Class BasicTSKeyConverter

java.lang.Object

com.fasterxml.clustermate.api.EntryKeyConverter<BasicTSKey>

com.fasterxml.transistore.basic.BasicTSKeyConverter

public class BasicTSKeyConverter
extends com.fasterxml.clustermate.api.EntryKeyConverter<BasicTSKey>

Default EntryKeyConverter used with Basic TransiStore types.

In addition class implements encoding and decoding of the entry keys (of type BasicTSKey): uses BasicTSConstants.TS_QUERY_PARAM_PARTITION_ID in addition to path (which is regular filename).
