java.lang.Object
com.illumon.iris.db.v2.locations.FileDataBufferStore.StoredBufferMessage
All Implemented Interfaces:
Message
Enclosing class:
FileDataBufferStore
public static final class FileDataBufferStore.StoredBufferMessage extends Object implements Message

Message implementation to wrap a stored buffer and associated boundaries.

We fix the view's limit at construction time in order to ensure that we can return a constant length that accurately reflects the remaining bytes in a view.
