| Method Summary | |
|---|---|
String |
asPath()
Returns an XPath that maps to this Pointer. |
NodePointer |
createChild(JXPathContext context,
QName name,
int index)
Called by a child pointer when it needs to create a parent object for a non-existent collection element. |
NodePointer |
createChild(JXPathContext context,
QName name,
int index,
Object value)
Called by a child pointer if that child needs to assign the value supplied in the createPath(context, value) call to a non-existent node. |
NodePointer |
createPath(JXPathContext context)
Called by a child pointer when it needs to create a parent object. |
NodePointer |
createPath(JXPathContext context,
Object value)
Called directly by JXPathContext. |
boolean |
equals(Object object)
|
Object |
getBaseValue()
Returns the value represented by the pointer before indexing. |
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. |
PropertyPointer |
getPropertyPointer()
Get a PropertyPointer for this PropertyOwnerPointer. |
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 |
