Bases: Searcher
, Updater
The diffing algorithm in Zenaura virtual DOM.
This class is responsible for comparing the old and new virtual DOM trees and generating a list of changes that need to be applied to the real DOM.
The diffing algorithm is implemented in two steps:
- Search: The
Searcher
class traverses the old and new virtual DOM trees and identifies the nodes that have changed.
- Update: The
Updater
class applies the changes to the real DOM.
The diffing algorithm is designed to be efficient and performant. It uses a number of techniques to minimize the number of changes that need to be applied to the real DOM.
Attributes:
Searcher
: An instance of the Searcher
class.
Updater
: An instance of the Updater
class.
Methods:
diff(old_tree, new_tree)
: Compares the old and new virtual DOM trees and generates a list of changes that need to be applied to the real DOM.
Example:
# Create an instance of the DiffingAlgorithm class.
diffing_algorithm = DiffingAlgorithm()
# Compare the old and new virtual DOM trees.
changes = diffing_algorithm.diff(old_tree, new_tree)
# Apply the changes to the real DOM.
diffing_algorithm.update(changes)

The diffing algorithm in Zenaura virtual DOM.
This class is responsible for comparing the old and new virtual DOM trees and generating a list of changes that need to be applied to the real DOM.
The diffing algorithm is implemented in two steps:
1. **Search:** The `Searcher` class traverses the old and new virtual DOM trees and identifies the nodes that have changed.
2. **Update:** The `Updater` class applies the changes to the real DOM.
The diffing algorithm is designed to be efficient and performant. It uses a number of techniques to minimize the number of changes that need to be applied to the real DOM.
**Attributes:**
* `Searcher`: An instance of the `Searcher` class.
* `Updater`: An instance of the `Updater` class.
**Methods:**
* `diff(old_tree, new_tree)`: Compares the old and new virtual DOM trees and generates a list of changes that need to be applied to the real DOM.
**Example:**
```python
# Create an instance of the DiffingAlgorithm class.
diffing_algorithm = DiffingAlgorithm()
# Compare the old and new virtual DOM trees.
changes = diffing_algorithm.diff(old_tree, new_tree)
# Apply the changes to the real DOM.
