Examples of org.kiji.schema.KijiRowData.containsCell()

org.kiji.schema.KijiRowData.containsCell()
Determines whether a particular column has data in this row with the specified timestamp. @param family Column family of the column to check for. @param qualifier Column qualifier of the column to check for. @param timestamp Timestamp of the value to check for. @return Whether the specified column has data in this row with the specified timestamp.

    rowData = mReader.get(mEntityId, dataRequest);
