Node.js v8.Deserializer.readUint64() Method

The v8.Deserializer.readUint64() method is an inbuilt application programming interface of the v8.Deserializer module which is used to read a raw 64-bit unsigned integer value from the buffer as an array of 32-bit integers, higher and lower 32-bits separated. For use inside of custom Deserializer._readHostObject().

Syntax:

v8.Deserializer.readUint64();

Parameters: This method does not accept any parameters.

Return Value: This method reads raw 64-bit unsigned integer value from the buffer as an array of two 32-bits integer, higher and lower 32-bits separated, and returns it.

Below examples illustrate the use of v8.Deserializer.readUint64() method in Node.js:

Example 1: Filename: index.js Run index.js file using the following command:

node index.js

Output:

[ 6783, 348072 ]

Example 2: Filename: index.js Run index.js file using the following command:

node index.js

Output:

buffer data is:
<Buffer c0 8f 82 80 a0 80 1d>
higher 32-bits=29698 and lower 32-bits=34752
