+// Please consider splitting the single license below into multiple licenses,

+// For unused files, consider creating a 'fileGroup' with "//visibility:private"

+ // Generic type read and write methods for Parcel:
+ //
+ // readData(T *value) will read a value from the Parcel.
+ // writeData(const T& value) will write a value to the Parcel.
+ //
+ // Our approach to parceling is based on two overloaded functions
+ // readData() and writeData() that generate parceling code for an
+ // object automatically based on its type. The code from templates are generated at
+ // compile time (if constexpr), and decomposes an object through a call graph matching
+ // recursive descent of the template typename.
+ //
+ // This approach unifies handling of complex objects,
+ // resulting in fewer lines of code, greater consistency,
+ // extensibility to nested types, efficiency (decisions made at compile time),
+ // and better code maintainability and optimization.
+ //
+ // Design decision: Incorporate the read and write code into Parcel rather than
+ // as a non-intrusive serializer that emits a byte stream, as we have
+ // active objects, alignment, legacy code, and historical idiosyncrasies.
+ //
+ // --- Overview
+ //
+ // Parceling is a way of serializing objects into a sequence of bytes for communication
+ // between processes, as part of marshaling data for remote procedure calls.
+ //
+ // The Parcel instance contains objects serialized as bytes, such as the following:
+ //
+ // 1) Ordinary primitive data such as int, float.
+ // 2) Established structured data such as String16, std::string.
+ // 3) Parcelables, which are C++ objects that derive from Parcelable (and thus have a
+ // readFromParcel and writeToParcel method). (Similar for Java)
+ // 4) A std::vector<> of such data.
+ // 5) Nullable objects contained in std::optional, std::unique_ptr, or std::shared_ptr.
+ //
+ // And active objects from the Android ecosystem such as:
+ // 6) File descriptors, base::unique_fd (kernel object handles)
+ // 7) Binder objects, sp<IBinder> (active Android RPC handles)
+ //
+ // Objects from (1) through (5) serialize into the mData buffer.
+ // Active objects (6) and (7) serialize into both mData and mObjects buffers.
+ //
+ // --- Data layout details
+ //
+ // Data is read or written to the parcel by recursively decomposing the type of the parameter
+ // type T through readData() and writeData() methods.
+ //
+ // We focus on writeData() here in our explanation of the data layout.
+ //
+ // 1) Alignment
+ // Implementation detail: Regardless of the parameter type, writeData() calls are designed
+ // to finish at a multiple of 4 bytes, the default alignment of the Parcel.
+ //
+ // Writes of single uint8_t, int8_t, enums based on types of size 1, char16_t, etc
+ // will result in 4 bytes being written. The data is widened to int32 and then written;
+ // hence the position of the nonzero bytes depend on the native endianness of the CPU.
+ //
+ // Writes of primitive values with 8 byte size, double, int64_t, uint64_t,
+ // are stored with 4 byte alignment. The ARM and x86/x64 permit unaligned reads
+ // and writes (albeit with potential latency/throughput penalty) which may or may
+ // not be observable unless the process is IO bound.
+ //
+ // 2) Parcelables
+ // Parcelables are detected by the type's base class, and implemented through calling
+ // into the Parcelable type's readFromParcel() or writeToParcel() methods.
+ // Historically, due to null object detection, a (int32_t) 1 is prepended to the data written.
+ // Parcelables must have a default constructor (i.e. one that takes no arguments).
+ //
+ // 3) Arrays
+ // Arrays of uint8_t and int8_t, and enums based on size 1 are written as
+ // a contiguous packed byte stream. Hidden zero padding is applied at the end of the byte
+ // stream to make a multiple of 4 bytes (and prevent info leakage when writing).
+ //
+ // All other array writes can be conceptually thought of as recursively calling
+ // writeData on the individual elements (though may be implemented differently for speed).
+ // As discussed in (1), alignment rules are therefore applied for each element
+ // write (not as an aggregate whole), so the wire representation of data can be
+ // substantially larger.
+ //
+ // Historical Note:
+ // Because of element-wise alignment, CharVector and BoolVector are expanded
+ // element-wise into integers even though they could have been optimized to be packed
+ // just like uint8_t, int8_t (size 1 data).
+ //
+ // 3.1) Arrays accessed by the std::vector type. This is the default for AIDL.
+ //
+ // 4) Nullables
+ // std::optional, std::unique_ptr, std::shared_ptr are all parceled identically
+ // (i.e. result in identical byte layout).
+ // The target of the std::optional, std::unique_ptr, or std::shared_ptr
+ // can either be a std::vector, String16, std::string, or a Parcelable.
+ //
+ // Detection of null relies on peeking the first int32 data and checking if the
+ // the peeked value is considered invalid for the object:
+ // (-1 for vectors, String16, std::string) (0 for Parcelables). If the peeked value
+ // is invalid, then a null is returned.
+ //
+ // Application Note: When to use each nullable type:
+ //
+ // std::optional: Embeds the object T by value rather than creating a new instance
+ // by managed pointer as std::unique_ptr or std::shared_ptr. This will save a malloc
+ // when creating an optional instance.
+ //
+ // Use of std::optionals by value can result in copies of the underlying value stored in it,
+ // so a std::move may be used to move in and move out (for example) a vector value into
+ // the std::optional or for the std::optional itself.
+ //
+ // std::unique_ptr, std::shared_ptr: These are preferred when the lifetime of the object is
+ // already managed by the application. This reduces unnecessary copying of data
+ // especially when the calls are local in-proc (rather than via binder rpc).
+ //
+ // 5) StrongBinder (sp<IBinder>)
+ // StrongBinder objects are written regardless of null. When read, null StrongBinder values
+ // will be interpreted as UNKNOWN_ERROR if the type is a single argument <sp<T>>
+ // or in a vector argument <std::vector<sp<T>>. However, they will be read without an error
+ // if present in a std::optional, std::unique_ptr, or std::shared_ptr vector, e.g.
+ // <std::optional<std::vector<sp<T>>>.
+ //
+ // See AIDL annotation @Nullable, readStrongBinder(), and readNullableStrongBinder().
+ //
+ // Historical Note: writing a vector of StrongBinder objects <std::vector<sp<T>>
+ // containing a null will not cause an error. However reading such a vector will cause
+ // an error _and_ early termination of the read.
