Scala Serialize Object To Byte Array

Scala Serialize Object To Byte Array 3,7/5 2550 votes

Is there a way to deserialize an object in unmanaged C++? If not, does anyone know what algorithm is used to serialize a byte array to the output found in the xml? It doesn't just print out the array of bytes, some sort of conversion is used that doesn't match directly to a byte array.

Deep clone an Object using serialization. This is many times slower than writing clone methods by hand on all objects in your object graph.

However, for complex object graphs, or for those that don't support deep cloning this can be a simple alternative implementation. Of course all the objects must be Serializable.

Type Parameters: T - the type of the object involved Parameters: object - the Serializable object to clone Returns: the cloned object Throws: - (runtime) if the serialization fails • roundtrip public static  T (T msg). Serializes an Object to the specified stream. The stream will be closed once the object is written.

This avoids the need for a finally clause, and maybe also exception handling, in the application code. The stream passed in is not buffered internally within this method. This is the responsibility of your application if desired. Parameters: obj - the object to serialize to bytes, may be null outputStream - the stream to write to, must not be null Throws: - if outputStream is null - (runtime) if the serialization fails • serialize public static byte[] ( obj). Deserializes an Object from the specified stream. The stream will be closed once the object is written. This avoids the need for a finally clause, and maybe also exception handling, in the application code.

The stream passed in is not buffered internally within this method. This is the responsibility of your application if desired. If the call site incorrectly types the return value, a is thrown from the call site. Without Generics in this declaration, the call site must type cast and can cause the same ClassCastException.

Note that in both cases, the ClassCastException is in the call site, not in this method. Type Parameters: T - the object type to be deserialized Parameters: inputStream - the serialized object input stream, must not be null Returns: the deserialized object Throws: - if inputStream is null - (runtime) if the serialization fails • deserialize public static  T (byte[] objectData). Deserializes a single Object from an array of bytes.

Note that in both cases, the ClassCastException is in the call site, not in this method. Type Parameters: T - the object type to be deserialized Parameters: objectData - the serialized object, must not be null Returns: the deserialized object Throws: - if objectData is null - (runtime) if the serialization fails.
