Package org.apache.iceberg.arrow.vectorized

Class IcebergArrowVectors.DecimalArrowVector

  • 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).
