Method Detail

cellsCount

public int cellsCount()

getCell

public Cell<?> getCell(CellPath path)

getCellByIndex

public Cell<?> getCellByIndex(int idx)

complexDeletion

public DeletionTime complexDeletion()

The complex deletion time of the complex column.

The returned "complex deletion" is a deletion of all the cells of the column. For instance, for a collection, this correspond to a full collection deletion. Please note that this deletion says nothing about the individual cells of the complex column: there can be no complex deletion but some of the individual cells can be deleted.

Returns:

the complex deletion time for the column this is the data of or DeletionTime.LIVE if the column is not deleted.
