Overrides:

copyStringValue in class AbstractNode

Throws:

javax.xml.transform.TransformerException

setSystemId

public void setSystemId(java.lang.String uri)

This method is present to ensure that the class implements the javax.xml.transform.Source interface, so a node can be used as the source of a transformation.

setParentNode

protected void setParentNode(TinyNodeImpl parent)

Set the parent of this node. Providing this information is useful, if it is known, because otherwise getParent() has to search backwards through the document.

isSameNode

compareOrder in class AbstractNode

Parameters:

other - The other node, whose position is to be compared with this node

Returns:

-1 if this node precedes the other node, +1 if it follows the other node, or 0 if they are the same node. (In this case, isSameNode() will always return true, and the two nodes will produce the same result for generateId())
