Member Function Documentation

add_stored_file()

core_search\document::add_stored_file ( $file )

inherited

Add a stored file to the document.

Parameters

stored_file | int

$file

The file to add, or file id.

Return values

void

apply_defaults()

search_solr\document::apply_defaults ( )

protected

Apply any defaults to unset fields before export.

Called after document building, but before export.

Sub-classes of this should make sure to call parent\apply_defaults().

Reimplemented from core_search\document.

export_doc()

core_search\document::export_doc ( \renderer_base $output )

inherited

Returns the current docuement information.

Adding more info than the required one as themers and ws clients might be interested in showing more stuff.

Although content is a required field when setting up the document, it accepts '' (empty) values as they may be the result of striping out HTML.

SECURITY NOTE: It is the responsibility of the document to properly escape any text to be displayed. The renderer will output the content without any further cleaning.

Parameters

renderer_base

$output

The renderer.

Return values

array

export_file_for_engine()

search_solr\document::export_file_for_engine

(

$file

)

Export the data for the given file in relation to this document.

Parameters

stored_file

$file

The stored file we are talking about.

Return values

array

export_for_engine()

core_search\document::export_for_engine ( )

inherited

Returns the document ready to submit to the search engine.

Exceptions

coding_exception

Return values

array

export_for_template() [1/2]

core_search\document::export_for_template ( \renderer_base $output )

inherited

Export the document data to be used as a template context.

Just delegates all the processing to export_doc_info, also used by external functions. Adding more info than the required one as people might be interested in extending the template.

Parameters

renderer_base

$output

The renderer.

Return values

array

export_for_template() [2/2]

templatable::export_for_template ( renderer_base $output )

inherited

Function to export the renderer data in a format that is suitable for a mustache template.

This means:

1. No complex types - only stdClass, array, int, string, float, bool
2. Any additional info that is required for the template is pre-calculated (e.g. capability checks).

Parameters

renderer_base

$output

Used to do a final render of any components that need to be rendered for export.

Return values

stdClass|array

format_string_for_engine()

static search_solr\document::format_string_for_engine ( $string )

static

Formats the timestamp according to the search engine needs.

Parameters

int

$timestamp

Return values

string

Reimplemented from core_search\document.

format_text()

search_solr\document::format_text ( $text )

protected

Formats a text string coming from the search engine.

Even if this is called through an external function it is fine to return HTML as HTML is considered solr's search engine text format. An external function can ask for raw text, but this just means that it will not pass through format_text, no that we can not add HTML.

Parameters

string

$text

Text to format

string

HTML text to be renderer

format_text_for_engine()

$requiredfields

All required fields any doc should contain.

We have to choose a format to specify field types, using solr format as we have to choose one and solr is the default search engine.

Search engine plugins are responsible of setting their appropriate field types and map these naming to whatever format they need.
