All Known Implementing Classes:

PageClassLoaderContextManagerImpl
```
public interface PageClassLoaderContextManager
```
Service that creates PageClassLoaderContext instances (except the root one) when a class in a controlled page is first used in the Tapestry page pool. Existing contexts may be reused for a given class, specially when in production mode.

Since:

5.8.3

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`clear()`	Clears any state held by this manager.
`void`	`clear(java.lang.String className)`	Removes one specific class from this manager, invalidating the context where it is.
`PageClassLoaderContext`	`get(java.lang.String className)`	Processes a class, given its class name and the root context.
`java.lang.Class<?>`	`getClassInstance(java.lang.Class<?> clasz, java.lang.String pageName)`	Returns the Class instance appropriate for a given component given a page name.
`PageClassLoaderContext`	`getRoot()`	Returns the root context.
`void`	`initialize(PageClassLoaderContext root, java.util.function.Function<java.lang.ClassLoader,PlasticProxyFactory> plasticProxyFactoryProvider)`	Initializes this service with the root context and a Plastic proxy factory provider.
`java.util.Set<java.lang.String>`	`invalidate(PageClassLoaderContext... contexts)`	Invalidates page classloader contexts and returns a set containing the names of all classes that should be invalidated.
`void`	`invalidateAndFireInvalidationEvents(PageClassLoaderContext... contexts)`	Invalidates page classloader contexts and invalidates the classes in the context as well.
`void`	`invalidateUnknownContext()`	Invalidates the "unknown" page classloader context context.
`boolean`	`isMerging()`	Returns whether contexts are being merged.
`void`	`preload()`	Preloads all data, first by collecting dependency data for all existing pages and the components, mixins and superclasses they use, then creating the page classloader contexts.
`void`	`preloadContexts()`	Preloads the page classloader contexts.

```
PageClassLoaderContext get(java.lang.String className)
```

    Parameters:
    
    className - the class fully qualified name. ClassLoader} and returns a new PlasticProxyFactory.
    
    Returns:
    
    the PageClassLoaderContext associated with that class.
  - invalidate
```
java.util.Set<java.lang.String> invalidate(PageClassLoaderContext... contexts)
```
    Invalidates page classloader contexts and returns a set containing the names of all classes that should be invalidated.
  - invalidateAndFireInvalidationEvents
```
void invalidateAndFireInvalidationEvents(PageClassLoaderContext... contexts)
```
    Invalidates page classloader contexts and invalidates the classes in the context as well.
  - getRoot
```
PageClassLoaderContext getRoot()
```
    Returns the root context.
  - clear
```
void clear()
```

```
boolean isMerging()
```
    Returns whether contexts are being merged.
  - clear
```
void clear(java.lang.String className)
```
    Removes one specific class from this manager, invalidating the context where it is.
  - initialize
```
void initialize(PageClassLoaderContext root,
                java.util.function.Function<java.lang.ClassLoader,PlasticProxyFactory> plasticProxyFactoryProvider)
```
    Initializes this service with the root context and a Plastic proxy factory provider. Method can only be called once. None of the parameters may be null.
  - getClassInstance
```
java.lang.Class<?> getClassInstance(java.lang.Class<?> clasz,
                                    java.lang.String pageName)
```
    Returns the Class instance appropriate for a given component given a page name.
    
    Parameters:
    
    clasz - the class instance.
    
    pageName - the page name.
    
    Returns:
    
    a Class instance.
  - invalidateUnknownContext
```
void invalidateUnknownContext()
```
    Invalidates the "unknown" page classloader context context.
  - preload
```
void preload()
```
    Preloads all data, first by collecting dependency data for all existing pages and the components, mixins and superclasses they use, then creating the page classloader contexts.
  - preloadContexts
```
void preloadContexts()
```
    Preloads the page classloader contexts.
