Method Detail

parse

public Page parse(char[] buffer)
           throws java.io.IOException

Deprecated.

Description copied from interface: PageParser

Parse the given buffer into a Page object.

Specified by:

parse in interface PageParser

Parameters:

buffer - The buffer for the page.

Returns:

The parsed page

Throws:

java.io.IOException - if an error occurs

parse

public Page parse(SitemeshBuffer buffer)
           throws java.io.IOException

Deprecated.

Description copied from interface: PageParser

Parse the given buffer into a page object. DefaultSitemeshBuffer is the appropriate implementation of this interface to pass in.

Specified by:

parse in interface PageParser

Parameters:

buffer - The buffer for the page.

Returns:

The parsed page

Throws:

java.io.IOException - if an error occurs

writeTag

private static void writeTag(int state,
                             int laststate,
                             boolean hide,
                             CharArray _head,
                             CharArray _buffer,
                             CharArray _body)

Deprecated.

shouldWriteToHead

private static boolean shouldWriteToHead(int state,
                                         int laststate)

Deprecated.

parseTag

private FastPageParser.Tag parseTag(FastPageParser.Tag tag,
                                    CharArray buf)

Deprecated.

Populates a FastPageParser.Tag object using data from the supplied CharArray. The supplied tag parameter is reset and reused - this avoids excess object creation which hwlps performance.

Returns:

the same tag instance that was passed in, except it will be populated with a new name value (and the corresponding nameEndIdx value). However if the tag contained nathing but whitespace, this method will return null.

parseProperties

private static FastPageParser.Tag parseProperties(FastPageParser.Tag tag,
                                                  CharArray buffer)

Deprecated.

This is called when we need to extract the properties for the tag from the tag's HTML. We only call this when necessary since it has quite a lot of overhead.

Parameters:

tag - the tag that is currently being processed. This should be the tag that was returned as a result of a call to parseTag(FastPageParser.Tag, CharArray) (ie, it has the name and nameEndIdx fields set correctly for the tag in question. The properties field can be in an undefined state - it will get replaced regardless).

buffer - a CharArray containing the entire tag that is being parsed.

Returns:

the same tag instance that was passed in, only it will now be populated with any properties that were specified in the tag's HTML.
