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.
