How could I create a new Region programmatically?

[sancheski]

Hi

I am trying to set an eviction policy to a region that does not exit yet. I know how to set an eviction policy to a region that already exists, but my problem comes up when I have to create a new region. How could I do it?

I am getting the region manager instance and after seeing that the region I want to configure does not exist, I try to create a region using createRegion(Fqn fqn, EvictionPolicy policy, EvictionConfiguration config).

Does anyone know how to do it?

Thanks in advance

I think I found the solution, perhaps it is gonna be usefull for someone.

The code below could be used as an example:

//getting the cache's eviction RegionManager
RegionManager regionMgr = cache.getEvictionRegionManager();

//Creating your own EvictionConfiguration
FIFOConfiguration config = new FIFOConfiguration();
((FIFOConfiguration) config).setMaxNodes(10);

//New instance of an EvictionPolicy
FIFOEviction eviction = new FIFOPolicy();
//Configure eviction policy in the cache instance
eviction.configure(cache);
//finally, create the region
regionMgr.createRegion("/foo/com", eviction, config);

What I was missing was the eviction configuration in the cache instance (eviction.configure(cache);) so I got a NullPointerException when the Timer threads did periodic node clean up by running the eviction policy.
