Examples of java.beans.IndexedPropertyDescriptor

java.beans.IndexedPropertyDescriptor
An IndexedPropertyDescriptor describes a property that acts like an array and has an indexed read and/or indexed write method to access specific elements of the array.
An indexed property may also provide simple non-indexed read and write methods. If these are present, they read and write arrays of the type returned by the indexed read method.

        for (PropertyDescriptor element : propertyDesc) {
            if (element.getName().equals("class")) {
                assertNull(element.getWriteMethod());
                assertNotNull(element.getReadMethod());
            } else {
                IndexedPropertyDescriptor indexedDesc = (IndexedPropertyDescriptor) element;
                assertEquals("fox501", element.getName());
                assertNull(element.getPropertyType());
                assertNull(element.getWriteMethod());
                assertNull(element.getReadMethod());
                assertNull(indexedDesc.getIndexedReadMethod());
                assertNotNull(indexedDesc.getIndexedWriteMethod());
                assertEquals(Integer.class.getName(), indexedDesc
                        .getIndexedPropertyType().getName());
            }
        }
