Package org.apache.druid.segment.data

Class SafeWritableBase

java.lang.Object
org.apache.druid.segment.data.SafeWritableBase
All Implemented Interfaces:
org.apache.datasketches.memory.BaseState
Direct Known Subclasses:
SafeWritableBuffer, SafeWritableMemory
public abstract class SafeWritableBase extends Object implements org.apache.datasketches.memory.BaseState
Base class for making a regular ByteBuffer look like a Memory or Buffer. All methods delegate directly to the ByteBuffer rather than using 'unsafe' reads.
