[jboss-jira] [JBoss JIRA] Updated: (JBCACHE-893) Create a pluggable PojoCache Collection class implementation

Create a pluggable PojoCache Collection class implementation ------------------------------------------------------------ Key: JBCACHE-893 URL: http://jira.jboss.com/jira/browse/JBCACHE-893 Project: JBoss Cache Issue Type: Feature Request Security Level: Public(Everyone can see) Components: PojoCache Reporter: Ben Wang Assigned To: Jason T. Greene Fix For: PojoCache Original Estimate: 1 week Remaining Estimate: 1 week Currently PojoCache only supports a single flavor of Collection classes, e.g., HashMap, HashSet, and ArrayList. To fully support different flavor of Collection implementation, we can either: 1. Enable array interception from Jboss Aop such that we can instrument all Collection implementation classes (including java.util.*). But JBoss Aop currently doesn't support it yet, and issues of instrumenting the Sun system classes also is problematic. 2. Create a pluggable architecture for different flavor of Collection implementation. I think Option #2 is more realistic now. What I propose is this: 1. Will need to implement a specific flavor of collection interceptor and cache impl. E.g., in the case of List, it will be CachedListInterceptor and CachedListImpl. 2. Register the specific impl and the corresponding Collection class name to a registry During runtime, when we encounter Collection classes, we will check the registry first to see which interceptor (and the corresponding cache impl) that we will use for this case. Performance impact should be minimal since this is needed only for attach phase.
