C# Class Lucene.Net.Util.LongBitSet

BitSet of fixed length (numBits), backed by accessible (#getBits) long[], accessed with a long index. Use it only if you intend to store more than 2.1B bits, otherwise you should use FixedBitSet. @lucene.internal

Public Methods

Method	Description
And ( LongBitSet other ) : void	this = this AND other
AndNot ( LongBitSet other ) : void	this = this AND NOT other
Bits2words ( long numBits ) : int	returns the number of 64 bit words it would take to hold numBits
Cardinality ( ) : long	Returns number of set bits. NOTE: this visits every long in the backing bits array, and the result is not internally cached!
Clear ( long index ) : void
Clear ( long startIndex, long endIndex ) : void	Clears a range of bits.
Clone ( ) : LongBitSet
EnsureCapacity ( LongBitSet bits, long numBits ) : LongBitSet	If the given LongBitSet is large enough to hold {@code numBits}, returns the given bits, otherwise returns a new LongBitSet 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
Flip ( long startIndex, long endIndex ) : void	Flips a range of bits
Get ( long index ) : bool
GetAndClear ( long index ) : bool
GetAndSet ( long index ) : bool
GetHashCode ( ) : int
Intersects ( LongBitSet other ) : bool	returns true if the sets have any elements in common
Length ( ) : long	Returns the number of bits stored in this bitset.
LongBitSet ( long numBits ) : Lucene.Net.Support
LongBitSet ( long storedBits, long numBits ) : Lucene.Net.Support
NextSetBit ( long index ) : long	Returns the index of the first set bit starting at the index specified. -1 is returned if there are no more set bits.
Or ( LongBitSet other ) : void	this = this OR other
PrevSetBit ( long index ) : long	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 ( long index ) : void
Set ( long startIndex, long endIndex ) : void	Sets a range of bits
Xor ( LongBitSet other ) : void	this = this XOR other
