Class Alias

java.lang.Object

com.neocoretechs.rocksack.Alias

All Implemented Interfaces:

java.io.Serializable

public class Alias
extends java.lang.Object
implements java.io.Serializable

An alias is the means by which we can designate different databases when obtaining our ordered maps from the DatabaseManager.

Recall that in RockSack, a database is a tablespace directory that contains class instances which are RocksDB directories containing the serialized object instances. An alias allows us to define a macro that indicates the set of class instances that make up a database. For instance; If we have a tablespace directory of /home/db, then we can define a database as /home/db/test.

Instances of serialized classes will then be created under /home/db/testjava.lang.String, /home/db/testcom.yourpackage.yourclass subdirectories that contain the RocksDB SST and log files. etc.

If we define an alias as:
Alias testDb = new Alias("test");
we can then call:
DatabaseManager.setTableSpaceAlias(testDb, "/home/db/"), and thereafter refer to testDb when obtaining and subsequently operating on a BufferedMap or TransactionalMap, and the data for those maps will be placed under our /home/db/test... series of subdirectories.
