All Implemented Interfaces:

ImportAware, MinimizeAware, ResourcePostProcessor, ResourcePreProcessor, SupportAware, SupportedResourceTypeAware, ObjectDecorator<ResourcePreProcessor>

public final class PathPatternProcessorDecorator
extends ProcessorDecorator

A ProcessorDecorator with Ant path style support. This processor requires AntPathMatcher provided by spring framework.

The implementation is inspired from mwa project created by Edgar Espina.

Since:

1.5.0

Method Detail

include

public static PathPatternProcessorDecorator include(Object processor,
                                                    String... patterns)

Decorates a processor which will be applied on provided patterns.

Parameters:

processor - The processor to decorate.

patterns - an array of patterns on which the processor will be applied.

Returns:

decorated processor.

exclude

public static PathPatternProcessorDecorator exclude(Object processor,
                                                    String... patterns)

Decorates a processor which will not be applied on provided patterns.

Parameters:

processor - The processor to decorate.

patterns - an array of patterns on which the processor will not be applied.

Returns:

decorated processor.

process

public void process(Resource resource,
                    Reader reader,
                    Writer writer)
             throws IOException

Process a content supplied by a reader and perform some sort of processing. It is important to know that you should use reader for processing instead of trying to access the resource original content using Resource, because this way you can ignore the other preProcessors from the chain.
It is not require to explicitly handle exception. When the processing fails, the following can happen:

• the exception is wrapped in RuntimeException and the processing chain is interrupted (by default)
• content remains unchanged (if WroConfiguration.isIgnoreFailingProcessor() is true)

It is not required to close the reader and writers, because these will be closed for you.

Specified by:

process in interface ResourcePreProcessor

Overrides:

process in class ProcessorDecorator

Parameters:

resource - the original resource as it found in the model.

reader - Reader used to read processed resource content.

writer - Writer where used to write processed results.

Throws:

IOException - when an exception occurs. The future version will change the exception type to Exception, because any exception may occur during processing. The processing failure will be handled based on value of WroConfiguration.isIgnoreFailingProcessor() configuration flag.

toString

public String toString()

Overrides:

toString in class ProcessorDecorator
