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

Modifier and Type	Method and Description
default ColumnIndexSupplier	VirtualColumn.getIndexSupplier(String columnName, ColumnSelector columnSelector) Get the ColumnIndexSupplier for the specified virtual column, with the assistance of a ColumnSelector to allow reading things from segments.
ColumnIndexSupplier	VirtualColumns.getIndexSupplier(String columnName, ColumnSelector columnSelector) Get the ColumnIndexSupplier of the specified virtual column, with the assistance of a ColumnSelector to allow reading things from segments.
default ColumnValueSelector<?>	VirtualColumn.makeColumnValueSelector(String columnName, ColumnSelector columnSelector, ReadableOffset offset) Returns similar ColumnValueSelector object as returned by VirtualColumn.makeColumnValueSelector(String, ColumnSelectorFactory) except this method has full access to the underlying column and can potentially provide a more efficient implementation.
ColumnValueSelector<?>	VirtualColumns.makeColumnValueSelector(String columnName, ColumnSelector columnSelector, ReadableOffset offset) Try to create an optimized value selector directly from a ColumnSelector.
default DimensionSelector	VirtualColumn.makeDimensionSelector(DimensionSpec dimensionSpec, ColumnSelector columnSelector, ReadableOffset offset) Returns similar DimensionSelector object as returned by VirtualColumn.makeDimensionSelector(DimensionSpec, ColumnSelectorFactory) except this method has full access to the underlying column and can potentially provide a more efficient implementation.
DimensionSelector	VirtualColumns.makeDimensionSelector(DimensionSpec dimensionSpec, ColumnSelector columnSelector, ReadableOffset offset) Try to create an optimized dimension (string) selector directly from a ColumnSelector.
MultiValueDimensionVectorSelector	VirtualColumns.makeMultiValueDimensionVectorSelector(DimensionSpec dimensionSpec, ColumnSelector columnSelector, ReadableVectorOffset offset) Try to create an optimized multi value dimension (string) vector selector, directly from a ColumnSelector.
default MultiValueDimensionVectorSelector	VirtualColumn.makeMultiValueVectorDimensionSelector(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.
SingleValueDimensionVectorSelector	VirtualColumns.makeSingleValueDimensionVectorSelector(DimensionSpec dimensionSpec, ColumnSelector columnSelector, ReadableVectorOffset offset) Try to create an optimized single value dimension (string) vector selector, directly from a ColumnSelector.
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 VectorObjectSelector	VirtualColumn.makeVectorObjectSelector(String columnName, ColumnSelector columnSelector, ReadableVectorOffset offset) Returns similar VectorObjectSelector object as returned by VirtualColumn.makeVectorObjectSelector(String, VectorColumnSelectorFactory) except this method has full access to the underlying column and can potentially provide a more efficient implementation.
VectorObjectSelector	VirtualColumns.makeVectorObjectSelector(String columnName, ColumnSelector columnSelector, ReadableVectorOffset offset) Try to create an optimized vector object selector directly from a ColumnSelector.If this method returns null, callers should try to fallback to VirtualColumns.makeVectorObjectSelector(String, VectorColumnSelectorFactory) instead.
default VectorValueSelector	VirtualColumn.makeVectorValueSelector(String columnName, ColumnSelector columnSelector, ReadableVectorOffset offset) Returns similar VectorValueSelector object as returned by VirtualColumn.makeVectorValueSelector(String, VectorColumnSelectorFactory) except this method has full access to the underlying column and can potentially provide a more efficient implementation.
VectorValueSelector	VirtualColumns.makeVectorValueSelector(String columnName, ColumnSelector columnSelector, ReadableVectorOffset offset) Try to create an optimized vector value selector directly from a ColumnSelector.
