public abstract class ElementCreator extends ParentNodeConstructor
Modifier and Type | Field and Description |
---|---|
protected boolean |
inheritNamespaces
The inheritNamespaces flag indicates that the namespace nodes on the element created by this instruction
are to be inherited (copied) on the children of this element.
|
protected boolean |
validating
The validating flag is set if the type attribute is set or if validation is set to anything other than
preserve.

Modifier and Type | Method and Description |
---|---|
protected void |
checkContentForAttributes(StaticContext env)
Check statically whether the content of the element creates attributes or namespaces
after creating any child nodes
|
int |
computeSpecialProperties()
Get the static properties of this expression (other than its type).
|
Item |
evaluateItem(XPathContext context)
Evaluate the constructor, returning the constructed element node.
|
int[] |
getActiveNamespaces()
Callback to get a list of the intrinsic namespaces that need to be generated for the element.
|
int |
getImplementationMethod()
An implementation of Expression must provide at least one of the methods evaluateItem(), iterate(), or process().
|
ItemType |
getItemType(TypeHierarchy th)
Get the item type of the value returned by this instruction
|
abstract int |
getNameCode(XPathContext context) |
abstract java.lang.String |
getNewBaseURI(XPathContext context)
Get the base URI for the element being constructed
|
int |
getValidationMode()
Get the validation mode for the constructed element
|
boolean |
isInheritNamespaces()
Determine whether the inherit namespaces flag is set
|
boolean |
isValidating()
Determine whether this elementCreator performs validation
|
protected abstract void |
outputNamespaceNodes(XPathContext context,
Receiver receiver)
Callback to output namespace nodes for the new element.
|
TailCall |
processLeavingTail(XPathContext context)
Evaluate the instruction to produce a new element node.
|
void |
setValidationMode(int mode)
Set the validation mode for the new element
|
void |
suppressValidation(int validationMode)
Suppress validation on contained element constructors, on the grounds that the parent element
is already performing validation.
