org.apache.commons.jxpath.ri.model.dom.DOMAttributePointer
public class DOMAttributePointer
A Pointer that points to a DOM node. Because the underlying DOM Attr is not Serializable, neither is this pointer class truly so.

| Constructor Summary | |
|---|---|
DOMAttributePointer(NodePointer parent,
org.w3c.dom.Attr attr)
Create a new DOMAttributePointer. |
|
| Method Summary | |
|---|---|
String |
asPath()
Returns an XPath that maps to this Pointer. |
int |
compareChildNodePointers(NodePointer pointer1,
NodePointer pointer2)
Compares two child NodePointers and returns a positive number, zero or a positive number according to the order of the pointers. |
boolean |
equals(Object object)
|
Object |
getBaseValue()
Returns the value represented by the pointer before indexing. |
Object |
getImmediateNode()
Returns the object the pointer points to; does not convert it to a "canonical" type. |
int |
getLength()
If the pointer represents a collection (or collection element), returns the length of the collection. |
QName |
getName()
Returns the name of this node. |
String |
getNamespaceURI()
Returns the namespace URI associated with this Pointer. |
Object |
getValue()
By default, returns getNode(), can be overridden to
return a "canonical" value, like for instance a DOM element should
return its string value. |
int |
hashCode()
|
boolean |
isActual()
An actual pointer points to an existing part of an object graph, even if it is null. |
boolean |
isCollection()
Returns true if the value of the pointer is an array or
a Collection. |
boolean |
isLeaf()
If true, this node does not have children |
void |
remove()
Remove the node of the object graph this pointer points to. |
void |
setValue(Object value)
Sets the value of this attribute. |
boolean |
testNode(NodeTest nodeTest)
Checks if this Pointer matches the supplied NodeTest. |
