public class TypeCheckingFilter extends ProxyReceiver
Note that the TypeCheckingFilter cannot currently check document node tests of the form document-node(element(X,Y)), so it is not invoked in such cases. This isn't a big problem, because most instructions that return document nodes materialize them anyway.
Method Summary | |
---|---|
void | append(Item item, int locationId, int copyNamespaces)
Output an item (atomic value or node) to the sequence |
void | attribute(int nameCode, int typeCode, CharSequence value, int locationId, int properties)
Notify an attribute. |
void | characters(CharSequence chars, int locationId, int properties)
Character data |
void | close()
End of event stream |
void | comment(CharSequence chars, int locationId, int properties)
Output a comment |
void | endDocument()
Notify the end of a document node |
void | endElement()
End of element |
void | namespace(int namespaceCode, int properties)
Notify a namespace. |
void | processingInstruction(String target, CharSequence data, int locationId, int properties)
Processing Instruction |
void | setRequiredType(ItemType type, int cardinality, RoleLocator role, SourceLocator locator) |
void | startDocument(int properties)
Start of a document node. |
void | startElement(int nameCode, int 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 |
Parameters: nameCode The name of the attribute, as held in the name pool typeCode The type of the attribute, as held in the name pool properties Bit significant value. The following bits are defined:
Throws: IllegalStateException: attempt to output an attribute when there is no open element start tag
Parameters: namespaceCode an integer: the top half is a prefix code, the bottom half a URI code. These may be translated into an actual prefix and URI using the name pool. A prefix code of zero represents the empty prefix (that is, the default namespace). A URI code of zero represents a URI of "", that is, a namespace undeclaration.
Throws: IllegalStateException: attempt to output a namespace when there is no open element start tag
Parameters: nameCode integer code identifying the name of the element within the name pool. typeCode integer code identifying the element's type within the name pool. properties properties of the element node
Returns: true if the Receiver makes any use of this information. If false, the caller may supply untyped nodes instead of supplying the type annotation
