public abstract class ElementCreator extends ParentNodeConstructor
Modifier and Type | Field and Description |
---|---|
protected boolean |
inheritNamespacesFromParent
The inheritNamespacesFromParent flag indicates that this element should inherit the namespaces of its
parent element in the result tree.
|
protected boolean |
inheritNamespacesToChildren
The inheritNamespacesToChildren flag indicates that the namespace nodes on the element created by this instruction
are to be inherited (copied) on the children of this element.

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
|
int |
computeSpecialProperties()
Get the static properties of this expression (other than its type).

NamespaceBinding[] |
getActiveNamespaces()
Callback to get a list of the intrinsic namespaces that need to be generated for the element.
|
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

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 |
isInheritNamespacesFromParent()
Ask whether this element inherits namespaces from its parent.
|
boolean |
isInheritNamespacesToChildren()
Ask whether the inherit namespaces flag is set
|
abstract void |
outputNamespaceNodes(XPathContext context,
Receiver receiver,
NodeName nameCode,
NodeInfo copiedNode)
Callback to output namespace nodes for the new element.
|
TailCall |
processLeavingTail(XPathContext context)
Evaluate the instruction to produce a new element node.
|
TailCall |
processLeavingTail(XPathContext context,
NodeInfo copiedNode)
Evaluate the instruction to produce a new element node.
|
void |
setInheritanceFlags(java.lang.String flags) |
void |
setInheritNamespacesFromParent(boolean inherit)
Say whether this element causes inherits namespaces from its parent.
|
void |
setInheritNamespacesToChildren(boolean inherit)
Say whether this element causes its children to inherit namespaces
|
void |
suppressValidation(int parentValidationMode)
Suppress validation on contained element constructors, on the grounds that the parent element
is already performing validation.
