setNodeFactory
public void setNodeFactory(NodeFactory factory)
Set the Node Factory to use. If none is specified, the Builder uses its own.

startElement
public void startElement(int nameCode, int typeCode, int locationId, int properties) throws XPathException
Notify the start of an element- 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. The value -1 indicates the default type, xdt:untyped.locationId
- an integer which can be interpreted using aLocationProvider
to return information such as line number and system ID. If no location information is available, the value zero is supplied.properties
- bit-significant properties of the element node. If there are no revelant properties, zero is supplied.- Throws:
XPathException
-
namespace
public void namespace(int namespaceCode, int properties)
Description copied from interface:Receiver
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.- 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.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.

attribute
public void attribute(int nameCode, int typeCode, java.lang.CharSequence value, int locationId, int properties) throws XPathException
Description copied from interface:Receiver
Notify an attribute. Attributes are notified after the startElement event, and before any children. Namespaces and attributes may be intermingled.- Parameters:
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.locationId
- an integer which can be interpreted using aLocationProvider
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:- DISABLE_ESCAPING
- Disable escaping for this attribute
- NO_SPECIAL_CHARACTERS
- Attribute value contains no special characters
- Throws:
XPathException
-
startContent
public void startContent() throws XPathException
Description copied from interface:Receiver
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.- Throws:
XPathException
-
endElement
public void endElement() throws XPathException
Notify the end of an element- Throws:
XPathException
-
characters
public void characters(java.lang.CharSequence chars, int locationId, int properties) throws XPathException
Notify a text node. Adjacent text nodes must have already been merged- Parameters:
chars
- The characterslocationId
- an integer which can be interpreted using aLocationProvider
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:- DISABLE_ESCAPING
- Disable escaping for this text node
- USE_CDATA
- Output as a CDATA section
- NO_SPECIAL_CHARACTERS
- Value contains no special characters
- WHITESPACE
- Text is all whitespace
- Throws:
XPathException
-
processingInstruction
public void processingInstruction(java.lang.String name, java.lang.CharSequence remainder, int locationId, int properties)
Notify a processing instruction- Parameters:
name
- The PI name. This must be a legal name (it will not be checked).remainder
- The data portion of the processing instructionlocationId
- an integer which can be interpreted using aLocationProvider
to return information such as line number and system ID. If no location information is available, the value zero is supplied.properties
- Additional information about the PI. The following bits are defined:- CHECKED
- Data is known to be legal (e.g. doesn't contain "?>")
-
comment
public void comment(java.lang.CharSequence chars, int locationId, int properties) throws XPathException
Notify a comment- Parameters:
chars
- The content of the commentlocationId
- an integer which can be interpreted using aLocationProvider
to return information such as line number and system ID. If no location information is available, the value zero is supplied.properties
- Additional information about the comment. The following bits are defined:- CHECKED
- Comment is known to be legal (e.g. doesn't contain "--")
- Throws:
XPathException
-
graftElement
public void graftElement(ElementImpl element) throws XPathException
graftElement() allows an element node to be transferred from one tree to another. This is a dangerous internal interface which is used only to contruct a stylesheet tree from a stylesheet using the "literal result element as stylesheet" syntax. The supplied element is grafted onto the current element as its only child.- Throws:
XPathException
-
setUnparsedEntity
public void setUnparsedEntity(java.lang.String name, java.lang.String uri, java.lang.String publicId)
Set an unparsed entity URI for the document- Parameters:
name
- The name of the unparsed entityuri
- The system identifier of the unparsed entitypublicId
- The public identifier of the unparsed entity
