Method Detail

length

public static int length(Object[] buf)

modifiedCalcCircularRefElementOffset

public static long modifiedCalcCircularRefElementOffset(long index,
                                                        long mask)

This method assumes index is actually (index << 1) because lower bit is used for resize. This is compensated for by reducing the element shift. The computation is constant folded, so there's no cost.

nextArrayOffset

public static long nextArrayOffset(Object[] curr)
