Snapshot

Snapshot - Dart

The Snapshot pattern captures and restores the state of an object or system, allowing for rollbacks or efficient re-initialization. This is achieved by serializing the object’s state to a persistent storage (like a file) and then deserializing it to recreate that state. In Dart, this is naturally implemented …

Snapshot - Scala

The Snapshot pattern captures the state of an object or data structure at a specific point in time without affecting the original. This allows for consistent reads, especially in concurrent environments, or for implementing undo/redo functionality. This Scala example uses immutable data structures (case classes) to …

Snapshot - PHP

The Snapshot pattern allows capturing and restoring the internal state of an object. This is useful for implementing features like undo/redo, transaction rollback, or saving game progress. The code defines a Report class representing the object whose state needs to be saved. A ReportSnapshot class stores the state of …

Snapshot - Ruby

The Snapshot pattern allows saving and restoring the internal state of an object. This is useful for implementing features like undo/redo, checkpoints, or transaction rollback. The core idea is to encapsulate the object’s state into a separate snapshot object, enabling reverting to that saved state without …

Snapshot - Swift

The Snapshot pattern captures and restores the state of an object, allowing for easy undo/redo functionality or saving/loading of progress. It’s implemented here using Swift’s Codable protocol to serialize the object’s state into a snapshot (a dictionary in this case). The takeSnapshot() method …

Snapshot - Kotlin

The Snapshot pattern captures the state of an object at a specific point in time without affecting the original object. This allows for operations like undo/redo, transaction rollback, or simply observing a past state. In this Kotlin example, we use data classes and copy() to create immutable snapshots of a SystemState …

Snapshot - Rust

The Snapshot pattern captures and stores the internal state of an object at a specific point in time, allowing for rollback to that state. This is useful for implementing undo/redo functionality, checkpoints, or transaction management. The Rust implementation uses the Clone trait to create copies of the object’s …

Snapshot - Go

The Snapshot pattern captures and restores the state of an object, allowing for easy rollbacks or saving/loading of progress. It’s particularly useful in scenarios like undo/redo functionality, game save states, or transaction management. In this Go example, we define a Report struct representing the object whose …

Snapshot - C

The Snapshot pattern captures and stores the internal state of an object at a specific point in time, allowing for restoration to that state later. This is useful for implementing undo/redo functionality, checkpoints, or transaction rollback. The C implementation uses a struct to hold the object’s state and …

Snapshot - C++

The Snapshot pattern allows capturing and restoring the internal state of an object. It’s useful for implementing features like undo/redo, transaction rollback, or saving game states. This implementation uses a separate Snapshot class to hold the state, and a Memento class to provide a controlled interface for …
