org.apache.camel.support.AsyncProcessorSupport

org.apache.camel.processor.Enricher

All Implemented Interfaces:

org.apache.camel.AsyncProcessor, org.apache.camel.CamelContextAware, org.apache.camel.Processor, org.apache.camel.Service, org.apache.camel.ShutdownableService, org.apache.camel.spi.HasId, org.apache.camel.spi.IdAware, org.apache.camel.StatefulService, org.apache.camel.SuspendableService

public class Enricher
extends org.apache.camel.support.AsyncProcessorSupport
implements org.apache.camel.spi.IdAware, org.apache.camel.CamelContextAware

A content enricher that enriches input data by first obtaining additional data from a resource represented by an endpoint producer and second by aggregating input data and additional data. Aggregation of input data and additional data is delegated to an AggregationStrategy object.

Uses a Producer to obtain the additional data as opposed to PollEnricher that uses a PollingConsumer.

process

public boolean process(org.apache.camel.Exchange exchange,
                       org.apache.camel.AsyncCallback callback)

Enriches the input data (exchange) by first obtaining additional data from an endpoint represented by an endpoint producer and second by aggregating input data and additional data. Aggregation of input data and additional data is delegated to an AggregationStrategy object set at construction time. If the message exchange with the resource endpoint fails then no aggregation will be done and the failed exchange content is copied over to the original message exchange.

Specified by:

process in interface org.apache.camel.AsyncProcessor

Parameters:

exchange - input data.

resolveEndpoint

protected org.apache.camel.Endpoint resolveEndpoint(org.apache.camel.Exchange exchange,
                                                    Object recipient)

createResourceExchange

protected org.apache.camel.Exchange createResourceExchange(org.apache.camel.Exchange source,
                                                           org.apache.camel.ExchangePattern pattern)

Creates a new DefaultExchange instance from the given exchange. The resulting exchange's pattern is defined by pattern.

Parameters:

source - exchange to copy from.

pattern - exchange pattern to set.

Returns:

created exchange.
