Uses of SingleValueDimensionVectorSelector in org.apache.druid.query.dimension

Methods in org.apache.druid.query.dimension that return SingleValueDimensionVectorSelector

Modifier and Type	Method and Description
default SingleValueDimensionVectorSelector	DimensionSpec.decorate(SingleValueDimensionVectorSelector selector) Vectorized analog of DimensionSpec.decorate(DimensionSelector) for SingleValueDimensionVectorSelector, most likely produced with VectorColumnSelectorFactory.makeSingleValueDimensionSelector(DimensionSpec) Decoration allows a DimensionSpec to customize the behavior of the underlying selector, for example transforming or filtering values.
SingleValueDimensionVectorSelector	DefaultDimensionSpec.decorate(SingleValueDimensionVectorSelector selector)

Methods in org.apache.druid.query.dimension with parameters of type SingleValueDimensionVectorSelector

Modifier and Type	Method and Description
default SingleValueDimensionVectorSelector	DimensionSpec.decorate(SingleValueDimensionVectorSelector selector) Vectorized analog of DimensionSpec.decorate(DimensionSelector) for SingleValueDimensionVectorSelector, most likely produced with VectorColumnSelectorFactory.makeSingleValueDimensionSelector(DimensionSpec) Decoration allows a DimensionSpec to customize the behavior of the underlying selector, for example transforming or filtering values.
SingleValueDimensionVectorSelector	DefaultDimensionSpec.decorate(SingleValueDimensionVectorSelector selector)

Uses of SingleValueDimensionVectorSelector in org.apache.druid.query.filter.vector

Uses of SingleValueDimensionVectorSelector in org.apache.druid.segment

Methods in org.apache.druid.segment that return SingleValueDimensionVectorSelector

Modifier and Type	Method and Description
SingleValueDimensionVectorSelector	VirtualColumns.makeSingleValueDimensionVectorSelector(DimensionSpec dimensionSpec, ColumnSelector columnSelector, ReadableVectorOffset offset) Try to create an optimized single value dimension (string) vector selector, directly from a ColumnSelector.
SingleValueDimensionVectorSelector	VirtualColumns.makeSingleValueDimensionVectorSelector(DimensionSpec dimensionSpec, VectorColumnSelectorFactory factory) Create a single value dimension vector (string) selector.
default SingleValueDimensionVectorSelector	VirtualColumn.makeSingleValueVectorDimensionSelector(DimensionSpec dimensionSpec, ColumnSelector columnSelector, ReadableVectorOffset offset) Returns similar SingleValueDimensionVectorSelector object as returned by VirtualColumn.makeSingleValueVectorDimensionSelector(DimensionSpec, ColumnSelector, ReadableVectorOffset) except this method has full access to the underlying column and can potentially provide a more efficient implementation.
default SingleValueDimensionVectorSelector	VirtualColumn.makeSingleValueVectorDimensionSelector(DimensionSpec dimensionSpec, VectorColumnSelectorFactory factory) Build a SingleValueDimensionVectorSelector corresponding to this virtual column.

Methods in org.apache.druid.segment with parameters of type SingleValueDimensionVectorSelector

Modifier and Type	Method and Description
T	VectorColumnProcessorFactory.makeSingleValueDimensionProcessor(ColumnCapabilities capabilities, SingleValueDimensionVectorSelector selector) Called only if ColumnCapabilities.getType() is STRING and the underlying column always has a single value per row.
