Constructor Detail

GenericObjectTable

public GenericObjectTable()

Creates a new object table.

GenericObjectTable

public GenericObjectTable(int increment)

Creates a new table.

Parameters:

increment - the row and column size increment.

                  int colIncrement)

Creates a new table.

Parameters:

rowIncrement - the row size increment.

colIncrement - the column size increment.

Method Detail

getObject

public T getObject(int row,
          int column)

Returns the object from a particular cell in the table. Returns null, if there is no object at the given position.

Note: throws IndexOutOfBoundsException if row or column is negative.

Parameters:

row - the row index (zero-based).

column - the column index (zero-based).

Returns:

The object.

setObject

public void setObject(int row,
             int column,
             T object)

Sets the object for a cell in the table. The table is expanded if necessary.

Parameters:

row - the row index (zero-based).

column - the column index (zero-based).

object - the object.

copyColumn

public void copyColumn(int oldColumn,
              int newColumn)

Copys the contents of the old column to the new column.

Parameters:

oldColumn - the index of the old (source) column

newColumn - the index of the new column

copyRow

public void copyRow(int oldRow,
           int newRow)

Copys the contents of the old row to the new row. This uses raw access to the data and is remarkably faster than manual copying.

Parameters:

oldRow - the index of the old row

newRow - the index of the new row
