[jboss-user] [JBoss Cache: Core Edition] - Re: custom method to get size of nodes in cache evicts some

[jorgemoralespou_2]

But why adding a "Node visited event" is making the node to be evicted?

I have set up a 5 max lement FIFO EvictionPolicy. There is 5 nodes in cache. When I make a call to my custom getSize method, one of the nodes gets evicted, and size return 4.

I don't underastand this behaviour. Or is it counting the parent node as a node to be accounted for eviction?

I see this, where visiting a node is adding one of the subnodes to the eviction queue, and actually evicting it:
