Class BytesMapEventListener

java.lang.Object

net.openhft.chronicle.map.BytesMapEventListener

All Implemented Interfaces:

Serializable

public abstract class BytesMapEventListener
extends Object
implements Serializable

• Methods must not update entry state (position, limit).
• Methods must not update entry bytes, except in metadata area
• From metaDataPos offset metadata area starts in the given entry, listener should be itself aware of it's length (see ChronicleMapBuilder.metaDataBytes(int)).
• From keyPos offset key area in the given entry, serialized key size (using ChronicleMapBuilder.keySizeMarshaller(SizeMarshaller)), directly followed by the serialized key itself.
• From valuePos offset value area in the given entry, serialized value size (using ChronicleMapBuilder.keySizeMarshaller(SizeMarshaller)), then (optionally) alignment (see ChronicleMapBuilder.entryAndValueAlignment(Alignment) ), followed by the serialized value itself.

There are helper methods ChronicleMap.readKey(Bytes, long) and ChronicleMap.readValue(Bytes, long) that help to deal with this.
