Node.js v8.Deserializer.readUint32() Method

The v8.Deserializer.readUint32() method is an inbuilt application programming interface of the v8.Deserializer module which is used to read a raw 32-bit unsigned integer value from the buffer. For use inside of custom Deserializer._readHostObject().

Syntax:

v8.Deserializer.readUint32();

Parameters: This method does not accept any parameters.

Return Value: This method reads raw 32-bit unsigned integer value from the buffer and returns it.

Below examples illustrate the use of v8.Deserializer.readUint32() method in Node.js:

Example 1: Filename: index.js

// Accessing v8 module
const v8 = require('v8');
const serializer = new v8.Serializer();

// Calling v8.serializer.writeUint32()
serializer.writeUint32(5783);

// Calling v8.deserializer.readUint32()
const deserializer = new v8.Deserializer(
            serializer.releaseBuffer());
console.log(deserializer.readUint32());

Run index.js file using the following command:

node index.js

Output:

5783

Example 2: Filename: index.js

// Accessing v8 module
const v8 = require('v8');
const serializer = new v8.Serializer();

// Calling v8.serializer.writeUint32()
console.log(serializer.releaseBuffer());
serializer.writeUint32(29698);
buff = serializer.releaseBuffer();
console.log("buffer data is:");
console.log(buff);

// Calling v8.deserializer.readUint32()
const deserializer = new v8.Deserializer(buff);
console.log("deserialized data: ");
console.log(deserializer.readUint32());

Run index.js file using the following command:

node index.js

Output:

<Buffer >
buffer data is:
<Buffer 82 e8 01>
deserialized data:
29698
