public class ElemTemplateElement
extends UnImplNode
implements PrefixResolver, Serializable, ExpressionNode, WhitespaceStrippingElementMatcher, XSLTVisitable

An instance of this class represents an element inside an xsl:template class. It has a single "execute" method which is expected to perform the given action on the result tree. This class acts like a Element node, and implements the Element interface, but is not a full implementation of that interface... it only implements enough for basic traversal of the tree.

Method Details

appendChild

public Node appendChild(Node newChild)
            throws DOMException
Add a child to the child list. NOTE: This presumes the child did not previously have a parent. Making that assumption makes this a less expensive operation -- but requires that if you *do* want to reparent a node, you use removeChild() first to remove it from its previous context. Failing to do so will damage the tree.
Overrides:
appendChild in interface UnImplNode
Parameters:
newChild - Child to be added to child list
Returns:
Child just added to the child list

appendChild

public ElemTemplateElement appendChild(ElemTemplateElement elem)
Add a child to the child list. NOTE: This presumes the child did not previously have a parent. Making that assumption makes this a less expensive operation -- but requires that if you *do* want to reparent a node, you use removeChild() first to remove it from its previous context. Failing to do so will damage the tree.
Parameters:
Returns:
Child just added to the child list

compareTo

public int compareTo(Object o)
            throws ClassCastException
Compares this object with the specified object for precedence order. The order is determined by the getImportCountComposed() of the containing composed stylesheet and the getUid() of this element. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.
Parameters:
