public final class TinyElementImpl
A node in the XML parse tree representing an XML element.
This class is an implementation of NodeInfo. The object is a wrapper around one entry in the arrays maintained by the TinyTree. Note that the same node might be represented by different TinyElementImpl objects at different times.

For elements and attributes, this is the type annotation as defined in XDM. For document nodes, it should be one of XS_UNTYPED if the document has not been validated, or XS_ANY_TYPE if validation has taken place (that is, if any node in the document has an annotation other than Untyped or UntypedAtomic).

Types derived from a DTD are not reflected in the result of this method.

- where no typed value is available, for example in the case of

. However, this method is often more convenient and may be
more efficient, especially in the common case where the value is expected to be a singleton.

buffer
- If this is non-null, and the result array fits in this buffer, then the result
may overwrite the contents of this array, to avoid the cost of allocating a new array on the heap.
For a node other than an element, the method returns null.
public static NamespaceBinding[] getDeclaredNamespaces(TinyTree tree, int nodeNr, NamespaceBinding[] buffer)
tree
- The tree containing the given element nodenodeNr
- The node number of the given element node within the tinyTreebuffer
- If this is non-null, and the result array fits in this buffer, then the result
may overwrite the contents of this array, to avoid the cost of allocating a new array on the heap.
For a node other than an element, the method returns null.

copyOptions
- receiver
- the Receiver to which the node should be copied. It is the caller's
responsibility to ensure that this Receiver is open before the method is called
(or that it is self-opening), and that it is closed after use.locationId
- If non-zero, identifies the location of the instruction
that requested this copy. If zero, indicates that the location information

prefix
- the namespace prefix. May be the zero-length string, indicating
that there is no prefix. This indicates either the default namespace or the
null namespace, depending on the value of useDefault.useDefault
- true if the default namespace is to be used when the
prefix is "". If false, the method returns "" when the prefix is "".
