Interface VectorColumnProcessorFactory<T>

All Known Implementing Classes:

GroupByVectorColumnProcessorFactory, VectorValueMatcherColumnProcessorFactory

public interface VectorColumnProcessorFactory<T>

Class that encapsulates knowledge about how to create vector column processors. Used by DimensionHandlerUtils.makeVectorProcessor(java.lang.String, org.apache.druid.segment.VectorColumnProcessorFactory<T>, org.apache.druid.segment.vector.VectorColumnSelectorFactory). Unlike ColumnProcessorFactory, this interface does not have a "defaultType" method. The default type is always implicitly STRING. It also does not have a "makeComplexProcessor" method; instead, complex-typed columns are fed into "makeSingleValueDimensionProcessor". This behavior may change in the future to better align with ColumnProcessorFactory.
