Constructor Detail

AppendedColumnRow

public AppendedColumnRow(DataRow baseRow,
                         DataCell... appendCell)

Creates new Row with baseRow providing the first cells and appendCell as last cells.

Parameters:

baseRow - Containing the first cells

appendCell - The last cells (to be appended).

AppendedColumnRow

public AppendedColumnRow(RowKey rowKey,
                         DataRow baseRow,
                         DataCell... appendCell)

Creates new Row with baseRow providing the first cells and appendCell as last cells.

Parameters:

rowKey - new row key for the resulting appended row

baseRow - Containing the first cells

appendCell - The last cells (to be appended).

AppendedColumnRow

public AppendedColumnRow(DataRow baseRow,
                         DataRow appendedRow,
                         boolean[] appendColumn)

Create a new row with the baseRow providing the first cells and appendedRow providing the following cells. Which cells from the second row should be appended is passed in appendColumn (true for adding the cells at the index, false for not adding it).

Parameters:

baseRow - row with the first cells

appendedRow - row with the cells to append

appendColumn - array with entries set to true, if the corresponding cells from the second row should be added

                         boolean[] appendColumn)

Create a new row with the baseRow providing the first cells and appendedRow providing the following cells. Which cells from the second row should be appended is passed in appendColumn (true for adding the cells at the index, false for not adding it).

Parameters:

rowKey - new row key for the resulting appended row

baseRow - row with the first cells

appendedRow - row with the cells to append

appendColumn - array with entries set to true, if the corresponding cells from the second row should be added

AppendedColumnRow

public AppendedColumnRow(RowKey rowKey,
