public class FieldChecker
A FieldChecker is instantiated when a field in an identity constraint is matched; it receives notification of all events until the end of the element (or attribute) that matched the selector.

void |
characters(CharSequence chars,
int locationId,

Notify character data. |
void |
close()
The close() method is called immediately before the Watch is destroyed, that is, when the element whose declaration scopes the constraint implemented by this Watch goes out of scope. |
void |
endElement()
Notify the end of an element. |
void |
notifySelectedAttribute(FleetingNode attribute,
int locationId)
Notify an attribute that matches the selection. |
void |
setNamespaceResolver(NamespaceResolver resolver)
Set a NamespaceResolver for use by the FieldChecker |
void |
startElement(NodeName nameCode,
SchemaType typeCode,
int locationId,
int properties)
Notify the start of an element |
boolean |
usesTypeAnnotations()
Ask whether this Receiver (or the downstream pipeline) makes any use of the type annotations supplied on element and attribute events |
