io.github.mahmoudimus.zstd.ZstdInputStream

All Implemented Interfaces:

Closeable, AutoCloseable

public final class ZstdInputStream
extends InputStream

Decompresses Zstandard data read from another stream. Output is produced a block (at most 128 KiB) at a time, so reading a capped amount from a hostile stream costs no more than that much work and memory, plus the frame's window.
