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.
