public abstract class DefaultResourceHandler
extends ResourceHandlerWrapper

A default ResourceHandler implementation which hooks on all three createResource(String), createResource(String, String) and createResource(String, String, String) methods. Implementors should only need to override either getLibraryName() and createResourceFromLibrary(String, String), or decorateResource(Resource).

2.0

Constructor Details

DefaultResourceHandler

protected DefaultResourceHandler(ResourceHandler wrapped)

Creates a new instance of this default resource handler which wraps the given resource handler.

Parameters:

wrapped - The resource handler to be wrapped.

Method Details

createResource

public Resource createResource(String resourceName)

Delegate to decorateResource(Resource, String, String) with result of createResource(String) from the wrapped resource handler.

Implementors should not override this.

Overrides:

createResource in class ResourceHandlerWrapper

createResource

public Resource createResource(String resourceName,
 String libraryName)

If library name is not null and it equals getLibraryName(), then delegate to createResourceFromLibrary(String, String) with null as content type, else delegate to decorateResource(Resource, String, String) with result of createResource(String, String) from the wrapped resource handler.

Implementors should not override this.

Overrides:

createResource in class ResourceHandlerWrapper

createResource

public Resource createResource(String resourceName,
 String libraryName,
 String contentType)

If library name is not null and it equals getLibraryName(), then delegate to createResourceFromLibrary(String, String), else delegate to decorateResource(Resource, String, String) with result of createResource(String, String, String) from the wrapped resource handler.

Implementors should not override this.

Overrides:

createResource in class ResourceHandlerWrapper

getLibraryName

public String getLibraryName()

Returns the library name on which this resource handler implementation should listen. If a resource from specifically this library name is requested, then createResourceFromLibrary(String, String) will be called to create the resource, else decorateResource(Resource) will be called with result of the call from the wrapped resource handler.

The default implementation returns null.

Returns:

The library name on which this resource handler implementation should listen.

createResourceFromLibrary

public Resource createResourceFromLibrary(String resourceName,
 String contentType)

Returns the library-specific resource in case a resource from specifically the library name as identified by getLibraryName() is requested.

The default implementation returns null.

Parameters:

resourceName - The resource name.

contentType - The content type.

Returns:

The library-specific resource.

decorateResource

public Resource decorateResource(Resource resource,
 String resourceName,
 String libraryName)

Decorate the given resource. This will only be called if no library-specific resource has been requested.

The default implementation delegates to decorateResource(Resource).

Parameters:

resource - The resource to be decorated.

resourceName - The resource name.

libraryName - The library name.

Returns:

The decorated resource.

Since:

2.6

decorateResource

public Resource decorateResource(Resource resource)

Decorate the given resource. This will only be called if no library-specific resource has been requested.

The default implementation just returns the given resource unmodified.

Parameters:

resource - The resource to be decorated.

Returns:

The decorated resource.
