Returns a duplicate of the node, i.e. serves as a generic
copy constructor for nodes.
- The duplicate node has no parent, i.e. A::Node.parentNode
is DOM::null. SRC::DOM1, DOM2, DOM3
- The duplicate node has no user data, i.e. user data
associated to the node is not carried over. However,
if any IF::UserDataHandlers has been specified along with
the associated data, those handlers will be called with
the appropriate parameters before the method returns. SRC::DOM3
- If the node is an IF::Element, all attributes and their values,
including those representing defaulted attributes (i.e.
attributes whose A::Attr.specified are DOM::false),
but the method does not copy any children it contains
unless it is a deep clone (i.e. P::deep is DOM::true).
SRC::DOM1, DOM2, DOM3
- Cloning an IF::Attr directly, as oppsed to be cloned
as part of an IF::Element cloning operation, returns
a specified attribute (i.e. its A::Attr.specified is
set to DOM::true). SRC::DOM1, DOM2, DOM3
- Cloning an IF::Attr always clones its children, since
they represent its value, no matter whether this is a
deep clone or not. SRC::DOM3
- Cloning an IF::tx|EntityReference automatically constructs
its subtree if a corresponding IF::tx|Entity is available,
no matter whether this is a deep clone or not. SRC::DOM3
- Cloning an IF::Attr always clones its children, since
they represent its value, no matter whether this is a
deep clone or not. SRC::DOM3
- Cloning an IF::tx|EntityReference automatically constructs
its subtree if a corresponding IF::tx|Entity is available,
no matter whether this is a deep clone or not. SRC::DOM3
- Cloning any other type of node simply returns a copy of the node.
SRC::DOM1, DOM2, DOM3
- Cloning an immutable subtree results in a mutable copy, but
the children of an IF::tx|EntityReference clone are
read-only. SRC::DOM2, DOM3
- Cloning IF::Document, IF::tx|DocumentType, IF::tx|Entity,
IF::tx|Notation nodes is implementation dependent.
SRC::DOM1SE, DOM2, DOM3
- Cloning an immutable subtree results in a mutable copy, but
the children of an IF::tx|EntityReference clone are
read-only. SRC::DOM2, DOM3
- Cloning a node does not copy the event listeners attached to it.
SRC::DOM2 Events, DOM3 Events
{NOTE:: IF::UserDataHandlers are prohibitted to throw exceptions;
if a IF::UserDataHandler that is registered to the node
being cloned throws an exception, then the result of
the method is undefined.
NOT_SUPPORTED_ERR:
The node is of type IF::Document, IF::tx|DocumentType,
IF::tx|Entity, or IF::tx|Notation and the implementation
does not support cloning that type of node. SRC::DOM1SE
Only in DOM1SE; they are implementation dependent
in DOM1SE, DOM2, and DOM3.
