Node.js v8.Deserializer.readValue() Method
The v8.Deserializer.readValue() method is an inbuilt application programming interface of the v8.Deserializer module which is used to read the JS value from serialized data as present in a buffer.
Syntax:
v8.Deserializer.readValue();
Parameters: This method does not accept any parameters.
Return Value: This method reads JS value from serialized representation as present in a buffer and returns it on successful reading.
Below examples illustrate the use of v8.Deserializer.readValue() method in Node.js:
Example 1: Filename: index.js
// Accessing v8 module const v8 = require('v8'); const serializer = new v8.Serializer(); // Calling v8.serializer.writeValue() console.log(serializer.writeValue("w3wiki")); // Calling v8.deserializer.readValue() const deserializer = new v8.Deserializer( serializer.releaseBuffer()); console.log(deserializer.readValue()); |
Run index.js file using the following command:
node index.js
Output:
true w3wiki
Example 2: Filename: index.js
// Accessing v8 module const v8 = require('v8'); const serializer = new v8.Serializer(); // Calling v8.serializer.writeValue() console.log(serializer.writeValue(839475.3495)); buff = serializer.releaseBuffer(); console.log("buffer data is:"); console.log(buff); // Calling v8.deserializer.readValue() const deserializer = new v8.Deserializer(buff); console.log("deserialized data: " + deserializer.readValue()); |
Run index.js file using the following command:
node index.js
Output:
true buffer data is: <Buffer 4e fc a9 f1 b2 66 9e 29 41> deserialized data: 839475.3495
