Detailed Description

combine some of the rows of a table

Collapses the rows of the input table so that one particular column (the IndexColumn) does not contain any duplicate values. Thus the output table will have the same columns as the input table, but potentially fewer rows. One example use of this class would be to generate a summary table from a table of observations. When two or more rows of the input table share a value in the IndexColumn, the values from these rows will be combined on a column-by-column basis. By default, such numerical values will be reduced to their mean, and non-numerical values will be reduced to their mode. This default behavior can be changed by calling SetNumericalReductionMethod() or SetNonNumericalReductionMethod(). You can also specify the reduction method to use for a particular column by calling SetReductionMethodForColumn().

virtual int vtkReduceTable::IsA ( const char * name )

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

void vtkReduceTable::PrintSelf	(	ostream &	os,

virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkTableAlgorithm.

virtual vtkIdType vtkReduceTable::GetIndexColumn ( )

virtual

Get/Set the column that will be used to reduce the input table. Any rows sharing a value in this column will be collapsed into a single row in the output table.

virtual void vtkReduceTable::SetIndexColumn ( vtkIdType )

virtual

Get/Set the column that will be used to reduce the input table. Any rows sharing a value in this column will be collapsed into a single row in the output table.

virtual int vtkReduceTable::GetNumericalReductionMethod ( )

virtual

Get/Set the method that should be used to combine numerical values.

virtual void vtkReduceTable::SetNumericalReductionMethod ( int )

virtual

Get/Set the method that should be used to combine numerical values.

virtual int vtkReduceTable::GetNonNumericalReductionMethod ( )

virtual

Get/Set the method that should be used to combine non-numerical values.

virtual void vtkReduceTable::SetNonNumericalReductionMethod ( int )

virtual

Get/Set the method that should be used to combine non-numerical values.

int vtkReduceTable::GetReductionMethodForColumn ( vtkIdType col )

Get the method that should be used to combine the values within the specified column. Returns -1 if no method has been set for this particular column.

void vtkReduceTable::SetReductionMethodForColumn	(	vtkIdType	col,

This is called by the superclass. This is the method you should override.

Reimplemented from vtkTableAlgorithm.

void vtkReduceTable::InitializeOutputTable	(	vtkTable *	input,

	)

protected

Initialize the output table to have the same types of columns as the input table, but no rows.

void vtkReduceTable::AccumulateIndexValues ( vtkTable * input )

protected

Find the distinct values in the input table's index column. This function also populates the mapping of new row IDs to old row IDs.

Populate the index column of the output table.

void vtkReduceTable::PopulateDataColumn	(	vtkTable *	input,
		vtkTable *	output,
		vtkIdType	col
	)

protected

Populate a non-index column of the output table. This involves potentially combining multiple values from the input table into a single value for the output table.

void vtkReduceTable::ReduceValuesToMean	(	vtkTable *	input,
		vtkTable *	output,
		vtkIdType	row,
		vtkIdType	col,
		std::vector< vtkIdType >	oldRows
