All Implemented Interfaces:

Serializable
```
public class ContentViewCache
extends Object
implements Serializable
```
Cache for content views, handling cache keys set on content views.

- Method Detail
  - add
```
public void add(ContentView cView)
```
    Add given content view to the cache, resolving its cache key and initializing it with its cache size.
    Since 5.7, content views with a cache size <= 0 will be cached anyhow to handle selections, and rendering is in charge of forcing cache reset when re-displaying the page.
  - get
```
public ContentView get(String name)
```
    Returns cached content view with given name, or null if not found.
  - refresh
```
public void refresh(String contentViewName,
                    boolean rewind)
```
    Refresh page providers for content views in the cache with given name.refreshEventToContentViewName
    Other contextual information set on the content view and the page provider will be kept.
  - resetPageProvider
```
public void resetPageProvider(String contentViewName)
```
    Resets page providers for content views in the cache with given name.
    Other contextual information set on the content view will be kept.
  - resetPageProviderAggregates
```
public void resetPageProviderAggregates(String contentViewName)
```
    Resets page providers aggregates.

  - refreshOnEvent
```
public void refreshOnEvent(String eventName)
```
    Refresh page providers for content views having declared given event as a refresh event.

```
public void resetPageProviderOnEvent(String eventName)
```
    Resets page providers for content views having declared given event as a reset event.
    Other contextual information set on the content view will be kept.
