  +--jp.ne.dti.lares.foozy.pagemixer.parser.LoosePageState

All Implemented Interfaces:

PageState

public class LoosePageState

extends java.lang.Object

implements PageState

Page parser simple implementation.

This implementation only focuses on markup language syntax.

Validity of (1)tag names and (2)data structure are ignored, so this focuses on parsing as many markup language sources as possible, in other words.

This can parse tokens shown below. Some of them are for parsing XHTML, XML, BML and so on.

• text
• comment(<!-- -->)
• start tag(<name>) with attributes
• end tag(</name>)
• empty tag(<name/>) with attributes
• DOCTYPE(<!DOCTYPE ... >) with internal subset
• CDATA(<![CDATA[ ... ]]>)
• embedded script(<% ... %gt;) like JSP/ASP and so on
• Processing Instruction(<?name ... ?>)

Constructor Detail

LoosePageState

public LoosePageState()

Constructor.

This is equivalent to LoosePageState(HTMLSymbolSet.SET, true).

LoosePageState

public LoosePageState(SymbolSet symbolSet)

Constructor.

This is equivalent to LoosePageState(symbolSet, true).

LoosePageState

public LoosePageState(SymbolSet symbolSet,
                      boolean ignoreCase)

Constructor.

Name of start/ end tag tokens and attributes are lower-cased to unify as symbol, if you specify true as 'ignoreCase'. If so, you can use both upper-case and lower-case for same names in same page.

ATTENTION: "DOCTYPE" for DocTypeToken and "CDATA" for CDATAToken are upper-cased, and name of processing instructions are parsed case sensitively always.

Parameters:

symbolSet - to resolve name of tokens and attributes

ignoreCase - whether name of tokens are case insensitive or not

push

protected void push(char c)

Push character to queue.

Parameters:

c - character to push

input

public Token input(char c)
            throws PageParseException

Description copied from interface: PageState

Parse next character.

Input next character in character sequence of page to parse, and return Token, if it recognizes.

Almost all Token, derived class in fact, consists of so many characters, so this method returns null frequently.

Specified by:

input in interface PageState

Following copied from interface: jp.ne.dti.lares.foozy.pagemixer.parser.PageState

Parameters:

c - next character in page to parse

Returns:

token if recognizes. otherwise null.

flush

public Token flush()
            throws PageParseException

Description copied from interface: PageState

Indicate no more character to parse.

Indicate there is no more character in character sequence of page to parse, and return Token, if it recognizes.

This method works like "input(EOF)".

Specified by:

flush in interface PageState

Following copied from interface: jp.ne.dti.lares.foozy.pagemixer.parser.PageState

Returns:

token if recognizes. otherwise null.

reset

public void reset()

Description copied from interface: PageState

Reset current status.

Reset current status of page state to re-use it.

This must not cause PageParseException though PageState.flush() may cause.

Specified by:

reset in interface PageState
