- Method Detail
  - load
```
void load()
```
    Load - perform some kinds of search for JenaSubsystemLifecycle implementations. This is called once in the initialization process.
  - add
```
void add(JenaSubsystemLifecycle module)
```
    Add to the collection.
  - isRegistered
```
boolean isRegistered(JenaSubsystemLifecycle module)
```
    check whether registered
  - remove
```
void remove(JenaSubsystemLifecycle module)
```
    Remove from the collection.
  - size
```
int size()
```
  - isEmpty
```
boolean isEmpty()
```
  - snapshot
```
java.util.List<JenaSubsystemLifecycle> snapshot()
```
    Return the registered items in a copied list. The list is detached from the registry and the caller can mutate it. There is no specific ordering requirement.
