Examples with ValueReference javax.el.ValueReference used on opensource projects

Example 1 with ValueReference

use of javax.el.ValueReference in project tomcat by apache.

the class TestValueExpressionImpl method testGetValueReference.

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

Example 2 with ValueReference

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);
    assertEquals("Tomcat", result);
    // Now check the value reference
    ValueReference vr = ve.getValueReference(context);
    assertNotNull(vr);
    assertEquals(beanB, vr.getBase());
    assertEquals("name", vr.getProperty());
}

Example 3 with ValueReference

use of javax.el.ValueReference in project oxCore by GluuFederation.

the class ValueExpressionAnalyzer method getValueReference.

public ValueReference getValueReference(ELContext elContext) {
    InterceptingResolver resolver = new InterceptingResolver(elContext.getELResolver());
    try {
        expression.setValue(decorateELContext(elContext, resolver), null);
    } catch (ELException ele) {
        return null;
    }
    ValueReference reference = resolver.getValueReference();
    if (reference != null) {
        Object base = reference.getBase();
        if (base instanceof CompositeComponentExpressionHolder) {
            ValueExpression ve = ((CompositeComponentExpressionHolder) base).getExpression((String) reference.getProperty());
            if (ve != null) {
                this.expression = ve;
                reference = getValueReference(elContext);
            }
        }
    }
    return reference;
}

Example 4 with ValueReference

use of javax.el.ValueReference in project tomcat by apache.

the class TestValueExpressionImpl method testGetValueReferenceVariable.

@Test
public void testGetValueReferenceVariable() {
    ExpressionFactory factory = ExpressionFactory.newInstance();
    ELContext context = new ELContextImpl(factory);
    TesterBeanB beanB = new TesterBeanB();
    beanB.setName("Tomcat");
    ValueExpression var = factory.createValueExpression(beanB, TesterBeanB.class);
    context.getVariableMapper().setVariable("beanB", var);
    ValueExpression var2 = factory.createValueExpression(context, "${beanB.name}", String.class);
    context.getVariableMapper().setVariable("foo", var2);
    ValueExpression ve = factory.createValueExpression(context, "${foo}", ValueExpression.class);
    // Now check the value reference
    ValueReference vr = ve.getValueReference(context);
    assertNotNull(vr);
    assertEquals(beanB, vr.getBase());
    assertEquals("name", vr.getProperty());
}
