Class Name2Addr.Entry

java.lang.Object

com.bigdata.journal.Name2Addr.Entry

Enclosing class:

Name2Addr

public static class Name2Addr.Entry
extends Object

An entry in the persistent index.

The Name2Addr.Entry reports the name of the index, its checkpointAddr, and the commitTime when it was last updated. If you want to know more about the index, then you need to open it.

Do NOT open the index directly from the checkpointAddr. That will circumvent the canonical mapping imposed by the IIndexManager on the open indices for a given name and commit time. Instead, just ask the IIndexManager to open the index having the specified name as of the desired commit time.
