Class Int64BitSet

BitSet of fixed length (Lucene.Net.Util.Int64BitSet.numBits), backed by accessible (GetBits()) long[], accessed with a index. Use it only if you intend to store more than 2.1B bits, otherwise you should use FixedBitSet.

NOTE: This was LongBitSet in Lucene

Properties

Name Description
Length

Returns the number of bits stored in this bitset.

Methods

Name Description
And(Int64BitSet)

this = this AND other

AndNot(Int64BitSet)

this = this AND NOT other

Bits2words(Int64)

Returns the number of 64 bit words it would take to hold numBits.

Cardinality()

Returns number of set bits. NOTE: this visits every long in the backing bits array, and the result is not internally cached!
Clear(Int64)
Clear(Int64, Int64)

Clears a range of bits.
Clone()
EnsureCapacity(Int64BitSet, Int64)

If the given Int64BitSet is large enough to hold numBits, returns the given bits, otherwise returns a new Int64BitSet which can hold the requested number of bits.

NOTE: the returned bitset reuses the underlying long[] of the given bits if possible. Also, reading Length on the returned bits may return a value greater than numBits.
Equals(Object)

Returns true if both sets have the same bits set

Flip(Int64, Int64)

Flips a range of bits
Get(Int64)
GetAndClear(Int64)
GetAndSet(Int64)
GetBits()

Expert.

GetHashCode()
Intersects(Int64BitSet)

Returns true if the sets have any elements in common

NextSetBit(Int64)

Returns the index of the first set bit starting at the index specified. -1 is returned if there are no more set bits.
Or(Int64BitSet)

this = this OR other

PrevSetBit(Int64)

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(Int64)
Set(Int64, Int64)

Sets a range of bits
Xor(Int64BitSet)

this = this XOR other
