Class WaarpZstdCodec

java.lang.Object

org.waarp.compress.WaarpZstdCodec

public class WaarpZstdCodec
extends Object

Waarp Compression Codec using byte array.
This will try to use one of the three implementations, according to environment, in the following order:

• JNI based: the fastest, best compression ratio and less CPU
• Unsafe based: 2 times slower than JNI but almost same in ratio and a bit more CPU
• Safe based: 4 times slower than JNI but almost same in ratio and a bit more CPU
