample {
-  android::binder::Status ReadStrings(
-      const android::String16& in_neverNull,
-      const std::unique_ptr<android::String16>& in_maybeNull);
-};
-```
-
-Note that by default, the generated C++ passes a const reference to the value
-of a parameter and rejects null references with a NullPointerException sent
-back the caller.  Parameters marked with @nullable are passed by pointer,
-allowing native services to explicitly control whether they allow method
-overloading via null parameters.  Java stubs and proxies currently do nothing
-with the @nullable annotation.
-
-Consider an AIDL type `in @nullable List<String> bar`.  This type
-indicates that the remote caller may pass in a list of strings, and that both
-the list and any string in the list may be null.  This type will map to a C++
-type `unique_ptr<vector<unique_ptr<String16>>>* bar`.  In this case:
-
-  - `bar` is never null
-  - `*bar` might be null
-  - `(*bar)->empty()` could be true
-  - `(**bar)[0]` could be null (and so on)
-
-### Exception Reporting
-
-C++ methods generated by the aidl generator return `android::binder::Status`
-objects, rather than `android::status_t`.  This Status object allows generated
-C++ code to send and receive exceptions (an exception type and a String16 error
-message) since we do not use real exceptions in C++.  More background on Status
-objects can be found here.
-
-For legacy support and migration ease, the Status object includes a mechanism
-to report a `android::status_t`.  However, that return code is interpreted by a
-different code path and does not include a helpful String message.
-
-For situations where your native service needs to throw an error code specific
-to the service, use `Status::fromServiceSpecificError()`.  This kind of
-exception comes with a helpful message and an integer error code.  Make your
-error codes consistent across services by using interface constants (see
-below).
