Constructor Detail

AbstractRowHideShowLayer

public AbstractRowHideShowLayer(IUniqueIndexLayer underlyingLayer)

Method Detail

handleLayerEvent

public void handleLayerEvent(ILayerEvent event)

Description copied from class: AbstractLayer

Handle layer event notification. Convert it to your context and propagate UP. If you override this method you MUST NOT FORGET to raise the event up the layer stack by calling super.fireLayerEvent(event) - unless you plan to eat the event yourself.

Specified by:

handleLayerEvent in interface ILayerListener

Overrides:

handleLayerEvent in class AbstractLayer

Parameters:

event - the event

getColumnPositionByIndex

public int getColumnPositionByIndex(int columnIndex)

Specified by:

getColumnPositionByIndex in interface IUniqueIndexLayer

getRowCount

public int getRowCount()

Specified by:

getRowCount in interface ILayer

Overrides:

getRowCount in class AbstractLayerTransform

Returns:

the number of rows in this coordinate model

getRowIndexByPosition

public int getRowIndexByPosition(int rowPosition)

Description copied from interface: ILayer

Gets the underlying non-transformed row index for the given row position.

Specified by:

getRowIndexByPosition in interface ILayer

Overrides:

getRowIndexByPosition in class AbstractLayerTransform

Parameters:

rowPosition - a row position relative to this coordinate model

Returns:

an underlying non-transformed row index, or -1 if the given row position does not exist within this coordinate system

getRowPositionByIndex

public int getRowPositionByIndex(int rowIndex)

Specified by:

getRowPositionByIndex in interface IUniqueIndexLayer

getRowPositionsByIndexes

public Collection<Integer> getRowPositionsByIndexes(Collection<Integer> rowIndexes)

localToUnderlyingRowPosition

public int localToUnderlyingRowPosition(int localRowPosition)

Specified by:

localToUnderlyingRowPosition in interface ILayer

Overrides:

localToUnderlyingRowPosition in class AbstractLayerTransform

underlyingToLocalRowPosition

public int underlyingToLocalRowPosition(ILayer sourceUnderlyingLayer,
                                        int underlyingRowPosition)

Specified by:

underlyingToLocalRowPosition in interface ILayer

Overrides:

underlyingToLocalRowPosition in class AbstractLayerTransform

underlyingToLocalRowPositions

public Collection<Range> underlyingToLocalRowPositions(ILayer sourceUnderlyingLayer,
                                                       Collection<Range> underlyingRowPositionRanges)

Specified by:

underlyingToLocalRowPositions in interface ILayer

Overrides:

underlyingToLocalRowPositions in class AbstractLayerTransform

getHeight

public int getHeight()

Description copied from interface: ILayer

Returns the total height in pixels of this layer.

Specified by:

getHeight in interface ILayer

Overrides:

getHeight in class AbstractLayerTransform

Returns:

the height of this layer

getRowPositionByY

public int getRowPositionByY(int y)

Description copied from interface: ILayer

Returns the row position that contains the given y coordinate.

Specified by:

getRowPositionByY in interface ILayer

Overrides:

getRowPositionByY in class AbstractLayerTransform

Parameters:

y - a vertical pixel location relative to the pixel boundary of this layer

Returns:

a row position relative to the associated coordinate system, or -1 if there is no row that contains y

getStartYOfRowPosition

public int getStartYOfRowPosition(int localRowPosition)

Description copied from interface: ILayer

Returns the y offset in pixels of the given row.

Specified by:

getStartYOfRowPosition in interface ILayer

Overrides:

getStartYOfRowPosition in class AbstractLayerTransform

Parameters:

localRowPosition - the row position in this layer

Returns:

the y offset of the row, or -1

isRowIndexHidden

public abstract boolean isRowIndexHidden(int rowIndex)

Will check if the row at the specified index is hidden or not. Checks this layer and also the sublayers for the visibility.

Parameters:

rowIndex - The row index of the row whose visibility state should be checked.

Returns:

true if the row at the specified index is hidden, false if it is visible.

getHiddenRowIndexes

public abstract Collection<Integer> getHiddenRowIndexes()

Will collect and return all indexes of the rows that are hidden in this layer. Note: It is not intended that it also collects the row indexes of underlying layers. This would cause issues on calculating positions as every layer is responsible for those calculations itself.

Returns:

Collection of all row indexes that are hidden in this layer.

invalidateCache

protected void invalidateCache()

Invalidate the cache to ensure that information is rebuild.

cacheVisibleRowIndexes

protected void cacheVisibleRowIndexes()
