SSTableNamesIterator

public SSTableNamesIterator(SSTableReader sstable,

                            DecoratedKey key,
                            java.util.SortedSet<java.nio.ByteBuffer> columns)

Method Detail

getKey

public DecoratedKey getKey()

Specified by:

getKey in interface IColumnIterator

Returns:

the current row key

getColumnFamily

public ColumnFamily getColumnFamily()

Description copied from interface: IColumnIterator

returns the CF of the column being iterated. Do not modify the returned CF; clone first. This is guaranteed to be non-null and that the returned CF have the correct metadata (markedForDeleteAt and localDeletionTime). The full CF is however only guaranteed to be available after a call to next() or hasNext().

Specified by:

getColumnFamily in interface IColumnIterator

computeNext

protected IColumn computeNext()

Specified by:

computeNext in class com.google.common.collect.AbstractIterator<IColumn>
