Constructor Detail

TinyBuilder

public TinyBuilder()

Create a TinyTree builder

Method Detail

attribute

public void attribute(int nameCode, int typeCode, CharSequence value, int locationId, int properties)

characters

public void characters(CharSequence chars, int locationId, int properties)

Callback interface for SAX: not for application use

comment

public void comment(CharSequence chars, int locationId, int properties)

Callback interface for SAX: not for application use

endDocument

public void endDocument()

Callback interface for SAX: not for application use

endElement

public void endElement()

Callback interface for SAX: not for application use

getCurrentDepth

public int getCurrentDepth()

Get the current depth in the tree

Returns: the current depth

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.

Returns: 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

Returns: 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

Returns: the TinyTree

makeTextNode

protected int makeTextNode(CharSequence chars, int len)

Create a text node. Separate method so it can be overridden

Parameters: chars the contents of the text node len the length of the text node

namespace

public void namespace(int namespaceCode, int properties)

open

public void open()

Open the event stream

processingInstruction

public void processingInstruction(String piname, CharSequence remainder, int locationId, int properties)

Callback interface for SAX: not for application use

reset

public void reset()

setSizeParameters

public void setSizeParameters(int[] params)

Set the size parameters for the tree

Parameters: 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
