Java5关于方法泛型的一个用法

	protected<T> void setCurrentAttribute(List<T> entities, String name) {
		for (T entity : entities) {
			ExtAttrVo[] attributes = ((BaseExtAttrObject)entity).getExtAttrList();
			for (ExtAttrVo attr : attributes) {
				if (name.equals(attr.getExtAttrName())) {
					((BaseExtAttrObject)entity).getCurrentAttribute(attr.getExtAttrName());
					break;
				}
			}
		}
	}

protected<T> void setCurrentAttribute(List<T extends  BaseExtAttrObject> entities, String name) {
for (T entity : entities) {
ExtAttrVo[] attributes = ((BaseExtAttrObject)entity).getExtAttrList();
for (ExtAttrVo attr : attributes) {
if (name.equals(attr.getExtAttrName())) {
((BaseExtAttrObject)entity).getCurrentAttribute(attr.getExtAttrName());
break;
}
}
}
}

这样严谨些
