Method Detail

setData

public void setData(Map<Integer,ColProperty> columnProperties,
                    int[] rowIndices,
                    int[] columnIndices,
                    String[] values)

Replace the data of the table model by the given settings.

Parameters:

columnProperties - the properties of column

rowIndices - the row indices

columnIndices - the column indices

values - the values at the given row and column indices

getColumnProperties

SortedMap<Integer,ColProperty> getColumnProperties()

Returns a mapping of column index to the {ColProperty} of the column. The mapping must not exist for every column.

Returns:

a mapping of column index to the {ColProperty} of the column

getRowIndices

int[] getRowIndices()

see getValues();

Returns:

row indices populated with data

getColumnIndices

int[] getColumnIndices()

see getValues();

Returns:

column indices populated with data

getValues

String[] getValues()

Use in combination with getRowIndices and getColumnIndices. Together with this method you will three arrays which are a sparse representation of the tables data.

Returns:

the table data.
