Constructor Detail

JSPWikiMarkupParser

public JSPWikiMarkupParser(Context context,
                           java.io.Reader in)

Creates a markup parser.

Parameters:

context - The WikiContext which controls the parsing

in - Where the data is read from.

Method Detail

callMutatorChain

protected java.lang.String callMutatorChain(java.util.Collection<StringTransmutator> list,
                                            java.lang.String text)

Calls a transmutator chain.

Parameters:

list - Chain to call

text - Text that should be passed to the mutate() method of each of the mutators in the chain.

Returns:

The result of the mutation.

makeHeadingAnchor

protected java.lang.String makeHeadingAnchor(java.lang.String baseName,
                                             java.lang.String title,
                                             Heading hd)

Modifies the "hd" parameter to contain proper values. Because an "id" tag may only contain [a-zA-Z0-9:_-], we'll replace the % after url encoding with '_'.

Counts also duplicate headings (= headings with similar name), and attaches a counter.

makeHeading

public org.jdom2.Element makeHeading(int level,
                                     java.lang.String title,
                                     Heading hd)

Returns XHTML for the heading.

Parameters:

level - The level of the heading. @see Heading

title - the title for the heading

hd - a List to which heading should be added

Returns:

An Element containing the heading

parseToken

protected int parseToken(int ch)
                  throws java.io.IOException

Return CHARACTER, if you think this was a plain character; ELEMENT, if you think this was a wiki markup element, and IGNORE, if you think we should ignore this altogether.

To add your own MarkupParser, you can override this method, but it is recommended that you call super.parseToken() as well to gain advantage of JSPWiki's own markup. You can call it at the start of your own parseToken() or end - it does not matter.

Parameters:

ch - The character under investigation

Returns:

ELEMENT, CHARACTER or IGNORE.

Throws:

java.io.IOException - If parsing fails.

parse

public WikiDocument parse()
                   throws java.io.IOException

Parses the entire document from the Reader given in the constructor or set by MarkupParser.setInputReader(Reader).

Specified by:

parse in class MarkupParser

Returns:

A WikiDocument, ready to be passed to the renderer.

Throws:

java.io.IOException - If parsing cannot be accomplished.
