LzfDecoder
public LzfDecoder()Creates a new LZF decoder with the most optimal available methods for underlying data access. It will "unsafe" instance if one can be used on current JVM. It should be safe to call this constructor as implementations are dynamically loaded; however, on some non-standard platforms it may be necessary to useLzfDecoder(boolean)withtrueparam. -
LzfDecoder
public LzfDecoder(boolean safeInstance) Creates a new LZF decoder with specified decoding instance.- Parameters:
safeInstance- Iftruedecoder will useChunkDecoderthat only uses standard JDK access methods, and should work on all Java platforms and JVMs. Otherwise decoder will try to use highly optimizedChunkDecoderimplementation that uses Sun JDK'sUnsafeclass (which may be included by other JDK's as well).
