BitVector

class BitVector : Iterable<Int> (source)

Performance optimized bitset implementation. Certain operations are prefixed with unsafe; these methods perform no validation.

Constructors

<init>

BitVector()BitVector(copyFrom: BitVector)

Creates a bit set based off another bit vector.

Properties

isEmpty	`val isEmpty: Boolean`
words	`var words: IntArray` (can be manipulated directly)

Functions

and	`fun and(other: BitVector): Unit` Performs a logical AND of this target bit set with the argument bit set. This bit set is modified so that each bit in it has the value true if and only if it both initially had the value true and the corresponding bit in the bit set argument also had the value true.
andNot	`fun andNot(other: BitVector): Unit` Clears all of the bits in this bit set whose corresponding bit is set in the specified bit set.
cardinality	`fun cardinality(): Int` Returns the count of `true` bits
clear	`fun clear(index: Int): Unitfun clear(): Unit` Clears the entire bitset
contains	`operator fun contains(other: BitVector): Boolean` Returns true if this bit set is a super set of the specified set, i.e. it has all bits set to true that are also set to true in the specified BitVector.
copy	`fun copy(): BitVector`
ensureCapacity	`fun ensureCapacity(bits: Int): Unit` Grows the backing array so that it can hold the requested bits. Mostly applicable when relying on the `unsafe` methods, including unsafeGet and unsafeClear.
equals	`fun equals(obj: Any?): Boolean`
flip	`fun flip(index: Int): Unit`
forEachBit	`fun forEachBit(f: (Int) -> Unit): Unit` Enumerates over all `true` bits sequeneially. This function performs better than forEach and any other functions from `Iterable<Int>`.
get	`operator fun get(index: Int): Boolean`
hashCode	`fun hashCode(): Int`
intersects	`fun intersects(other: BitVector): Boolean` Returns true if the specified BitVector has any bits set to true that are also set to true in this BitVector.
iterator	`fun iterator(): IntIterator`
length	`fun length(): Int` Returns the "logical size" of this bitset: the index of the highest set bit in the bitset plus one. Returns zero if the bitset contains no set bits.
or	`fun or(other: BitVector): Unit` Performs a logical OR of this bit set with the bit set argument. This bit set is modified so that a bit in it has the value `true` if and only if it either already had the value `true` or the corresponding bit in the bit set argument has the value `true`.
set	`fun set(index: Int): Unit` `operator fun set(index: Int, value: Boolean): Unit`
toString	`fun toString(): String`
unsafeClear	`fun unsafeClear(index: Int): Unit`
unsafeGet	`fun unsafeGet(index: Int): Boolean`
unsafeSet	`fun unsafeSet(index: Int): Unit` `fun unsafeSet(index: Int, value: Boolean): Unit`
xor	`fun xor(other: BitVector): Unit` Performs a logical XOR of this bit set with the bit set argument. This bit set is modified so that a bit in it has the value true if and only if one of the following statements holds:
