Class RegionFactory

java.lang.Object
  com.gemstone.gemfire.cache.RegionFactory

public class RegionFactory
extends Object

RegionFactory is a factory that encapsulates the following four steps to simplify Region creation.

1. Connecting to a DistributedSystem
2. Creation of a Cache
3. Instantiation and configuration of RegionAttributes using a AttributesFactory
4. Creation of a Region using the Cache

RegionFactory simplifies these steps into one class and potentially one step:

 final Region portfolios = new RegionFactory().setScope(Scope.DISTRIBUTED_ACK)
                           .setCacheLoader(new PortfolioDBLoader())
                           .setValueConstraint(Portfolio.class).setKeyConstraint(Integer.class)
                           .create("Portfolios");

 

or if you already have a Region that has many simimlar attributes to the one you would like to create, you can do this:

      final Region persistentPortfolios = new RegionFactory(portfolios.getAttributes())
                                          .setDiskDirs(new File[] {new File("/stor1/port1.persist"),
                                                                   new File("/stor2/port2.persis")})
                                          .setDiskWriteAttributes(new new DiskWriteAttributes())
                                          .create("Portfolios");
 

or you can refer to a collection of attributes already defined in a cache.xml file:

 final Region lruToDiskPortfolios = new RegionFactory("persistent")
                                    .create("Portfolios");
 

Where persistent is defined in a cache.xml file in this way:

      <region-attributes id="persistent" persist-backup="true" mirror-type="keys-values">
        <disk-write-attributes>
           <asynchronous-writes bytes-threshold="1000" time-interval="30"/>
         </disk-write-attributes>
         <eviction-attributes>
            <lru-entry-count maximum="1000" action="overflow-to-disk"/>
         </eviction-attributes>
      </region-attributes>
