public BaseGridCell(GridCellValue<T> value)

Method Detail

getValue

public GridCellValue<T> getValue()

Description copied from interface: GridCell

Returns the value holder for the cell. It should be noted there is intentionally no "setter" as mutation of the value may require further mutation to other data within the grid. Therefore mutation of cell values is via the GridData interface to ensure the integrity of all data within the grid.

Specified by:

getValue in interface GridCell<T>

Returns:

setValue

protected void setValue(GridCellValue<T> value)

isMerged

public boolean isMerged()

Description copied from interface: GridCell

Returns whether the cell is in a merged state

Specified by:

isMerged in interface GridCell<T>

Returns:

true if merged

getMergedCellCount

public int getMergedCellCount()

Description copied from interface: GridCell

Returns the number of cells merged into this cell. For cells that are at the top of a merged block this should be the number of merged cells, including this cell. For cells that are not the top of a merged block but are contained in a merged block this should return zero. For non-merged cells this should return one.

Specified by:

getMergedCellCount in interface GridCell<T>

Returns:

The number of cells merged into this cell, or zero if part of a merged block or one if not merged.

isCollapsed

public boolean isCollapsed()

Description copied from interface: GridCell

Returns whether the cell is collapsed. For cells that are at the top of a collapsed block this should return false. For cells that are not the top of a collapsed block but are contained in a collapsed block this should return false.

Specified by:

isCollapsed in interface GridCell<T>

Returns:

true is collapsed.

collapse

public void collapse()

Description copied from interface: GridCell

Collapse the cell.

expand

public void expand()

Description copied from interface: GridCell

Expand the cell.

Specified by:

reset

public void reset()

Description copied from interface: GridCell

Reset the cell to a non-merged, non-collapsed state.

Specified by:

reset in interface GridCell<T>

getSelectionStrategy

public CellSelectionStrategy getSelectionStrategy()

Description copied from interface: GridCell

Returns the CellSelectionStrategy to handle selections of the cell.

Specified by:

Returns:

setSelectionStrategy

public void setSelectionStrategy(CellSelectionStrategy selectionStrategy)

Description copied from interface: GridCell

Sets the CellSelectionStrategy to handle selections of the cell.
