List of bitCount() Examples

Examples of bitCount()

cc.redberry.core.utils.BitArray.bitCount()
Returns the number of 1 bits. @return number of 1 bits
cc.redberry.core.utils.ByteBackedBitArray.bitCount()
java.math.BigInteger.bitCount()
Returns the number of bits in the two's complement representation of this BigInteger that differ from its sign bit. This method is useful when implementing bit-vector style sets atop BigIntegers. @return number of bits in the two's complement representationof this BigInteger that differ from its sign bit.
org.jenetics.BitChromosome.bitCount()
Returns the number of bits set to true in this {@code BitChromosome}. @return the number of bits set to true in this {@code BitChromosome}
