# DataBuffer - Summary This section provides an overview of the `DataBuffer` class, which is responsible for serializing and deserializing objects in byte format. The `DataBuffer` class is crucial for managing the storage and retrieval of objects in a raw, byte-oriented format. ## Purpose The `DataBuffer` class allows for efficient storage and retrieval of objects in a byte format. It supports the serialization of objects to a byte buffer and deserialization from it, providing an easy-to-use interface via `<<` and `>>` operators. ## Key Features: - **Polymorphic serialization**: The class can serialize a wide range of objects, including basic types and custom classes, to a byte buffer. - **Deserialization**: The class also supports deserialization, reading objects from the byte buffer back into their original form. - **Operator overloading**: The `<<` and `>>` operators are overloaded to handle both serialization and deserialization for various types. - **Buffer management**: The internal buffer is dynamically resized as needed to store serialized data. ## Methods: - **operator<< (const T&)**: Serializes an object of type `T` and appends it to the buffer. - **operator>> (T&)**: Deserializes an object of type `T` from the buffer. - **getData**: Retrieves the raw byte data stored in the buffer. ## Example Usage: ### Serializing and Deserializing Basic Types ```cpp DataBuffer buffer; int number = 42; // Serialize an integer buffer << number; // Deserialize the integer int deserializedNumber; buffer >> deserializedNumber; std::cout << "Deserialized number: " << deserializedNumber << std::endl; // Output: 42 ``` ### Serializing and Deserializing Custom Objects ``` class TestObject { public: int x; std::string y; friend DataBuffer& operator<<(DataBuffer& p_buffer, const TestObject& p_object) { p_buffer << p_object.x << p_object.y; return p_buffer; } friend DataBuffer& operator>>(DataBuffer& p_buffer, TestObject& p_object) { p_buffer >> p_object.x >> p_object.y; return p_buffer; } }; DataBuffer buffer; TestObject obj1{42, "Hello"}; // Serialize a custom object buffer << obj1; // Deserialize the object TestObject deserializedObj; buffer >> deserializedObj; std::cout << "Deserialized object: x = " << deserializedObj.x << ", y = " << deserializedObj.y << std::endl; ```
