Examples with ValueBuilder org.apache.camel.builder.ValueBuilder used on opensource projects

Example 1 with ValueBuilder

use of org.apache.camel.builder.ValueBuilder in project camel by apache.

the class JpaRouteTest method testRouteJpa.

@Test
public void testRouteJpa() throws Exception {
    // should auto setup transaction manager and entity factory
    JpaComponent jpa = context.getComponent("jpa", JpaComponent.class);
    assertNotNull("Should have been auto assigned", jpa.getEntityManagerFactory());
    assertNotNull("Should have been auto assigned", jpa.getTransactionManager());
    MockEndpoint mock = getMockEndpoint("mock:result");
    mock.expectedMessageCount(1);
    ValueBuilder header = mock.message(0).header(JpaConstants.ENTITYMANAGER);
    header.isNotNull();
    header.isInstanceOf(EntityManager.class);
    template.sendBody("direct:start", new SendEmail("someone@somewhere.org"));
    assertMockEndpointsSatisfied();
    assertEntityInDB(1);
}

Example 2 with ValueBuilder

use of org.apache.camel.builder.ValueBuilder in project camel by apache.

the class BinaryExpression method createInExpression.

private Expression createInExpression(final Expression leftExp, final Expression rightExp) {
    return new Expression() {

        @Override
        public <T> T evaluate(Exchange exchange, Class<T> type) {
            // okay the in operator is a bit more complex as we need to build a list of values
            // from the right hand side expression.
            // each element on the right hand side must be separated by comma (default for create iterator)
            Iterator<Object> it = ObjectHelper.createIterator(rightExp.evaluate(exchange, Object.class));
            List<Object> values = new ArrayList<Object>();
            while (it.hasNext()) {
                values.add(it.next());
            }
            // then reuse value builder to create the in predicate with the list of values
            ValueBuilder vb = new ValueBuilder(leftExp);
            Predicate predicate = vb.in(values.toArray());
            if (operator == BinaryOperatorType.NOT_IN) {
                predicate = PredicateBuilder.not(predicate);
            }
            boolean answer = predicate.matches(exchange);
