Constructor Detail

AndElementOperator

protected AndElementOperator(OperatorData operatorData,
                             GlobalSettings globalSettings,
                             OperatorColumnSettings opColSettings)

Deprecated.

Constructor for class AndElementOperator.

Parameters:

operatorData - the operator data

globalSettings - the global settings

opColSettings - the operator column specific settings

AndElementOperator

public AndElementOperator(GlobalSettings globalSettings,
                          OperatorColumnSettings opColSettings)

Deprecated.

Constructor for class AndElementOperator.

Parameters:

globalSettings - the global settings

opColSettings - the operator column specific settings

Method Detail

createInstance

public AggregationOperator createInstance(GlobalSettings globalSettings,
                                          OperatorColumnSettings opColSettings)

Deprecated.

Creates a new instance of this operator. A new instance is created for each column. Remember to copy all operator specific settings when creating a new instance!

Specified by:

createInstance in class AggregationOperator

Parameters:

globalSettings - the global settings

opColSettings - the operator column specific settings

Returns:

a new instance of this operator

getDataType

protected DataType getDataType(DataType origType)

Deprecated.

Specified by:

getDataType in class AggregationOperator

Parameters:

origType - the DataType of the original column to aggregate

Returns:

the DataType of the aggregation result

computeInternal

protected boolean computeInternal(DataCell cell)

Deprecated.

If the AggregationOperator implementation also requires the DataRow during computation override the AggregationOperator.computeInternal(DataRow, DataCell) method. Even if the AggregationOperator.computeInternal(DataRow, DataCell) method is implemented this method still might be called by previous implementations prior version 2.6 and should compute a reasonable result.

Specified by:

computeInternal in class AggregationOperator

Parameters:

cell - the DataCell to consider during computing the cell can't be null but can be a missing cell DataCell.isMissing() if the AggregationOperator.inclMissingCells() option is set to true.

Returns:

true if this column should be skipped in further calculations

See Also:

AggregationOperator.computeInternal(DataRow, DataCell)

getValues

protected Collection<DataCell> getValues()

Deprecated.

Returns:

the values that have been collected so far as an unmodifiable collection

getResultInternal

protected DataCell getResultInternal()

Deprecated.

Specified by:

getResultInternal in class AggregationOperator

Returns:

the result DataCell

resetInternal

protected void resetInternal()

Deprecated.

Should reset the operator to the start values.

Specified by:

resetInternal in class AggregationOperator

getDescription

public String getDescription()

Deprecated.

Returns:

the description for this function
