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.

                          org.apache.arrow.memory.BufferAllocator allocator)

Method Detail

isSet

public int isSet(int index)

Same as BaseVariableWidthVector.isNull(int).

Overrides:

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

Parameters:

index - position of element

Returns:

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