Class ColumnSortedMap
java.lang.Object
org.apache.cassandra.io.util.ColumnSortedMap
- All Implemented Interfaces:
- java.util.Map<java.nio.ByteBuffer,IColumn>, java.util.SortedMap<java.nio.ByteBuffer,IColumn>
public class ColumnSortedMap
- extends java.lang.Object
- implements java.util.SortedMap<java.nio.ByteBuffer,IColumn>
Facade over a DataInput that contains IColumns in sorted order.
We use this because passing a SortedMap to the ConcurrentSkipListMap constructor is the only way
to invoke its private buildFromSorted method and avoid worst-case behavior of CSLM.put.
