Example 8 with SimpleExpression

use of org.apache.camel.model.language.SimpleExpression in project camel by apache.

the class ProcessorDefinition method pollEnrichRef.

/**
     * The <a href="http://camel.apache.org/content-enricher.html">Content Enricher EIP</a>
     * enriches an exchange with additional data obtained from a <code>resourceUri</code>
     * using a {@link org.apache.camel.PollingConsumer} to poll the endpoint.
     * <p/>
     * The difference between this and {@link #enrich(String)} is that this uses a consumer
     * to obtain the additional data, where as enrich uses a producer.
     * <p/>
     * The timeout controls which operation to use on {@link org.apache.camel.PollingConsumer}.
     * If timeout is negative, we use <tt>receive</tt>. If timeout is 0 then we use <tt>receiveNoWait</tt>
     * otherwise we use <tt>receive(timeout)</tt>.
     *
     * @param resourceRef            Reference of resource endpoint for obtaining additional data.
     * @param timeout                timeout in millis to wait at most for data to be available.
     * @param aggregationStrategyRef Reference of aggregation strategy to aggregate input data and additional data.
     * @return the builder
     * @see org.apache.camel.processor.PollEnricher
     * @deprecated use pollEnrich with a <tt>ref:id</tt> as the resourceUri parameter.
