The NodeJsonDecoder class in UssElement provides the functionality to deserializing JSON strings back into Node objects. This feature allows for seamless bidirectional data transfer, ensuring that Nodes can be reconstructed from their JSON representations without losing structural or attribute integrity.

Constructor

public NodeJsonDecoder::__construct(string $json)

The constructor accepts a JSON string, which represents the serialized form of a Node object or Node tree.

Example

use Ucscode\UssElement\Serializer\NodeJsonDecoder;

// JSON representation of a Node
$json = '{
    "nodeId": 1,
    "nodeType": 1,
    "nodeName": "DIV",
    "parentId": null,
    "attributes": {
        "class": "container"
    },
    "void": false,
    "visible": true,
    "meta": [],
    "childNodes": [
        {
            "nodeId": 2,
            "nodeType": 1,
            "nodeName": "INPUT",
            "parentId": 1,
            "attributes": {
                "class": "form-control",
                "name": "username"
            },
            "void": true,
            "visible": true,
            "meta": [],
            "childNodes": []
        }
    ]
}';

// Initialize the decoder
$decoder = new NodeJsonDecoder($json);

// Reconstruct the Node object
$node = $decoder->decode();

echo $node->getTagName(); // Outputs: DIV
echo $node->getAttribute('class'); // Outputs: container

// Query child node
$node->querySelector('.form-control'); // Return an "INPUT" element
