Method Detail

getMinimizeFreeProcessors

public static <T> Collection<T> getMinimizeFreeProcessors(Collection<T> processors)

Returns a collection free of minimize aware processors (annotated with @Minimize).

Type Parameters:

T - type of processor

Parameters:

processors - a collection of processors.

isMinimizeAwareProcessor

public static <T> boolean isMinimizeAwareProcessor(T processor)

getSupportedResourceType

public static <T> SupportedResourceType getSupportedResourceType(T processor)

getProcessorsByType

public static <T> Collection<T> getProcessorsByType(ResourceType type,
                                                    Collection<T> availableProcessors)

Type Parameters:

T - processor type. Can be ResourcePreProcessor, ResourcePostProcessor or null (any).

Parameters:

type - ResourceType to apply for searching on available processors.

availableProcessors - a list where to perform the search.

Returns:

a list of found processors which satisfy the search criteria. There are 3 possibilities:

• If you search by null (any) type - you'll get only processors which can be applied on any resource (not any particular type)
• If you search by JS type - you'll get processors which can be applied on JS resources & any (null) resources
• If you search by CSS type - you'll get processors which can be applied on CSS resources & any (null) resources

toPostProcessor

public static ResourcePostProcessor toPostProcessor(ResourcePreProcessor preProcessor)

Transforms a preProcessor into a postProcessor.

Parameters:

preProcessor - ResourcePreProcessor to transform.

toPreProcessor

public static ResourcePreProcessor toPreProcessor(ResourcePostProcessor postProcessor)

Transforms a postProcessor into a preProcessor.

Parameters:

postProcessor - ResourcePostProcessor to transform.

findPreProcessorByClass

public static final <T extends ResourcePreProcessor> T findPreProcessorByClass(Class<T> processorClass,
                                                                               Collection<ResourcePreProcessor> preProcessors)

Returns:

preProcessor of type processorClass if any found or null otherwise.

createPreProcessorsMap

public static Map<String,ResourcePreProcessor> createPreProcessorsMap()

createPostProcessorsMap

public static Map<String,ResourcePostProcessor> createPostProcessorsMap()
