Methods

Modifier and Type	Method and Description
void	characters(char[] ch, int start, int length) Callback interface for SAX: not for application use
void	comment(char[] ch, int start, int length) Callback interface for SAX (part of LexicalHandler interface): not for application use
void	endDocument() Callback interface for SAX: not for application use
void	endElement(int nameCode) Callback interface for SAX: not for application use
void	graftElement(ElementImpl element) graftElement() allows an element node to be transferred from one tree to another.
void	processingInstruction(String name, String remainder) Callback interface for SAX: not for application use Note: because SAX1 does not deliver comment nodes, we get these in the form of a processing instruction with a null name.
void	setDocumentLocator(Locator locator) Callback interface for SAX: not for application use
void	setNodeFactory(NodeFactory factory) Set the Node Factory to use.
void	setUnparsedEntity(String name, String uri) Set an unparsed entity URI for the document

TreeBuilder

public TreeBuilder()

create a Builder and initialise variables

Method Detail

setNodeFactory

public void setNodeFactory(NodeFactory factory)

Set the Node Factory to use. If none is specified, the Builder uses its own.

startDocument

public void startDocument()
                   throws TransformerException

Callback interface for SAX: not for application use

Specified by:

startDocument in class Emitter

Throws:

TransformerException

endDocument

public void endDocument()
                 throws TransformerException

Callback interface for SAX: not for application use

Specified by:

endDocument in class Emitter

Throws:

TransformerException

setDocumentLocator

public void setDocumentLocator(Locator locator)

Callback interface for SAX: not for application use

Overrides:

setDocumentLocator in class Emitter

startElement

public void startElement(int nameCode,
                Attributes attributes,
                int[] namespaces,
                int namespacesUsed)
                  throws TransformerException

Callback interface for SAX: not for application use

Specified by:

startElement in class Emitter

namespaces - Array of namespace codes identifying the namespace prefix/uri pairs associated with this element

namespacesUsed - Number of significant entries within namespaces array

Throws:

TransformerException

endElement

public void endElement(int nameCode)
                throws TransformerException

Callback interface for SAX: not for application use

Specified by:

endElement in class Emitter

Throws:

TransformerException

characters

public void characters(char[] ch,
              int start,
              int length)
                throws TransformerException

Callback interface for SAX: not for application use

Specified by:

characters in class Emitter

Throws:

TransformerException

processingInstruction

public void processingInstruction(String name,
                         String remainder)

Callback interface for SAX: not for application use
Note: because SAX1 does not deliver comment nodes, we get these in the form of a processing instruction with a null name. This requires a specially-adapted SAX driver.

Specified by:

processingInstruction in class Emitter

comment

public void comment(char[] ch,
           int start,
           int length)
             throws TransformerException

Callback interface for SAX (part of LexicalHandler interface): not for application use

Specified by:

comment in class Emitter

Throws:

TransformerException

graftElement

public void graftElement(ElementImpl element)
                  throws TransformerException

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:

TransformerException

setUnparsedEntity

public void setUnparsedEntity(String name,
                     String uri)

Set an unparsed entity URI for the document

Specified by:

setUnparsedEntity in class Builder
