checkLevel

static void checkLevel(Ruby runtime,

checkWindowBits

static void checkWindowBits(Ruby runtime,
 int wbits,
 boolean forInflate)

We only do windowBits=15(32K buffer, LZ77 algorithm) since java.util.zip only allows it. NOTE: deflateInit2 of zlib.c also accepts MAX_WBITS + 16(gzip compression). inflateInit2 also accepts MAX_WBITS + 16(gzip decompression) and MAX_WBITS + 32(automatic detection of gzip and LZ77).

checkStrategy

static void checkStrategy(Ruby runtime,
 int strategy)
