public BitSetUtil()

方法详细资料

bitmapOf

public static RoaringBitmap bitmapOf(java.util.BitSet bitSet)

Generate a RoaringBitmap out of a BitSet

参数:

bitSet - original bitset (will not be modified)

返回:

roaring bitmap equivalent to BitSet

bitmapOf

public static RoaringBitmap bitmapOf(long[] words)

Generate a RoaringBitmap out of a long[], each long using little-endian representation of its bits

参数:

words - array of longs (will not be modified)

返回:

roaring bitmap

equals

public static boolean equals(java.util.BitSet bitset,
                             RoaringBitmap bitmap)

Compares a RoaringBitmap and a BitSet. They are equal if and only if they contain the same set of integers.

参数:

bitset - first object to be compared

bitmap - second object to be compared

返回:

whether they are equals
