net.sf.saxon.tree.linked.DocumentImpl
public final class DocumentImpl
A node in the XML parse tree representing the Document itself (or equivalently, the root node of the Document).
A DocumentImpl object may either represent a real document node, or it may represent an imaginary container for a parentless element.

node - the node to be added as a child of this node. This must be an instance of
NodeImpl. It will be modified as a result of this call (by setting its
parent property and sibling position)index - the position where the child is to be added
public void insertChildren(NodeInfo[] source,
boolean atStart,
boolean inherit)
This method takes no action unless the target node is a document node or element node. It also takes no action in respect of any supplied nodes that are not elements, text nodes, comments, or processing instructions.
The supplied nodes will form the new children. Adjacent text nodes will be merged, and zero-length text nodes removed. The supplied nodes may be modified in situ, for example to change their parent property and to add namespace bindings, or they may be copied, at the discretion of the implementation.
insertChildren in interface MutableNodeInfoinsertChildren in class NodeImplsource - the nodes to be inserted. The implementation determines what implementation classes
of node it will accept; this implementation will accept text, comment, and processing instruction
nodes belonging to any implementation, but elements must be instances of ElementImpl.
The supplied nodes will be modified in situ, for example
to change their parent property and to add namespace bindings, if they are instances of
ElementImpl; otherwise they will be copied. If the nodes are copied, then on return
the supplied source array will contain the copy rather than the original.atStart - true if the new nodes are to be inserted before existing children; false if they are
to be inserted after existing childreninherit - true if the inserted nodes are to inherit the namespaces of their new parent; false
if such namespaces are to be undeclared
IllegalArgumentException - if the supplied nodes use a node implementation that this
implementation does not accept.
protected void insertChildrenAt(NodeInfo[] source,
int index,
boolean inherit)
source - the children to be inserted. We allow any kind of text, comment, or processing instruction
node, but element nodes must be instances of this NodeInfo implementation.index - the position before which they are to be inserted: 0 indicates insertion before the
first child, 1 insertion before the second child, and so on.inherit - true if the inserted nodes are to inherit the namespaces that are in-scope for their
new parent; false if such namespaces should be undeclared on the children
protected void replaceChildrenAt(NodeInfo[] source,
int index,
boolean inherit)
source - the children to be insertedindex - the position at which they are to be inserted: 0 indicates replacement of the
first child, replacement of the second child, and so on. The effect is undefined if index
is out of rangeinherit - set to true if the new child elements are to inherit the in-scope namespaces
of their new parent
IllegalArgumentException - if any of the replacement nodes is not an element, text,
comment, or processing instruction nodepublic void compact(int size)
size - the number of actual children
