Examples with FeatureDescriptor java.beans.FeatureDescriptor used on opensource projects

Example 1 with FeatureDescriptor

use of java.beans.FeatureDescriptor in project tomcat by apache.

@Override
public Iterator<FeatureDescriptor> getFeatureDescriptors(ELContext context, Object base) {
    List<FeatureDescriptor> feats = new ArrayList<>(SCOPE_NAMES.length);
    FeatureDescriptor feat;
    for (int i = 0; i < SCOPE_NAMES.length; i++) {
        feat = new FeatureDescriptor();
        feat.setDisplayName(SCOPE_NAMES[i]);
        feat.setExpert(false);
        feat.setHidden(false);
        feat.setName(SCOPE_NAMES[i]);
        feat.setPreferred(true);
        feat.setValue(RESOLVABLE_AT_DESIGN_TIME, Boolean.TRUE);
        feat.setValue(TYPE, String.class);

        Object key;
        FeatureDescriptor desc;
        while (itr.hasNext()) {

            desc.setHidden(false);
            desc.setName(key.toString());
            desc.setPreferred(true);
            desc.setValue(RESOLVABLE_AT_DESIGN_TIME, Boolean.TRUE);
            desc.setValue(TYPE, key.getClass());
            feats.add(desc);
        }
        return feats.iterator();
    }
    return null;
}

Example 3 with FeatureDescriptor

use of java.beans.FeatureDescriptor in project tomcat by apache.

the class TestBeanELResolver method testGetFeatureDescriptors02.

/**
     * Tests that a valid FeatureDescriptors are returned.
     */
@Test
public void testGetFeatureDescriptors02() {
    BeanELResolver resolver = new BeanELResolver();
    ELContext context = new StandardELContext(ELManager.getExpressionFactory());
    Iterator<FeatureDescriptor> result = resolver.getFeatureDescriptors(context, new Bean());
    while (result.hasNext()) {
        PropertyDescriptor featureDescriptor = (PropertyDescriptor) result.next();
        Assert.assertEquals(featureDescriptor.getPropertyType(), featureDescriptor.getValue(ELResolver.TYPE));
        Assert.assertEquals(Boolean.TRUE, featureDescriptor.getValue(ELResolver.RESOLVABLE_AT_DESIGN_TIME));
    }
}

Example 4 with FeatureDescriptor

use of java.beans.FeatureDescriptor in project j2objc by google.

the class FeatureDescriptorTest method setUp.

@Override
protected void setUp() throws Exception {
    super.setUp();
    fd = new FeatureDescriptor();
}

Example 5 with FeatureDescriptor

use of java.beans.FeatureDescriptor in project Activiti by Activiti.

the class JsonNodeELResolver method getFeatureDescriptors.

/**
	 * If the base object is not null, returns an Iterator containing the set of JavaBeans
	 * properties available on the given object. Otherwise, returns null. The Iterator returned must
	 * contain zero or more instances of java.beans.FeatureDescriptor. Each info object contains
	 * information about a property in the bean, as obtained by calling the
	 * BeanInfo.getPropertyDescriptors method. The FeatureDescriptor is initialized using the same
	 * fields as are present in the PropertyDescriptor, with the additional required named
	 * attributes "type" and "resolvableAtDesignTime" set as follows:
	 * <ul>
	 * <li>{@link ELResolver#TYPE} - The runtime type of the property, from
	 * PropertyDescriptor.getPropertyType().</li>
	 * <li>{@link ELResolver#RESOLVABLE_AT_DESIGN_TIME} - true.</li>
	 * </ul>
	 * 
	 * @param context
	 *            The context of this evaluation.
	 * @param base
	 *            The bean to analyze.
	 * @return An Iterator containing zero or more FeatureDescriptor objects, each representing a
	 *         property on this bean, or null if the base object is null.
