Constructor Detail

BinnerColumnFactory

BinnerColumnFactory(int columnIdx,
                    BinnerColumnFactory.Bin[] bins,
                    String name,
                    boolean append)

Deprecated.

A binned column created by name and a number of bins. The new, binned column is either append or replaced in the current table.

Parameters:

columnIdx - the column index to bin

name - the new binned column name

bins - a set of bins

append - append or replace column

Method Detail

getColumnIndex

int getColumnIndex()

Deprecated.

Returns:

the column index to bin

isAppendedColumn

boolean isAppendedColumn()

Deprecated.

Returns:

if this bin is appended to the table

getColumnSpec

DataColumnSpec getColumnSpec()

Deprecated.

Returns:

the column name to append

getNrBins

int getNrBins()

Deprecated.

Returns:

number of bins

getBin

BinnerColumnFactory.Bin getBin(int index)

Deprecated.

Return Bin for index.

Parameters:

index - for this index

Returns:

the assigned bin

apply

DataCell apply(DataCell cell)

Deprecated.

Apply a value to this bining trying to cover it at all available Bins.

Parameters:

cell - the value to cover

Returns:

the bin's name as DataCell which cover's this value

getCells

public DataCell[] getCells(DataRow row)

Deprecated.

Get the new cells for a given row. These cells are incorporated into the existing row. The way it is done is defined through the ColumnRearranger using this object.

Specified by:

getCells in interface CellFactory

Parameters:

row - The row of interest.

Returns:

The new cells to that row.

getColumnSpecs

public DataColumnSpec[] getColumnSpecs()

Deprecated.

The column specs for the cells that are generated in the getCells() method. This method is only called once, there is no need to cache the return value. The length of the returned array must match the length of the array returned by the getCells(DataRow) method and also the types must match, i.e. the type of the respective DataColumnSpec must be of the same type or a super type of the cell as returned by getCells(DataRow).

Specified by:

getColumnSpecs in interface CellFactory

Returns:

The specs to the newly created cells.

setProgress

public void setProgress(int curRowNr,
                        int rowCount,
                        RowKey lastKey,
                        ExecutionMonitor exec)

Deprecated.

This method is called when a row has been processed. It allows the implementor to set progress in the execution monitor and also some meaningful progress message.

Note, you don't need to check exec.checkCanceled() in the implementation as this is done in the calling class.

Specified by:

setProgress in interface CellFactory

Parameters:

curRowNr - The number of the row just processed

rowCount - The total number of rows.

lastKey - The row's key.

exec - The execution monitor to report progress to.
