Field Summary

static int	ADDED howChanged constant which indicates that cell vectors have been added to the table.
static int	ALL_REPLACED howChanged constant which indicates that an entire set of cell vectors has been completely replaced by a new set.
static int	CELLS howChanged constant which indicates that a cell vector's cells have changed.
static int	CLASS howChanged constant which indicates that a cell vector's class has changed.
int	count The number of changed cell vectors.
static int	DEFAULT_VALUE howChanged constant which indicates that a cell vector's default value has changed.
int	howChanged Indicates how the cell vectors have changed.
int	index The one-based identifier of the first (or only) changed cell vector.
static int	REMOVED howChanged constant which indicates that cell vectors have been removed from the table.

Constructor Summary

CellVectorChangedEvent(java.lang.Object source)
Constructs an event to indicate that an entire set of cell vectors has been completely replaced by a new set.

CellVectorChangedEvent(java.lang.Object source, int index, int count, int howChanged)
Constructs an event to signal a change to a range of cell vectors.

Method Summary

java.lang.String

toString()

Field Detail

ADDED

public static final int ADDED

howChanged constant which indicates that cell vectors have been added to the table. index refers to the newly added cell vector. The cell vector formerly associated with index (if any, could be appending) is now associated with index+count.

howChanged, Constant Field Values

REMOVED

public static final int REMOVED

howChanged constant which indicates that cell vectors have been removed from the table. index refers to the removed cell vector. The cell vector formerly associated with index+count (if any) is now associated with index.

See Also:

howChanged, Constant Field Values

ALL_REPLACED

public static final int ALL_REPLACED

howChanged constant which indicates that an entire set of cell vectors has been completely replaced by a new set. For example, a dataset with a new where clause applied would have a completely new set of rows, but the same columns. index and count are ignored when this constant is used.

howChanged, Constant Field Values

CELLS

public static final int CELLS

howChanged constant which indicates that a cell vector's cells have changed.

See Also:

howChanged, Constant Field Values

CLASS

public static final int CLASS

howChanged constant which indicates that a cell vector's class has changed.

See Also:

howChanged, Constant Field Values

DEFAULT_VALUE

public static final int DEFAULT_VALUE

howChanged constant which indicates that a cell vector's default value has changed.

See Also:

howChanged, Constant Field Values

index

public final int index

The one-based identifier of the first (or only) changed cell vector.

count

public final int count

The number of changed cell vectors.

howChanged

public final int howChanged

Indicates how the cell vectors have changed.

Constructor Detail

CellVectorChangedEvent

public CellVectorChangedEvent(java.lang.Object source,
                              int index,
                              int count,
                              int howChanged)

Constructs an event to signal a change to a range of cell vectors. Cell vectors index through index+count-1 will be considered changed.

Parameters:

source - The table model whose cell vector(s) has changed.

index - The one-based identifier of the first (or only) changed cell vector.

count - The number of changed cell vectors.

howChanged - Indicates how the cell vectors have changed.

CellVectorChangedEvent

public CellVectorChangedEvent(java.lang.Object source)

Constructs an event to indicate that an entire set of cell vectors has been completely replaced by a new set. For example, a dataset with a new where clause applied would have a completely new set of rows, but the same columns.

Parameters:

source - The table model whose cell vectors have changed.
