Interface MergedResourcePicker2

public interface MergedResourcePicker2

Service interface which can be implemented to define an algorithm used to pick resources to be merged. For each picker service, a separate ResourceProviderFactory will be exposed at the MERGE_ROOT of the picker.

Since:

1.2

Method Detail

pickResources

java.util.List<Resource> pickResources(ResourceResolver resolver,
                                       java.lang.String relativePath,
                                       Resource relatedResource)

Method invoked by the MergingResourceProvider to identify the resources to be merged for a given relative path. The resources returned may be either resources returned from the ResourceResolver directory or an instance of NonExistingResource. Returning an empty list will cause the resource to not exist for consumers (resolver.getResource(path) will return null).

Parameters:

resolver - the ResourceResolver

relativePath - the path relative to the merge root

relatedResource - an optional resource which is related to the given path (always the parent resource or null)

Returns:

a List of Resource objects
