ElementCreator()
Construct an ElementCreator.
|
Modifier and Type | Method and Description |
---|---|
protected void |
checkContentSequence(StaticContext env)
Check statically whether the content of the element creates attributes or namespaces
after creating any child nodes
|
protected int |
computeSpecialProperties()
Get the static properties of this expression (other than its type).
|
int |
getCardinality()
Determine the static cardinality of the expression.
|
abstract NodeName |
getElementName(XPathContext context,
NodeInfo copiedNode)
Determine (at run-time) the name code of the element being constructed
|
int |
getImplementationMethod()
An implementation of Expression must provide at least one of the methods evaluateItem(), iterate(), or process().
|
ItemType |
getItemType()
Get the item type of the value returned by this instruction
|
abstract java.lang.String |
getNewBaseURI(XPathContext context,
NodeInfo copiedNode)
Get the base URI for the element being constructed
|
java.lang.String |
getStreamerName()
Get the (partial) name of a class that supports streaming of this kind of expression
|
boolean |
isBequeathNamespacesToChildren()
Ask whether the inherit namespaces flag is set
|
boolean |
isInheritNamespacesFromParent()
Ask whether this element inherits namespaces from its parent.
|
abstract void |
outputNamespaceNodes(Outputter receiver,
NodeName nodeName,
NodeInfo copiedNode)
Callback to output namespace bindings for the new element.
|
TailCall |
processLeavingTail(Outputter output,
XPathContext context)
Evaluate the instruction to produce a new element node.
|
TailCall |
processLeavingTail(Outputter out,
XPathContext context,
NodeInfo copiedNode)
Evaluate the instruction to produce a new element node.
|
void |
setBequeathNamespacesToChildren(boolean inherit)
Say whether this element causes its children to inherit namespaces
|
void |
setInheritanceFlags(java.lang.String flags) |
void |
setInheritNamespacesFromParent(boolean inherit)
Say whether this element causes inherits namespaces from its parent.
|
void |
suppressValidation(int parentValidationMode)
Suppress validation on contained element constructors, on the grounds that the parent element
is already performing validation.
