Lucene.Net
3.0.3
Lucene.Net is a port of the Lucene search engine library, written in C# and targeted at .NET runtime users.

Optimized implementation of a vector of bits. This is more-or-less like java.util.BitSet, but also includes the following:
Inherits ICloneable.
Public Member Functions | |
BitVector (int n) | |
Constructs a vector capable of holding n bits. | |
System.Object | Clone () |
void | Set (int bit) |
Sets the value of bit to one. | |
bool | GetAndSet (int bit) |
Sets the value of bit to true, and returns true if bit was already set | |
void | Clear (int bit) |
Sets the value of bit to zero. | |
bool | Get (int bit) |
Returns true if bit is one and false if it is zero. | |
int | Size () |
Returns the number of bits in this vector. This is also one greater than the number of the largest valid bit number. | |
int | Count () |
Returns the total number of one bits in this vector. This is efficiently computed and cached, so that, if the vector is not changed, no recomputation is done for repeated calls. | |
int | GetRecomputedCount () |
For testing | |
void | Write (Directory d, System.String name) |
Writes this vector to the file name in Directory d , in a format that can be read by the constructor BitVector(Directory, String). | |
BitVector (Directory d, System.String name) | |
Constructs a bit vector from the file name in Directory d , as written by the Write method. | |
BitVector | Subset (int start, int end) |
Retrieve a subset of this BitVector. | |
