• 如果beanClassName与evaluated不同,则以evaluated为准。 • 否则,通过beanClassName获得它所对应的Class实例对象。 针对“步骤2”的mbdToUse.prepareMethodOverrides()方法是用于检查查找方法是否存在并确定其重载状态,其源码和注释如下所示: public void prepareMethodOverrides() throws BeanDefinitionValidationExceptio...
Since RS codes are a special class of nonbinary BCH codes, they can be decoded using the same decoding algorithm already explained in the previous section. To improve the burst error correction capability of RS codes, RS code can be combined with an inner binary block code in a concatenation...
