Class CachingProcessor<IN extends MessageProvider,OUT extends MessageProvider>

java.lang.Object

com.github.fge.jsonschema.core.processing.CachingProcessor<IN,OUT>

Type Parameters:

IN - input type for that processor

OUT - output type for that processor

All Implemented Interfaces:

Processor<IN,OUT>

public final class CachingProcessor<IN extends MessageProvider,OUT extends MessageProvider>
extends Object
implements Processor<IN,OUT>

A class caching the result of a Processor

You can use this over whichever processor of your choice. Internally, it uses a LoadingCache to store results.

You can optionally pass an Equivalence as an argument for cache keys. By default, Equivalences.equals() will be used.

Constructor Detail

CachingProcessor

public CachingProcessor(Processor<IN,OUT> processor)

Constructor

This is equivalent to calling CachingProcessor(Processor, Equivalence) with Equivalences.equals() as the second argument.

Parameters:

processor - the processor

CachingProcessor

public CachingProcessor(Processor<IN,OUT> processor,
                        Equivalence<IN> equivalence)

CachingProcessor

public CachingProcessor(Processor<IN,OUT> processor,
                        Equivalence<IN> equivalence,
                        int cacheSize)

Main constructor

Parameters:

processor - the processor

equivalence - an equivalence to use for cache keys

cacheSize - the size of the cache, zero disables it

Throws:

NullPointerException - processor or equivalence

Method Detail

process

public OUT process(ProcessingReport report,
                   IN input)
            throws ProcessingException

Description copied from interface: Processor

Specified by:

process in interface Processor<IN extends MessageProvider,OUT extends MessageProvider>

Parameters:

report - the report to use while processing

input - the input for this processor

Returns:

the output

Throws:
