/**
* Container for a message (data and object references) that can
* be sent through an IBinder. A Parcel can contain both flattened data
* that will be unflattened on the other side of the IPC (using the various
* methods here for writing specific types, or the general
* {@link Parcelable} interface), and references to live {@link IBinder}
* objects that will result in the other side receiving a proxy IBinder
* connected with the original IBinder in the Parcel.
*
* <p class="note">Parcel is <strong>not</strong> a general-purpose
* serialization mechanism. This class (and the corresponding
* {@link Parcelable} API for placing arbitrary objects into a Parcel) is
* designed as a high-performance IPC transport. As such, it is not
* appropriate to place any Parcel data in to persistent storage: changes
* in the underlying implementation of any of the data in the Parcel can
* render older data unreadable.</p>
*
* <p>The bulk of the Parcel API revolves around reading and writing data
* of various types. There are six major classes of such functions available.</p>
*
* <h3>Primitives</h3>
*
* <p>The most basic data functions are for writing and reading primitive
* data types: {@link #writeByte}, {@link #readByte}, {@link #writeDouble},
* {@link #readDouble}, {@link #writeFloat}, {@link #readFloat}, {@link #writeInt},
* {@link #readInt}, {@link #writeLong}, {@link #readLong},
* {@link #writeString}, {@link #readString}. Most other
* data operations are built on top of these. The given data is written and
* read using the endianess of the host CPU.</p>
*
* <h3>Primitive Arrays</h3>
*
* <p>There are a variety of methods for reading and writing raw arrays
* of primitive objects, which generally result in writing a 4-byte length
* followed by the primitive data items. The methods for reading can either
* read the data into an existing array, or create and return a new array.
* These available types are:</p>
*
* <ul>
* <li> {@link #writeBooleanArray(boolean[])},
* {@link #readBooleanArray(boolean[])}, {@link #createBooleanArray()}
* <li> {@link #writeByteArray(byte[])},
* {@link #writeByteArray(byte[], int, int)}, {@link #readByteArray(byte[])},
* {@link #createByteArray()}
* <li> {@link #writeCharArray(char[])}, {@link #readCharArray(char[])},
* {@link #createCharArray()}
* <li> {@link #writeDoubleArray(double[])}, {@link #readDoubleArray(double[])},
* {@link #createDoubleArray()}
* <li> {@link #writeFloatArray(float[])}, {@link #readFloatArray(float[])},
* {@link #createFloatArray()}
* <li> {@link #writeIntArray(int[])}, {@link #readIntArray(int[])},
* {@link #createIntArray()}
* <li> {@link #writeLongArray(long[])}, {@link #readLongArray(long[])},
* {@link #createLongArray()}
* <li> {@link #writeStringArray(String[])}, {@link #readStringArray(String[])},
* {@link #createStringArray()}.
* <li> {@link #writeSparseBooleanArray(SparseBooleanArray)},
* {@link #readSparseBooleanArray()}.
* </ul>
*
* <h3>Parcelables</h3>
*
* <p>The {@link Parcelable} protocol provides an extremely efficient (but
* low-level) protocol for objects to write and read themselves from Parcels.
* You can use the direct methods {@link #writeParcelable(Parcelable, int)}
* and {@link #readParcelable(ClassLoader)} or
* {@link #writeParcelableArray} and
* {@link #readParcelableArray(ClassLoader)} to write or read. These
* methods write both the class type and its data to the Parcel, allowing
* that class to be reconstructed from the appropriate class loader when
* later reading.</p>
*
* <p>There are also some methods that provide a more efficient way to work
* with Parcelables: {@link #writeTypedArray},
* {@link #writeTypedList(List)},
* {@link #readTypedArray} and {@link #readTypedList}. These methods
* do not write the class information of the original object: instead, the
* caller of the read function must know what type to expect and pass in the
* appropriate {@link Parcelable.Creator Parcelable.Creator} instead to
* properly construct the new object and read its data. (To more efficient
* write and read a single Parceable object, you can directly call
* {@link Parcelable#writeToParcel Parcelable.writeToParcel} and
* {@link Parcelable.Creator#createFromParcel Parcelable.Creator.createFromParcel}
* yourself.)</p>
*
* <h3>Bundles</h3>
*
* <p>A special type-safe container, called {@link Bundle}, is available
* for key/value maps of heterogeneous values. This has many optimizations
* for improved performance when reading and writing data, and its type-safe
* API avoids difficult to debug type errors when finally marshalling the
* data contents into a Parcel. The methods to use are
* {@link #writeBundle(Bundle)}, {@link #readBundle()}, and
* {@link #readBundle(ClassLoader)}.
*
* <h3>Active Objects</h3>
*
* <p>An unusual feature of Parcel is the ability to read and write active
* objects. For these objects the actual contents of the object is not
* written, rather a special token referencing the object is written. When
* reading the object back from the Parcel, you do not get a new instance of
* the object, but rather a handle that operates on the exact same object that
* was originally written. There are two forms of active objects available.</p>
*
* <p>{@link Binder} objects are a core facility of Android's general cross-process
* communication system. The {@link IBinder} interface describes an abstract
* protocol with a Binder object. Any such interface can be written in to
* a Parcel, and upon reading you will receive either the original object
* implementing that interface or a special proxy implementation
* that communicates calls back to the original object. The methods to use are
* {@link #writeStrongBinder(IBinder)},
* {@link #writeStrongInterface(IInterface)}, {@link #readStrongBinder()},
* {@link #writeBinderArray(IBinder[])}, {@link #readBinderArray(IBinder[])},
* {@link #createBinderArray()},
* {@link #writeBinderList(List)}, {@link #readBinderList(List)},
* {@link #createBinderArrayList()}.</p>
*
* <p>FileDescriptor objects, representing raw Linux file descriptor identifiers,
* can be written and {@link ParcelFileDescriptor} objects returned to operate
* on the original file descriptor. The returned file descriptor is a dup
* of the original file descriptor: the object and fd is different, but
* operating on the same underlying file stream, with the same position, etc.
* The methods to use are {@link #writeFileDescriptor(FileDescriptor)},
* {@link #readFileDescriptor()}.
*
* <h3>Untyped Containers</h3>
*
* <p>A final class of methods are for writing and reading standard Java
* containers of arbitrary types. These all revolve around the
* {@link #writeValue(Object)} and {@link #readValue(ClassLoader)} methods
* which define the types of objects allowed. The container methods are
