Interface SingleValueDimensionVectorSelector

All Superinterfaces:

DimensionDictionarySelector, VectorSizeInspector

All Known Implementing Classes:

NilVectorSelector, SingleStringInputDeferredEvaluationExpressionDimensionVectorSelector, StringUtf8DictionaryEncodedColumn.StringSingleValueDimensionVectorSelector

public interface SingleValueDimensionVectorSelector
extends DimensionDictionarySelector, VectorSizeInspector

Vectorized selector for a singly-valued string-typed column. Unlike the non-vectorized version, this is done as a separate interface, which is useful since it allows "getRowVector" to be a primitive int array.

Method Details

getRowVector

int[] getRowVector()

Get the current vector. The array will be reused, so it is not a good idea to retain a reference to it.
