The v8.Serializer.writeUint32() method is an inbuilt application programming interface of the v8.Serializer module, which is used to write the raw 32-bit integer value to the internal buffer. For use inside of custom serializer._writeHostObject().
Syntax:v8.Serializer.writeUint32( value );
Parameters: This method accepts single parameter as mentioned above and described below.
- value: It is a required parameter, refers to a 32-bit integer to be written to the internal buffer.
Return Value: This method does not return anything but writes a raw 32-bit integer value to the internal buffer.
Below examples illustrate the use of v8.Serializer.writeUint32() 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()
// The undefined will be logged in
// console as this function does not
// return anything
console.log(serializer.writeUint32(5783));
console.log(serializer.releaseBuffer());
node index.js
Output:
Undefined <Buffer 97 2d>
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);
console.log(serializer.releaseBuffer());
// Writing two 32 bits number one
// after another
console.log("writing two 32 bits "
+ "number one after another");
serializer.writeUint32(29698);
serializer.writeUint32(29698);
console.log(serializer.releaseBuffer());
console.log("reading after write");
// Calling v8.serializer.writeUint32()
serializer.writeUint32(5783);
// Calling v8.deserializer.readUint32()
const deserializer = new
v8.Deserializer(serializer.releaseBuffer());
console.log(deserializer.readUint32());
node index.js
Output:
<Buffer > <Buffer 82 e8 01> writing two 32 bits number one after another <Buffer 82 e8 01 82 e8 01> reading after write 5783
