Constructor Summary | |
PropertyPointer(NodePointer parent)
Takes a javabean, a descriptor of a property of that object and an offset within that property (starting with 0). |
Method Summary | |
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. |
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,
java.lang.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,
java.lang.Object value)
Called directly by JXPathContext. |

getImmediateNode()
Returns the object the pointer points to; does not convert it to a "canonical" type. |
NodePointer |
getImmediateValuePointer()
Returns a NodePointer that can be used to access the currently selected property value. |
int |
getLength()
If the property contains a collection, then the length of that collection, otherwise - 1. |

isActualProperty()
|
boolean |
isCollection()
Returns true if the value of the pointer is an array or
a Collection. |
