                               Parser parser)

parse

@ParametersAreNonnullByDefault
Document parse(java.io.Reader input,
               java.lang.String baseUri,

newInstance

Create a new copy of this TreeBuilder

Returns:

copy, ready for a new parse

parseFragment

abstract java.util.List<Node> parseFragment(java.lang.String inputFragment,
                                            Element context,

protected void runParser()

process

protected abstract boolean process(Token token)

processStartTag

protected boolean processStartTag(java.lang.String name)

processStartTag

public boolean processStartTag(java.lang.String name,
                               Attributes attrs)

processEndTag

protected boolean processEndTag(java.lang.String name)

currentElement

protected Element currentElement()

Get the current element (last on the stack). If all items have been removed, returns the document instead (which might not actually be on the stack; use stack.size() == 0 to test if required.

Returns:

the last element on the stack, if any; or the root document

currentElementIs

protected boolean currentElementIs(java.lang.String normalName)

Checks if the Current Element's normal name equals the supplied name.

Parameters:

normalName - name to check

Returns:

true if there is a current element on the stack, and its name equals the supplied

error

protected void error(java.lang.String msg)

If the parser is tracking errors, add an error at the current position.

Parameters:

msg - error message

error

protected void error(java.lang.String msg,
                     java.lang.Object... args)

If the parser is tracking errors, add an error at the current position.

Parameters:

msg - error message template

args - template arguments

isContentForTagData

protected boolean isContentForTagData(java.lang.String normalName)

(An internal method, visible for Element. For HTML parse, signals that script and style text should be treated as Data Nodes).

tagFor

protected Tag tagFor(java.lang.String tagName,
                     ParseSettings settings)
