Class IcebergArrowVectors.DecimalArrowVector

java.lang.Object

org.apache.arrow.vector.BaseValueVector

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable, java.lang.Iterable<org.apache.arrow.vector.ValueVector>, org.apache.arrow.vector.FieldVector, org.apache.arrow.vector.FixedWidthVector, org.apache.arrow.vector.ValueVector, org.apache.arrow.vector.VectorDefinitionSetter

Enclosing class:

IcebergArrowVectors

public static class IcebergArrowVectors.DecimalArrowVector
extends org.apache.arrow.vector.DecimalVector

Extension of Arrow's @DecimalVector. The whole reason of having this implementation is to override the expensive BaseFixedWidthVector.isSet(int) method used by DecimalVector.getObject(int).

Constructor Detail

DecimalArrowVector

public DecimalArrowVector(java.lang.String name,
                          org.apache.arrow.memory.BufferAllocator allocator,
                          int precision,
                          int scale)

Method Detail

isSet

public int isSet(int index)

Same as BaseFixedWidthVector.isNull(int).

Overrides:

isSet in class org.apache.arrow.vector.BaseFixedWidthVector

Parameters:

index - position of element

Returns:

1 if element at given index is not null, 0 otherwise

setNullabilityHolder

public void setNullabilityHolder(NullabilityHolder nullabilityHolder)
