Example 16 with ExpressionFactory

use of javax.el.ExpressionFactory in project tomcat70 by apache.

the class TestELParser method bug56185.

@Test
public void bug56185() {
    ExpressionFactory factory = ExpressionFactory.newInstance();
    ELContext context = new ELContextImpl();
    TesterBeanC beanC = new TesterBeanC();
    ValueExpression var = factory.createValueExpression(beanC, TesterBeanC.class);
    context.getVariableMapper().setVariable("myBean", var);
    ValueExpression ve = factory.createValueExpression(context, "${(myBean.int1 > 1 and myBean.myBool) or " + "((myBean.myBool or myBean.myBool1) and myBean.int1 > 1)}", Boolean.class);
    Assert.assertEquals(Boolean.FALSE, ve.getValue(context));
    beanC.setInt1(2);
    beanC.setMyBool1(true);
    Assert.assertEquals(Boolean.TRUE, ve.getValue(context));
}

Example 17 with ExpressionFactory

use of javax.el.ExpressionFactory in project tomcat70 by apache.

@Test
public void testJavaKeyWordIdentifier() {
    ExpressionFactory factory = ExpressionFactory.newInstance();
    ELContext context = new ELContextImpl();
    TesterBeanA beanA = new TesterBeanA();
    beanA.setInt("five");
    ValueExpression var = factory.createValueExpression(beanA, TesterBeanA.class);
    context.getVariableMapper().setVariable("this", var);
    // Should fail
    Exception e = null;
    try {
        factory.createValueExpression(context, "${this}", String.class);
    } catch (ELException ele) {

Example 18 with ExpressionFactory

use of javax.el.ExpressionFactory in project jersey by jersey.

the class LinkELContextTest method testEmbeddedExpression.

@Test
public void testEmbeddedExpression() {
    System.out.println("Embedded expression");
    ExpressionFactory factory = ExpressionFactory.newInstance();
    LinkELContext context = new LinkELContext(new EntityBean(), null);
    ValueExpression expr = factory.createValueExpression(context, "foo/${entity.id}/bar", String.class);
    Object value = expr.getValue(context);
    assertEquals("foo/" + ID + "/bar", value);
}

Example 19 with ExpressionFactory

use of javax.el.ExpressionFactory in project jersey by jersey.

@Test
public void testMultipleExpressions() {
    System.out.println("Multiple expressions");
    ExpressionFactory factory = ExpressionFactory.newInstance();
    LinkELContext context = new LinkELContext(new EntityBean(), null);
    ValueExpression expr = factory.createValueExpression(context, "foo/${entity.id}/bar/${entity.name}", String.class);
    Object value = expr.getValue(context);
    assertEquals("foo/" + ID + "/bar/" + NAME, value);
}

Example 20 with ExpressionFactory

use of javax.el.ExpressionFactory in project camel by apache.

the class JuelExpression method evaluate.

public <T> T evaluate(Exchange exchange, Class<T> tClass) {
    // Create (if needed) the ExpressionFactory first from the CamelContext using FactoryFinder
    ExpressionFactory factory = getExpressionFactory(exchange.getContext());
    ELContext context = populateContext(createContext(), exchange);
    ValueExpression valueExpression = factory.createValueExpression(context, expression, type);
    Object value = valueExpression.getValue(context);
    LOG.trace("Value returned {}", value);
    return exchange.getContext().getTypeConverter().convertTo(tClass, value);
}
