Method Detail

hasCells

public boolean hasCells()

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.

iterator

public java.util.Iterator<Cell> iterator()

Specified by:

iterator in interface java.lang.Iterable<Cell>

reverseIterator

dataSize

public int dataSize()

Description copied from class: ColumnData

The size of the data hold by this ColumnData.

Specified by:

dataSize in class ColumnData

Returns:

the size used by the data of this ColumnData.

unsharedHeapSizeExcludingData

validate

public void validate()

Description copied from class: ColumnData
