Method Details

instance

public static VectorValueMatcherColumnProcessorFactory instance()

makeSingleValueDimensionProcessor

public VectorValueMatcherFactory makeSingleValueDimensionProcessor(ColumnCapabilities capabilities,
 SingleValueDimensionVectorSelector selector)

Description copied from interface: VectorColumnProcessorFactory

Called only if TypeSignature.getType() is STRING and the underlying column always has a single value per row. Note that for STRING-typed columns where the dictionary does not exist or is not expected to be useful, VectorColumnProcessorFactory.makeObjectProcessor(org.apache.druid.segment.column.ColumnCapabilities, org.apache.druid.segment.vector.VectorObjectSelector) may be called instead. To handle all string inputs properly, processors must implement all three methods (single-value, multi-value, object).

Specified by:

makeSingleValueDimensionProcessor in interface VectorColumnProcessorFactory<VectorValueMatcherFactory>

makeMultiValueDimensionProcessor

public VectorValueMatcherFactory makeMultiValueDimensionProcessor(ColumnCapabilities capabilities,
 MultiValueDimensionVectorSelector selector)

Description copied from interface: VectorColumnProcessorFactory

Called only if TypeSignature.getType() is STRING and the underlying column may have multiple values per row. Note that for STRING-typed columns where the dictionary does not exist or is not expected to be useful, VectorColumnProcessorFactory.makeObjectProcessor(org.apache.druid.segment.column.ColumnCapabilities, org.apache.druid.segment.vector.VectorObjectSelector) may be called instead. To handle all string inputs properly, processors must implement all three methods (single-value, multi-value, object).

Specified by:

makeMultiValueDimensionProcessor in interface VectorColumnProcessorFactory<VectorValueMatcherFactory>

makeFloatProcessor

public VectorValueMatcherFactory makeFloatProcessor(ColumnCapabilities capabilities,
 VectorValueSelector selector)

Description copied from interface: VectorColumnProcessorFactory

Called when TypeSignature.getType() is FLOAT.

Specified by:

makeFloatProcessor in interface VectorColumnProcessorFactory<VectorValueMatcherFactory>

makeDoubleProcessor

public VectorValueMatcherFactory makeDoubleProcessor(ColumnCapabilities capabilities,
 VectorValueSelector selector)

Description copied from interface: VectorColumnProcessorFactory

Called when TypeSignature.getType() is DOUBLE.

Specified by:

makeDoubleProcessor in interface VectorColumnProcessorFactory<VectorValueMatcherFactory>

makeLongProcessor

public VectorValueMatcherFactory makeLongProcessor(ColumnCapabilities capabilities,
 VectorValueSelector selector)

Description copied from interface: VectorColumnProcessorFactory

Called when TypeSignature.getType() is LONG.

Specified by:

makeLongProcessor in interface VectorColumnProcessorFactory<VectorValueMatcherFactory>

makeArrayProcessor

public VectorValueMatcherFactory makeArrayProcessor(ColumnCapabilities capabilities,
 VectorObjectSelector selector)

Description copied from interface: VectorColumnProcessorFactory

Called when TypeSignature.getType() is ARRAY.

Specified by:

makeArrayProcessor in interface VectorColumnProcessorFactory<VectorValueMatcherFactory>

makeObjectProcessor

public VectorValueMatcherFactory makeObjectProcessor(ColumnCapabilities capabilities,
 VectorObjectSelector selector)

Description copied from interface: VectorColumnProcessorFactory

Called when TypeSignature.getType() is COMPLEX. May also be called for STRING typed columns in cases where the dictionary does not exist or is not expected to be useful.

Specified by:

makeObjectProcessor in interface VectorColumnProcessorFactory<VectorValueMatcherFactory>
