Method Details

crc32cImplementation

public static SdkChecksum crc32cImplementation()

Tries to create a Java 9-based CRC32C checksum. If it's not available, it tries to create a CRT-based checksum. If both are not available, it falls back to an SDK-based CRC32C checksum.

Returns:

An instance of SdkChecksum, based on the first available option.
