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. |
boolean |
equals(java.lang.Object object)
|
java.lang.Object |
getBean()
Get the parent bean. |
java.lang.Object |
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. |
QName |
getName()
Returns the name of this node. |
abstract int |
getPropertyCount()
Count the number of properties represented. |
int |
getPropertyIndex()
Get the property index. |
abstract java.lang.String |
getPropertyName()
Get the property name. |
abstract java.lang.String[] |
getPropertyNames()
Get the names of the included properties. |
int |
hashCode()
|
boolean |
isActual()
An actual pointer points to an existing part of an object graph, even if it is null. |
protected abstract boolean |
isActualProperty()
Learn whether this pointer references an actual property. |
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 |
setPropertyIndex(int index)
Set the property index. |
abstract void |
setPropertyName(java.lang.String propertyName)
Set the property name. |
