The TinyBuilder class is responsible for taking a stream of SAX events and constructing
a Document tree, using the "TinyTree" implementation.
attribute
public void attribute(int nameCode,
int typeCode,
CharSequence value,
int locationId,
int properties)
throws XPathException
Notify an attribute. Attributes are notified after the startElement event, and before any
children. Namespaces and attributes may be intermingled.
- attribute in interface Receiver
nameCode
- The name of the attribute, as held in the name pooltypeCode
- The type of the attribute, as held in the name pool. The additional bit
NodeInfo.IS_DTD_TYPE may be set to indicate a DTD-derived type.value
- the string value of the attributelocationId
- an integer which can be interpreted using a LocationProvider
to return
information such as line number and system ID. If no location information is available,
the value zero is supplied.properties
- Bit significant value. The following bits are defined:
characters
public void characters(CharSequence chars,
int locationId,
int properties)
throws XPathException
Callback interface for SAX: not for application use
- characters in interface Receiver
comment
public void comment(CharSequence chars,
int locationId,
int properties)
throws XPathException
Callback interface for SAX: not for application use
- comment in interface Receiver
getLastCompletedElement
public NodeInfo getLastCompletedElement()
Get the last completed element node. This is used during checking of schema assertions,
which happens while the tree is still under construction. This method is called immediately after
a call on endElement(), and it returns the element that has just ended.
- the last completed element node, that is, the element whose endElement event is the most recent
endElement event to be reported
getSizeParameters
public int[] getSizeParameters()
Get the size parameters for the tree
- an array of four integers giving the actual number of non-attribute nodes, the actual
number of attributes, the actual number of namespace declarations, and the actual total length of
character data
getTree
public TinyTree getTree()
Get the tree being built by this builder
namespace
public void namespace(int namespaceCode,
int properties)
throws XPathException
Notify a namespace. Namespaces are notified after the startElement event, and before
any children for the element. The namespaces that are reported are only required
to include those that are different from the parent element. The events represent namespace
declarations and undeclarations rather than in-scope namespace nodes: an undeclaration is represented
by a namespace code of zero. If the sequence of namespace events contains two
A namespace must not conflict with any namespaces already used for element or attribute names.
- namespace in interface Receiver
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.properties
- The most important property is REJECT_DUPLICATES. If this property is set, the
namespace declaration will be rejected if it conflicts with a previous declaration of the same
prefix. If the property is not set, the namespace declaration will be ignored if it conflicts
with a previous declaration. This reflects the fact that when copying a tree, namespaces for child
elements are emitted before the namespaces of their parent element. Unfortunately this conflicts
with the XSLT rule for complex content construction, where the recovery action in the event of
conflicts is to take the namespace that comes last. XSLT therefore doesn't recover from this error:
it sets the REJECT_DUPLICATES flag, and this is treated as a hard error.
processingInstruction
public void processingInstruction(String piname,
CharSequence remainder,
int locationId,
int properties)
throws XPathException
Callback interface for SAX: not for application use
- processingInstruction in interface Receiver
setSizeParameters
public void setSizeParameters(int[] params)
Set the size parameters for the tree
params
- an array of four integers giving the expected number of non-attribute nodes, the expected
number of attributes, the expected number of namespace declarations, and the expected total length of
character data
setUnparsedEntity
public void setUnparsedEntity(String name,
String uri,
String publicId)
Set an unparsed entity in the document
- setUnparsedEntity in interface Receiver
startContent
public void startContent()
Notify the start of the content, that is, the completion of all attributes and namespaces.
Note that the initial receiver of output from XSLT instructions will not receive this event,
it has to detect it itself. Note that this event is reported for every element even if it has
no attributes, no namespaces, and no content.
- startContent in interface Receiver
startElement
public void startElement(int nameCode,
int typeCode,
int locationId,
int properties)
throws XPathException
Notify the start tag of an element
- startElement in interface Receiver
