Examples with ConstantExpression org.apache.camel.model.language.ConstantExpression used on opensource projects

Example 1 with ConstantExpression

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

the class ProcessorDefinition method loop.

/**
     * <a href="http://camel.apache.org/loop.html">Loop EIP:</a>
     * Creates a loop allowing to process the a message a number of times and possibly process them
     * in a different way.
     *
     * @param count  the number of times
     * @return the builder
     */
public LoopDefinition loop(int count) {
    LoopDefinition loop = new LoopDefinition(new ConstantExpression(Integer.toString(count)));
    addOutput(loop);
    return loop;
}

Example 2 with ConstantExpression

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

the class ProcessorDefinition method pollEnrich.

/**
     * 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 resourceUri            URI 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.
     * @param aggregateOnException   whether to call {@link org.apache.camel.processor.aggregate.AggregationStrategy#aggregate(org.apache.camel.Exchange, org.apache.camel.Exchange)} if
     *                               an exception was thrown.
     * @return the builder
     * @see org.apache.camel.processor.PollEnricher
