into
the current node. This method is called from the
cloneNode
method which is, in turn, called by the
cloneTree
method.
For any NodeComponent objects
contained by the object being duplicated, each NodeComponent
object's duplicateOnCloneTree
value is used to determine
whether the NodeComponent should be duplicated in the new node
or if just a reference to the current node should be placed in the
new node. This flag can be overridden by setting the
forceDuplicate
parameter in the cloneTree
method to true
.
originalNode
- the original node to duplicate.forceDuplicate
- when set to true
, causes the
duplicateOnCloneTree
flag to be ignored. When
false
, the value of each node's
duplicateOnCloneTree
variable determines whether
NodeComponent data is duplicated or copied.Node.cloneTree()
