| 45 | /** |
| 46 | * Container for a message (data and object references) that can |
| 47 | * be sent through an IBinder. A Parcel can contain both flattened data |
| 48 | * that will be unflattened on the other side of the IPC (using the various |
| 49 | * methods here for writing specific types, or the general |
| 50 | * {@link Parcelable} interface), and references to live {@link IBinder} |
| 51 | * objects that will result in the other side receiving a proxy IBinder |
| 52 | * connected with the original IBinder in the Parcel. |
| 53 | * |
| 54 | * <p class="note">Parcel is <strong>not</strong> a general-purpose |
| 55 | * serialization mechanism. This class (and the corresponding |
| 56 | * {@link Parcelable} API for placing arbitrary objects into a Parcel) is |
| 57 | * designed as a high-performance IPC transport. As such, it is not |
| 58 | * appropriate to place any Parcel data in to persistent storage: changes |
| 59 | * in the underlying implementation of any of the data in the Parcel can |
| 60 | * render older data unreadable.</p> |
| 61 | * |
| 62 | * <p>The bulk of the Parcel API revolves around reading and writing data |
| 63 | * of various types. There are six major classes of such functions available.</p> |
| 64 | * |
| 65 | * <h3>Primitives</h3> |
| 66 | * |
| 67 | * <p>The most basic data functions are for writing and reading primitive |
| 68 | * data types: {@link #writeByte}, {@link #readByte}, {@link #writeDouble}, |
| 69 | * {@link #readDouble}, {@link #writeFloat}, {@link #readFloat}, {@link #writeInt}, |
| 70 | * {@link #readInt}, {@link #writeLong}, {@link #readLong}, |
| 71 | * {@link #writeString}, {@link #readString}. Most other |
| 72 | * data operations are built on top of these. The given data is written and |
| 73 | * read using the endianess of the host CPU.</p> |
| 74 | * |
| 75 | * <h3>Primitive Arrays</h3> |
| 76 | * |
| 77 | * <p>There are a variety of methods for reading and writing raw arrays |
| 78 | * of primitive objects, which generally result in writing a 4-byte length |
| 79 | * followed by the primitive data items. The methods for reading can either |
| 80 | * read the data into an existing array, or create and return a new array. |
| 81 | * These available types are:</p> |
| 82 | * |
| 83 | * <ul> |
| 84 | * <li> {@link #writeBooleanArray(boolean[])}, |
| 85 | * {@link #readBooleanArray(boolean[])}, {@link #createBooleanArray()} |
| 86 | * <li> {@link #writeByteArray(byte[])}, |
| 87 | * {@link #writeByteArray(byte[], int, int)}, {@link #readByteArray(byte[])}, |
| 88 | * {@link #createByteArray()} |
| 89 | * <li> {@link #writeCharArray(char[])}, {@link #readCharArray(char[])}, |
| 90 | * {@link #createCharArray()} |
| 91 | * <li> {@link #writeDoubleArray(double[])}, {@link #readDoubleArray(double[])}, |
| 92 | * {@link #createDoubleArray()} |
| 93 | * <li> {@link #writeFloatArray(float[])}, {@link #readFloatArray(float[])}, |
| 94 | * {@link #createFloatArray()} |
| 95 | * <li> {@link #writeIntArray(int[])}, {@link #readIntArray(int[])}, |
| 96 | * {@link #createIntArray()} |
| 97 | * <li> {@link #writeLongArray(long[])}, {@link #readLongArray(long[])}, |
| 98 | * {@link #createLongArray()} |
| 99 | * <li> {@link #writeStringArray(String[])}, {@link #readStringArray(String[])}, |
| 100 | * {@link #createStringArray()}. |
| 101 | * <li> {@link #writeSparseBooleanArray(SparseBooleanArray)}, |
| 102 | * {@link #readSparseBooleanArray()}. |
| 103 | * </ul> |
| 104 | * |
| 105 | * <h3>Parcelables</h3> |
| 106 | * |
| 107 | * <p>The {@link Parcelable} protocol provides an extremely efficient (but |
| 108 | * low-level) protocol for objects to write and read themselves from Parcels. |
| 109 | * You can use the direct methods {@link #writeParcelable(Parcelable, int)} |
| 110 | * and {@link #readParcelable(ClassLoader)} or |
| 111 | * {@link #writeParcelableArray} and |
| 112 | * {@link #readParcelableArray(ClassLoader)} to write or read. These |
| 113 | * methods write both the class type and its data to the Parcel, allowing |
| 114 | * that class to be reconstructed from the appropriate class loader when |
| 115 | * later reading.</p> |
| 116 | * |
| 117 | * <p>There are also some methods that provide a more efficient way to work |
Jens Ole Lauridsen | 8dea874 | 2015-04-20 11:18:51 -0700 | [diff] [blame^] | 118 | * with Parcelables: {@link #writeTypedObject}, {@link #writeTypedArray}, |
| 119 | * {@link #writeTypedList}, {@link #readTypedObject}, |
| 120 | * {@link #createTypedArray} and {@link #createTypedArrayList}. These methods |
The Android Open Source Project | 9066cfe | 2009-03-03 19:31:44 -0800 | [diff] [blame] | 121 | * do not write the class information of the original object: instead, the |
| 122 | * caller of the read function must know what type to expect and pass in the |
| 123 | * appropriate {@link Parcelable.Creator Parcelable.Creator} instead to |
| 124 | * properly construct the new object and read its data. (To more efficient |
Jens Ole Lauridsen | 8dea874 | 2015-04-20 11:18:51 -0700 | [diff] [blame^] | 125 | * write and read a single Parceable object that is not null, you can directly |
| 126 | * call {@link Parcelable#writeToParcel Parcelable.writeToParcel} and |
The Android Open Source Project | 9066cfe | 2009-03-03 19:31:44 -0800 | [diff] [blame] | 127 | * {@link Parcelable.Creator#createFromParcel Parcelable.Creator.createFromParcel} |
| 128 | * yourself.)</p> |
| 129 | * |
| 130 | * <h3>Bundles</h3> |
| 131 | * |
| 132 | * <p>A special type-safe container, called {@link Bundle}, is available |
| 133 | * for key/value maps of heterogeneous values. This has many optimizations |
| 134 | * for improved performance when reading and writing data, and its type-safe |
| 135 | * API avoids difficult to debug type errors when finally marshalling the |
| 136 | * data contents into a Parcel. The methods to use are |
| 137 | * {@link #writeBundle(Bundle)}, {@link #readBundle()}, and |
| 138 | * {@link #readBundle(ClassLoader)}. |
| 139 | * |
| 140 | * <h3>Active Objects</h3> |
| 141 | * |
| 142 | * <p>An unusual feature of Parcel is the ability to read and write active |
| 143 | * objects. For these objects the actual contents of the object is not |
| 144 | * written, rather a special token referencing the object is written. When |
| 145 | * reading the object back from the Parcel, you do not get a new instance of |
| 146 | * the object, but rather a handle that operates on the exact same object that |
| 147 | * was originally written. There are two forms of active objects available.</p> |
| 148 | * |
| 149 | * <p>{@link Binder} objects are a core facility of Android's general cross-process |
| 150 | * communication system. The {@link IBinder} interface describes an abstract |
| 151 | * protocol with a Binder object. Any such interface can be written in to |
| 152 | * a Parcel, and upon reading you will receive either the original object |
| 153 | * implementing that interface or a special proxy implementation |
| 154 | * that communicates calls back to the original object. The methods to use are |
| 155 | * {@link #writeStrongBinder(IBinder)}, |
| 156 | * {@link #writeStrongInterface(IInterface)}, {@link #readStrongBinder()}, |
| 157 | * {@link #writeBinderArray(IBinder[])}, {@link #readBinderArray(IBinder[])}, |
| 158 | * {@link #createBinderArray()}, |
| 159 | * {@link #writeBinderList(List)}, {@link #readBinderList(List)}, |
| 160 | * {@link #createBinderArrayList()}.</p> |
| 161 | * |
| 162 | * <p>FileDescriptor objects, representing raw Linux file descriptor identifiers, |
| 163 | * can be written and {@link ParcelFileDescriptor} objects returned to operate |
| 164 | * on the original file descriptor. The returned file descriptor is a dup |
| 165 | * of the original file descriptor: the object and fd is different, but |
| 166 | * operating on the same underlying file stream, with the same position, etc. |
| 167 | * The methods to use are {@link #writeFileDescriptor(FileDescriptor)}, |
| 168 | * {@link #readFileDescriptor()}. |
| 169 | * |
| 170 | * <h3>Untyped Containers</h3> |
| 171 | * |
| 172 | * <p>A final class of methods are for writing and reading standard Java |
| 173 | * containers of arbitrary types. These all revolve around the |
| 174 | * {@link #writeValue(Object)} and {@link #readValue(ClassLoader)} methods |
| 175 | * which define the types of objects allowed. The container methods are |
| 176 | * {@link #writeArray(Object[])}, {@link #readArray(ClassLoader)}, |
| 177 | * {@link #writeList(List)}, {@link #readList(List, ClassLoader)}, |
| 178 | * {@link #readArrayList(ClassLoader)}, |
| 179 | * {@link #writeMap(Map)}, {@link #readMap(Map, ClassLoader)}, |
| 180 | * {@link #writeSparseArray(SparseArray)}, |
| 181 | * {@link #readSparseArray(ClassLoader)}. |
