Class DecimalVector.Mutator

java.lang.Object

org.apache.arrow.vector.BaseValueVector.BaseMutator

org.apache.arrow.vector.DecimalVector.Mutator

All Implemented Interfaces:

ValueVector.Mutator

Enclosing class:

DecimalVector

public final class DecimalVector.Mutator
extends BaseValueVector.BaseMutator

Decimal.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 16 byte(s) The equivalent Java primitive is 'ArrowBuf' NB: this class is automatically generated from ValueVectorTypes.tdd using FreeMarker.

Method Detail

set

public void set(int index,
       ArrowBuf value)

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

Parameters:

index - position of the bit to set

value - value to set

setSafe

public void setSafe(int index,
           ArrowBuf value)

set

public void set(int index,
       DecimalHolder holder)

setSafe

public void setSafe(int index,
           NullableDecimalHolder holder)

setSafe

public void setSafe(int index,
           DecimalHolder holder)

setSafe

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

set

public void set(int index,
       int start,
       ArrowBuf 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
