Class BitVector.Mutator

java.lang.Object

org.apache.drill.exec.vector.BaseValueVector.BaseMutator

org.apache.drill.exec.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.

Method Summary

void	set(int index, int value) Set the bit at the given index to the specified value.
void	setSafe(int index, org.apache.drill.exec.expr.holders.BitHolder holder)
void	setSafe(int index, int value)
void	setSafe(int index, org.apache.drill.exec.expr.holders.NullableBitHolder holder)
void	setValueCount(int valueCount) Sets the number of values that is stored in this vector to the given value count.

Method Detail

set

public final void set(int index,
                      int value)

Set the bit at the given index to the specified value.

Parameters:

index - position of the bit to set

value - value to set (either 1 or 0)

set

public final void set(int index,
                      org.apache.drill.exec.expr.holders.BitHolder holder)

setSafe

public void setSafe(int index,
                    int value)

setSafe

public void setSafe(int index,
                    org.apache.drill.exec.expr.holders.BitHolder holder)

setSafe

public void setSafe(int index,
                    org.apache.drill.exec.expr.holders.NullableBitHolder holder)

setValueCount

public final void setValueCount(int valueCount)

Description copied from interface: ValueVector.Mutator

Sets the number of values that is stored in this vector to the given value count. WARNING! Once the valueCount is set, the vector should be considered immutable.

Parameters:

valueCount - value count to set.

generateTestData

public final void generateTestData(int values)

Specified by:

generateTestData in interface ValueVector.Mutator

Overrides:

generateTestData in class BaseValueVector.BaseMutator
