| AbstractItem | | abstract public class AbstractItem implements Item,Node,Serializable,Cloneable(Code) | | A semi-implemented item for leaf vertices.
A leaf item is a item without any children.
For cores having child cores, use Group.
Important methods that the deriving might want to override.
- Item.getName
- It must be overrided to provide a local name.
- Item.setName
- Overrid it if it allows to change the name.
Default: throws an exception.
- Item.getText
- Override it if it has a text representation.
Default: returns null.
- Item.setText
- Overrid it if it allows to change the text.
Default: throws an exception.
- Node.getNodeType
- It must be overrided to provide the type.
- Item.clone
- Override it if any other members to handle specially.
Note: by definition, we do deep clone only.
- Object.toString
- Override if you want a representation other than
XMLOutputter does.

|
| checkWritable | | final protected void checkWritable()(Code) | | Checks whether this item is writable (ie, isReady).
exception:
DOMException - with NO_MODIFICATION_ALLOWED_ERR if not writable |
| clearModified | | public void clearModified(boolean includingDescendant)(Code) | | |
| clone | | public Item clone(boolean preserveModified)(Code) | | |
| clone | | public Object clone()(Code) | | Clones this object (a deep cloning not including contents contained
in Textual nodes).
Note: after cloning, the read-only flag always becomes false,
and the parent becomes null (i.e., detached).

| setNodeValue | | public void setNodeValue(String nodeValue)(Code) | | |
| setReadonly | | public void setReadonly(boolean readonly)(Code) | | Sets the read-only flag of this item. It causes this item
and all its descendants read-only, see
AbstractItem.isReadonly .
Deriving class might restrict more conditions here.
