public static int getMemoryUsage(int mode,
                                 int dictSize,
                                 int extraSizeBefore,
                                 int mf)

getInstance

public static LZMAEncoder getInstance(RangeEncoder rc,
                                      int lc,
                                      int lp,
                                      int pb,

                                      ArrayCache arrayCache)

putArraysToCache

public void putArraysToCache(ArrayCache arrayCache)

getDistSlot

public static int getDistSlot(int dist)

Gets an integer [0, 63] matching the highest two bits of an integer. This is like bit scan reverse (BSR) on x86 except that this also cares about the second highest bit.

getLZEncoder

public LZEncoder getLZEncoder()

reset

public void reset()

getUncompressedSize

public int getUncompressedSize()

resetUncompressedSize

public void resetUncompressedSize()

encodeForLZMA1

public void encodeForLZMA1()
                    throws IOException

Compress for LZMA1.

Throws:

IOException

encodeLZMA1EndMarker

public void encodeLZMA1EndMarker()
                          throws IOException

Throws:

IOException

encodeForLZMA2

public boolean encodeForLZMA2()

Compresses for LZMA2.

Returns:

true if the LZMA2 chunk became full, false otherwise
