C# Класс Lucene.Net.Util.FixedBitSet

BitSet of fixed length (numBits), backed by accessible (#getBits) long[], accessed with an int index, implementing GetBits and DocIdSet. If you need to manage more than 2.1B bits, use LongBitSet. @lucene.internal

Метод	Описание
And ( DocIdSetIterator iter ) : void	Does in-place AND of the bits provided by the iterator.
And ( FixedBitSet other ) : void	this = this AND other
AndNot ( DocIdSetIterator iter ) : void	Does in-place AND NOT of the bits provided by the iterator.
AndNot ( FixedBitSet other ) : void	this = this AND NOT other
AndNotCount ( FixedBitSet a, FixedBitSet b ) : long	Returns the popcount or cardinality of "a and not b" or "intersection(a, not(b))". Neither set is modified.
Bits2words ( int numBits ) : int	returns the number of 64 bit words it would take to hold numBits
Cardinality ( ) : int	Returns number of set bits. NOTE: this visits every long in the backing bits array, and the result is not internally cached!
Clear ( int index ) : void
Clear ( int startIndex, int endIndex ) : void	Clears a range of bits.
Clone ( ) : FixedBitSet
EnsureCapacity ( FixedBitSet bits, int numBits ) : FixedBitSet	If the given FixedBitSet is large enough to hold {@code numBits}, returns the given bits, otherwise returns a new FixedBitSet which can hold the requested number of bits. NOTE: the returned bitset reuses the underlying {@code long[]} of the given {@code bits} if possible. Also, calling #length() on the returned bits may return a value greater than {@code numBits}.
Equals ( object o ) : bool	returns true if both sets have the same bits set
FixedBitSet ( int numBits ) : System
FixedBitSet ( long storedBits, int numBits ) : System
Flip ( int startIndex, int endIndex ) : void	Flips a range of bits
Get ( int index ) : bool
GetAndClear ( int index ) : bool
GetAndSet ( int index ) : bool
GetBits ( ) : Bits
GetHashCode ( ) : int
GetIterator ( ) : DocIdSetIterator
IntersectionCount ( FixedBitSet a, FixedBitSet b ) : long	Returns the popcount or cardinality of the intersection of the two sets. Neither set is modified.
Intersects ( FixedBitSet other ) : bool	returns true if the sets have any elements in common
Length ( ) : int
NextSetBit ( int index ) : int	Returns the index of the first set bit starting at the index specified. -1 is returned if there are no more set bits.
Or ( DocIdSetIterator iter ) : void	Does in-place OR of the bits provided by the iterator.
Or ( FixedBitSet other ) : void	this = this OR other
PrevSetBit ( int index ) : int	Returns the index of the last set bit before or on the index specified. -1 is returned if there are no more set bits.
Set ( int index ) : void
Set ( int startIndex, int endIndex ) : void	Sets a range of bits
UnionCount ( FixedBitSet a, FixedBitSet b ) : long	Returns the popcount or cardinality of the union of the two sets. Neither set is modified.
Xor ( DocIdSetIterator iter ) : void	Does in-place XOR of the bits provided by the iterator.
Xor ( FixedBitSet other ) : void	this = this XOR other
