|
void |
addAttributes(Map<String,Object> attributes)
Add or replace each attribute found in attributes.
|
void |
changeAttribute(String attribute,
Object... values)
Like
Element.addAttribute(String, Object...) but for consistency. |

An iterable view on the set of attribute keys usable within a for-each
loop.
|
<T> T |
getFirstAttributeOf(Class<T> clazz,
String... keys)
Like
Element.getAttribute(String, Class) , but returns the first existing
attribute in a list of keys, instead of only one key. |

CompoundAttribute
interface are considered like hashes since they
can be transformed to a hash. If an attribute with the same name exists
but is not a hash, null is returned. We cannot enforce the type of the
key. It is considered a string and you should use "Object.toString()" to
get it.public String getId()
