Class: content_writer  - X-Ref

An implementation of the content_writer for use in unit tests.

This implementation does not export any data but instead stores it in
structures within the instance which can be easily queried for use
during unit tests.

has_any_data($subcontext = [])   X-Ref
Whether any data has been exported at all within the current context.

param: array $subcontext The location within the current context that this data belongs -
return: bool

has_any_data_in_any_context()   X-Ref
Whether any data has been exported for any context.

return: bool

__construct(\core_privacy\local\request\writer $writer)   X-Ref
Constructor for the content writer.

Note: The writer_factory must be passed.
param: \core_privacy\local\request\writer          $writer    The writer factory.

set_context(\context $context)   X-Ref
Set the context for the current item being processed.

param: \context        $context    The context to use

get_current_context()   X-Ref
Return the current context.

return: \context

export_data(array $subcontext, \stdClass $data)   X-Ref
Export the supplied data within the current context, at the supplied subcontext.

param: array           $subcontext The location within the current context that this data belongs.
param: \stdClass       $data       The data to be exported

get_data(array $subcontext = [])   X-Ref
Get all data within the subcontext.

param: array           $subcontext The location within the current context that this data belongs.
return: array                       The metadata as a series of keys to value + descrition objects.

export_metadata(array $subcontext, string $key, $value, string $description)   X-Ref
Export metadata about the supplied subcontext.

Metadata consists of a key/value pair and a description of the value.

param: array           $subcontext The location within the current context that this data belongs.
param: string          $key        The metadata name.
param: string          $value      The metadata value.
param: string          $description    The description of the value.
return: $this

get_all_metadata(array $subcontext = [])   X-Ref
Get all metadata within the subcontext.

param: array           $subcontext The location within the current context that this data belongs.
return: array                       The metadata as a series of keys to value + descrition objects.

get_metadata(array $subcontext, $key, $valueonly = true)   X-Ref
Get the specified metadata within the subcontext.

param: array           $subcontext The location within the current context that this data belongs.
param: string          $key        The metadata to be fetched within the context + subcontext.
param: boolean         $valueonly  Whether to fetch only the value, rather than the value + description.
return: array                       The metadata as a series of keys to value + descrition objects.

export_related_data(array $subcontext, $name, $data)   X-Ref
Export a piece of related data.

param: array           $subcontext The location within the current context that this data belongs.
param: string          $name       The name of the file to be exported.
param: \stdClass       $data       The related data to export.

get_related_data(array $subcontext = [], $filename = null)   X-Ref
Get all data within the subcontext.

param: array           $subcontext The location within the current context that this data belongs.
param: string          $filename   The name of the intended filename.
return: array                       The metadata as a series of keys to value + descrition objects.

export_custom_file(array $subcontext, $filename, $filecontent)   X-Ref
Export a piece of data in a custom format.

param: array           $subcontext The location within the current context that this data belongs.
param: string          $filename   The name of the file to be exported.
param: string          $filecontent    The content to be exported.

get_custom_file(array $subcontext = [], $filename = null)   X-Ref
Get the specified custom file within the subcontext.

param: array           $subcontext The location within the current context that this data belongs.
param: string          $filename   The name of the file to be fetched within the context + subcontext.
return: string                      The content of the file.

rewrite_pluginfile_urls(array $subcontext, $component, $filearea, $itemid, $text)   X-Ref
Prepare a text area by processing pluginfile URLs within it.

Note that this method does not implement the pluginfile URL rewriting. Such a job tightly depends on how the
actual writer exports files so it can be reliably tested only in real writers such as
{@link core_privacy\local\request\moodle_content_writer}.

However we have to remove @@PLUGINFILE@@ since otherwise {@link format_text()} shows debugging messages

param: array           $subcontext The location within the current context that this data belongs.
param: string          $component  The name of the component that the files belong to.
param: string          $filearea   The filearea within that component.
param: string          $itemid     Which item those files belong to.
param: string          $text       The text to be processed
return: string                      The processed string

export_area_files(array $subcontext, $component, $filearea, $itemid)   X-Ref
Export all files within the specified component, filearea, itemid combination.

param: array           $subcontext The location within the current context that this data belongs.
param: string          $component  The name of the component that the files belong to.
param: string          $filearea   The filearea within that component.
param: string          $itemid     Which item those files belong to.

export_file(array $subcontext, \stored_file $file)   X-Ref
