Constructor Summary | |
NullPropertyPointer(NodePointer parent)
|
Method Summary | |
java.lang.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,
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. |
java.lang.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. |
java.lang.Object |
getNodeValue()
Returns the object the pointer points to; does not convert it to a "canonical" type. |
int |
getPropertyCount()
|
java.lang.String |
getPropertyName()
|
java.lang.String[] |
getPropertyNames()
|
NodePointer |
getValuePointer()
Returns a NodePointer that can be used to access the currently selected property value. |
boolean |
isActual()
An actual pointer points to an existing part of an object graph, even if it is null. |
protected boolean |
isActualProperty()
|
boolean |
isCollection()
Returns true if the value of the pointer is an array or
a Collection. |
boolean |
isNode()
If false, this node is axiliary and can only be used as an intermediate in the chain of pointers. |
void |
setDynamic(boolean flag)
|
void |
setPropertyIndex(int index)
|
void |
setPropertyName(java.lang.String propertyName)
|
void |
setValue(java.lang.Object value)
Converts the value to the required type and changes the corresponding object to that value. |
