crc32(string $value) : string

This helper wraps the ArangoDB AQL function CRC32(text) which calculates the CRC32 checksum for the given text and returns it as a hexadecimal string. The polynomial used is 0x1EDC6F41 with initial value 0xFFFFFFFF and final XOR 0xFFFFFFFF.

Example AQL usage:

CRC32("hello")                // returns "3610a686"
CRC32("world")                // returns "4a17b156"
CRC32(doc.content)            // returns CRC32 checksum of content
Parameters
$value : string

String expression to calculate CRC32 checksum for.
