Package org.apache.drill.exec.vector

Class Decimal38DenseVector.Mutator

java.lang.Object

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

org.apache.drill.exec.vector.Decimal38DenseVector.Mutator

All Implemented Interfaces:

ValueVector.Mutator

Enclosing class:

Decimal38DenseVector

public final class Decimal38DenseVector.Mutator
extends BaseValueVector.BaseMutator

Decimal38Dense.Mutator implements a mutable vector of fixed 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.

• The width of each element is Decimal38DenseVector.VALUE_WIDTH (= 16) byte(s).
• The equivalent Java primitive is 'DrillBuf'

NB: this class is automatically generated from ValueVectorTypes.tdd using FreeMarker.

Method Details

set

public void set(int index,
 DrillBuf value)

Set the element at the given index to the given value. Note that widths smaller than 32 bits are handled by the DrillBuf interface.

Parameters:

index - position of the bit to set

value - value to set

setSafe

public void setSafe(int index,
 DrillBuf value)

setSafe

public void setSafe(int index,
 int start,
 DrillBuf buffer)

set

public void set(int index,
 Decimal38DenseHolder holder)

setSafe

public void setSafe(int index,
 Decimal38DenseHolder holder)

setSafe

public void setSafe(int index,
 NullableDecimal38DenseHolder holder)

set

public void set(int index,
 int start,
 DrillBuf buffer)

generateTestData

public void generateTestData(int count)

Specified by:

generateTestData in interface ValueVector.Mutator

Overrides:

generateTestData in class BaseValueVector.BaseMutator

setValueCount

public 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.
