Package org.apache.iceberg.arrow.vectorized

Class IcebergArrowVectors.VarcharArrowVector

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable, java.lang.Iterable<org.apache.arrow.vector.ValueVector>, org.apache.arrow.vector.DensityAwareVector, org.apache.arrow.vector.FieldVector, org.apache.arrow.vector.ValueVector, org.apache.arrow.vector.VariableWidthVector, org.apache.arrow.vector.VectorDefinitionSetter
    Enclosing class:
    IcebergArrowVectors
    public static class IcebergArrowVectors.VarcharArrowVector
extends org.apache.arrow.vector.VarCharVector
    Extension of Arrow's @VarCharVector. The reason of having this implementation is to override the expensive BaseVariableWidthVector.isSet(int) method called by VarCharVector.get(int, NullableVarCharHolder)
