Package org.apache.druid.segment.data

Class SafeWritableBuffer

java.lang.Object
org.apache.druid.segment.data.SafeWritableBase
org.apache.druid.segment.data.SafeWritableBuffer
All Implemented Interfaces:
org.apache.datasketches.memory.BaseBuffer, org.apache.datasketches.memory.BaseState, org.apache.datasketches.memory.Buffer, org.apache.datasketches.memory.WritableBuffer
public class SafeWritableBuffer extends SafeWritableBase implements org.apache.datasketches.memory.WritableBuffer
Safety first! Don't trust something whose contents you locations to read and write stuff to, but need a Buffer or WritableBuffer? use this!

Delegates everything to an underlying ByteBuffer so all read and write operations will have bounds checks built in rather than using 'unsafe'.
