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 Details

    • 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, BitHolder holder)

    • setSafe

      public void setSafe(int index, int value)

    • setSafe

      public void setSafe(int index, BitHolder holder)

    • setSafe

      public void setSafe(int index, 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.
