Class ZstdInputStreamNoFinalizer

java.lang.Object

java.io.InputStream

java.io.FilterInputStream

com.github.luben.zstd.ZstdInputStreamNoFinalizer

All Implemented Interfaces:

Closeable, AutoCloseable

public class ZstdInputStreamNoFinalizer
extends FilterInputStream

InputStream filter that decompresses the data provided by the underlying InputStream using Zstd compression. It does not support mark/reset methods. It also does not have finalizer, so if you rely on finalizers to clean the native memory and release buffers use `ZstdInputStream` instead.
