Package org.apache.cassandra.utils.bytecomparable

Class ByteSource.Separator

java.lang.Object

org.apache.cassandra.utils.bytecomparable.ByteSource.Separator

All Implemented Interfaces:

ByteSource

Enclosing interface:

ByteSource

public static class ByteSource.Separator
extends Object
implements ByteSource

Construct the shortest common prefix of prevMax and currMin that separates those two byte streams. If useCurr == true the last byte of the returned stream comes from currMin and is the first byte which is greater than byte on the corresponding position of prevMax. Otherwise, the last byte of the returned stream comes from prevMax and is incremented by one, still guaranteeing that it is <= than the byte on the corresponding position of currMin.
