Examples with ELContext jakarta.el.ELContext used on opensource projects

Example 16 with ELContext

use of jakarta.el.ELContext in project tomcat by apache.

the class TestValueExpressionImpl method testBug49345.

@Test
public void testBug49345() {
    ExpressionFactory factory = ExpressionFactory.newInstance();
    ELContext context = new ELContextImpl(factory);
    TesterBeanA beanA = new TesterBeanA();
    TesterBeanB beanB = new TesterBeanB();
    beanB.setName("Tomcat");
    beanA.setBean(beanB);
    ValueExpression var = factory.createValueExpression(beanA, TesterBeanA.class);
    context.getVariableMapper().setVariable("beanA", var);
    ValueExpression ve = factory.createValueExpression(context, "${beanA.bean.name}", String.class);
    // First check the basics work
    String result = (String) ve.getValue(context);
    Assert.assertEquals("Tomcat", result);
    // Now check the value reference
    ValueReference vr = ve.getValueReference(context);
    Assert.assertNotNull(vr);
    Assert.assertEquals(beanB, vr.getBase());
    Assert.assertEquals("name", vr.getProperty());
}

Example 17 with ELContext

use of jakarta.el.ELContext in project tomcat by apache.

the class TestScopedAttributeELResolverPerformance method testGetValuePerformance.

     * With the caching of NotFound responses this test takes ~20ms. Without the
     * caching it takes ~6s.
     */
@Test

        resolver.getValue(context, null, "unknown");
    }
}

Example 18 with ELContext
