Class BitVector.Mutator

java.lang.Object

org.apache.arrow.vector.BaseValueVector.BaseMutator

org.apache.arrow.vector.BitVector.Mutator

All Implemented Interfaces:

ValueVector.Mutator

Enclosing class:

BitVector

public class BitVector.Mutator
extends BaseValueVector.BaseMutator

MutableBit implements a vector of bit-width values. Elements in the vector are accessed by position from the logical start of the vector. Values should be pushed onto the vector sequentially, but may be randomly accessed. NB: this class is automatically generated from ValueVectorTypes.tdd using FreeMarker.

void	set(int index, int value) Set the bit at the given index to the specified value.
void	setRangeToOne(int firstBitIndex, int count) set count bits to 1 in data starting at firstBitIndex
void	setSafe(int index, BitHolder holder)
void	setSafe(int index, int value)
void	setSafe(int index, NullableBitHolder holder)
void	setSafeToOne(int index)
void	setToOne(int index) Set the bit at the given index to 1.
void	setValueCount(int valueCount) Sets the number of values that is stored in this vector to the given value count.
