$entry->add_link('something', 'has_part')->add_link('somethingelse', 'has_part');
.. etc
$writer->add_entry($entry);
$xmlstr = $writer->to_xml();

__construct(stdclass $user)   X-Ref

param: array $files array of stored_files to link

validate()   X-Ref

to_xml()   X-Ref
Return the entire feed as a string.
Then, it calls for validation

return: string feeds' content in xml

Class: portfolio_format_leap2a_entry  - X-Ref

This class represents a single leap2a entry.

__construct($id, $title, $type, $content=null)   X-Ref

http://wiki.cetis.ac.uk/2009-03/LEAP2A_types

param: string $title title of the entry. This is pure atom.
param: string $type the leap type of this entry.
param: mixed $content the content of the entry. string (xhtml/html/text)

At the moment this just makes sure required fields exist
but it could also check things against a list, for example


add_link($otherentry, $reltype, $displayorder=null)   X-Ref
Add a link from this entry to another one.
These will be collated at the end of the export (during to_xml)
and validated at that point. This function does no validation

param: portfolio_format_leap2a_entry|string $otherentry portfolio_format_leap2a_entry or its id
param: string $reltype (no leap2: ns required)

return: portfolio_format_leap2a_entry the current entry object. This is so that these calls can be chained
