Class: repository_type  - X-Ref

This class is used to manage repository plugins

A repository_type is a repository plug-in. It can be Box.net, Flick-r, ...
A repository type can be edited, sorted and hidden. It is mandatory for an
administrator to create a repository type in order to be able to create
some instances of this type.
Coding note:
- a repository_type object is mapped to the "repository" database table
- "typename" attibut maps the "type" database field. It is unique.
- general "options" for a repository type are saved in the config_plugin table
- when you delete a repository, all instances are deleted, and general
options are also deleted from database
- When you create a type for a plugin that can't have multiple instances, a
instance is automatically created.

This function is used to copy a moodle file to draft area.

It DOES NOT check if the user is allowed to access this file because the actual file
can be located in the area where user does not have access to but there is an alias
to this file in the area where user CAN access it.

param: string $reference this reference is generated by
param: stored_file $storedfile created file reference

reference_file_selected($reference, $context, $component, $filearea, $itemid)   X-Ref
reference_file_selected

This function is called when a controlled link file is selected in a file picker and the form is
saved. The expected behaviour for repositories supporting controlled links is to
- copy the file to the moodle system account
- put it in a folder that reflects the context it is being used
- make sure the sharing permissions are correct (read-only with the link)
- return a new reference string pointing to the newly copied file.

param: string $reference this reference is generated by

The result of the function is stored in files.source field. It may be analysed
when the source file is lost or repository may use it to display human-readable
location of reference original.

This method is called when file is picked for the first time only. When file
(either copy or a reference) is already in moodle and it is being picked
again to another file area (also as a copy or as a reference), the value of
files.source is copied.

Prepare file reference information

param: string $source source of the file, returned by repository as 'source' and received back from user (not cleaned)
return: string file reference, ready to be stored

prepare_file($filename)   X-Ref
Get a unique file path in which to save the file.

The filename returned will be removed at the end of the request and
should not be relied upon to exist in subsequent requests.

param: string $filename file name
return: file path

has_moodle_files()   X-Ref
Does this repository used to browse moodle files?

return: bool

get_link($url)   X-Ref
Return file URL, for most plugins, the parameter is the original
url, but some plugins use a file id, so we need this function to
convert file id to original url.

param: string $url the url of file
return: string

get_file($url, $filename = '')   X-Ref
Downloads a file from external repository and saves it in temp dir

Function get_file() must be implemented by repositories that support returntypes
FILE_INTERNAL or FILE_REFERENCE. It is invoked to pick up the file and copy it
to moodle. This function is not called for moodle repositories, the function
{@link repository::copy_to_area()} is used instead.

This function can be overridden by subclass if the files.reference field contains
not just URL or if request should be done differently.

param: string $url the content of files.reference field, in this implementaion
param: string $filename filename (without path) to save the downloaded file in the
return: array with elements:

import_external_file_contents(stored_file $file, $maxbytes = 0)   X-Ref
Downloads the file from external repository and saves it in moodle filepool.
This function is different from {@link repository::sync_reference()} because it has
bigger request timeout and always downloads the content.

This function is invoked when we try to unlink the file from the source and convert
a reference into a true copy.

param: stored_file $file
param: int $maxbytes throw an exception if file size is bigger than $maxbytes (0 means no limit)

get_file_size($source)   X-Ref
Return size of a file in bytes.

param: string $source encoded and serialized data of file
return: int file size in bytes

is_visible()   X-Ref
Return is the instance is visible
(is the type visible ? is the context enable ?)

return: bool

can_be_edited_by_user()   X-Ref
Can the instance be edited by the current user?

The property $readonly must not be used within this method because
it only controls if the options from self::get_instance_option_names()
can be edited.

return: bool true if the user can edit the instance.

get_name()   X-Ref
Return the name of this instance, can be overridden.

return: string

contains_private_data()   X-Ref
Is this repository accessing private data?

This function should return true for the repositories which access external private
data from a user. This is the case for repositories such as Dropbox, Google Docs or Box.net
which authenticate the user and then store the auth token.

Of course, many repositories store 'private data', but we only want to set
contains_private_data() to repositories which are external to Moodle and shouldn't be accessed
to by the users having the capability to 'login as' someone else. For instance, the repository
'Private files' is not considered as private because it's part of Moodle.

You should not set contains_private_data() to true on repositories which allow different types
of instances as the levels other than 'user' are, by definition, not private. Also
the user instances will be protected when they need to.

return: boolean True when the repository accesses private external data.

supported_filetypes()   X-Ref
What kind of files will be in this repository?

return: array return '*' means this repository support any files, otherwise

supported_returntypes()   X-Ref
Tells how the file can be picked from this repository

Maximum value is FILE_INTERNAL | FILE_EXTERNAL | FILE_REFERENCE

return: int

default_returntype()   X-Ref
Tells how the file can be picked from this repository

Maximum value is FILE_INTERNAL | FILE_EXTERNAL | FILE_REFERENCE

This method is intended to be a callback when deleting
a course or a user to delete all the instances associated
to their context. The usual way to delete a single instance
is to use {@link self::delete()}.

This function can only update fields filepath, filename, author, license.
If anything (except filepath) is updated, timemodified is set to current time.
If filename or filepath is updated the file unconnects from it's origin

Function repository::reset_caches() is deprecated, cache is handled by MUC now.


sync_external_file($file, $resetsynchistory = false)   X-Ref
Function repository::sync_external_file() is deprecated. Use repository::sync_reference instead


sync_reference(stored_file $file)   X-Ref
Performs synchronisation of an external file if the previous one has expired.

This function must be implemented for external repositories supporting
FILE_REFERENCE, it is called for existing aliases when their filesize,
contenthash or timemodified are requested. It is not called for internal
repositories (see {@link repository::has_moodle_files()}), references to
internal files are updated immediately when source is modified.

Referenced files may optionally keep their content in Moodle filepool (for
thumbnail generation or to be able to serve cached copy). In this
case both contenthash and filesize need to be synchronized. Otherwise repositories
should use contenthash of empty file and correct filesize in bytes.

Note that this function may be run for EACH file that needs to be synchronised at the
moment. If anything is being downloaded or requested from external sources there
should be a small timeout. The synchronisation is performed to update the size of
the file and/or to update image and re-generated image preview. There is nothing
fatal if syncronisation fails but it is fatal if syncronisation takes too long
and hangs the script generating a page.

Note: If you wish to call $file->get_filesize(), $file->get_contenthash() or
$file->get_timemodified() make sure that recursion does not happen.

Called from {@link stored_file::sync_external_file()}

param: stored_file $file
return: bool false when file does not need synchronisation, true if it was synchronised

build_source_field($source)   X-Ref
Build draft file's source field

{@link file_restore_source_field_from_draft_file()}
XXX: This is a hack for file manager (MDL-28666)
For newly created  draft files we have to construct
source filed in php serialized data format.
File manager needs to know the original file information before copying
to draft area, so we append these information in mdl_files.source field

param: string $source
return: string serialised source field

prepare_to_cache()   X-Ref
Prepares the repository to be cached. Implements method from cacheable_object interface.

return: array

wake_from_cache($data)   X-Ref
