Constructor & Destructor Documentation

ApiQueryImageInfo::__construct	(	$	mainModule,
		$	moduleName,
		$	modulePrefix = `'ii'`
	)

Constructor.

Parameters:

	$mainModule	ApiMain object

Member Function Documentation

ApiQueryImageInfo::execute ( )

Evaluates the parameters, performs the requested query, and sets up the result.

Concrete implementations of ApiBase must override this method to provide whatever functionality their module offers. Implementations must not produce any output on their own and are not expected to handle any errors.

The execute() method will be invoked directly by ApiMain immediately before the result of the module is output. Aside from the constructor, implementations should assume that no other methods will be called externally on the module before the result is processed.

The result data should be stored in the ApiResult object available through getResult().

Reimplemented from ApiBase.

ApiQueryImageInfo::getAllowedParams ( )

Returns an array of allowed parameters (parameter name) => (default value) or (parameter name) => (array with PARAM_* constants as keys) Don't call this function directly: use getFinalParams() to allow hooks to modify parameters as needed.

Some derived classes may choose to handle an integer $flags parameter in the overriding methods. Callers of this method can pass zero or more OR-ed flags like GET_VALUES_FOR_HELP.

Returns:: array|bool

ApiQueryImageInfo::getCacheMode ( $ params )

Get the cache mode for the data generated by this module.

Override this in the module subclass. For possible return values and other details about cache modes, see ApiMain::setCacheMode()

Public caching will only be allowed if *all* the modules that supply data for a given request return a cache mode of public.

Parameters:

$params

Returns:: string

ApiQueryImageInfo::getContinueStr	(	$	img,
		$	start = `null`
	)		`[protected]`

Parameters:

	$img	File
null \| string	$start

Returns:: string

ApiQueryImageInfo::getDescription ( )

Returns the description string for this module.

Returns:: mixed string or array of strings

ApiQueryImageInfo::getExamples ( )

Returns usage examples for this module.

Return false if no examples are available.

Returns:: bool|string|array

ApiQueryImageInfo::getHelpUrls ( )

Returns:: bool|string|array Returns a false if the module has no help url, else returns a (array of) string

static ApiQueryImageInfo::getInfo	(	$	file,
		$	prop,
		$	result,
		$	thumbParams = `null`,
		$	version = `'latest'`
	)		`[static]`

Get result information for an image revision.

Parameters:

	$file	File object
array	$prop	of properties to get (in the keys)
	$result	ApiResult object
array	$thumbParams	containing 'width' and 'height' items, or null
string	$version	Version of image metadata (for things like jpeg which have different versions).

Returns:: Array: result array

static ApiQueryImageInfo::getProperties ( $ modulePrefix = '' ) [static, private]

Returns array key value pairs of properties and their descriptions.

Parameters:

string $modulePrefix

static ApiQueryImageInfo::getPropertyDescriptions	(	$	filter = `array()`,
		$	modulePrefix = `''`

Returns the descriptions for the properties provided by getPropertyNames()

Parameters:

array	$filter	List of properties to filter out
string	$modulePrefix

Returns:: array

static ApiQueryImageInfo::getPropertyNames ( $ filter = array() ) [static]

Returns all possible parameters to iiprop.

Parameters:

array $filter List of properties to filter out

Returns:: Array

ApiQueryImageInfo::getResultProperties ( )

Returns possible properties in the result, grouped by the value of the prop parameter that shows them.

Properties that are shown always are in a group with empty string as a key. Properties that can be shown by several values of prop are included multiple times. If some properties are part of a list and some are on the root object (see ApiQueryQueryPage), those on the root object are under the key PROP_ROOT. The array can also contain a boolean under the key PROP_LIST, indicating whether the result is a list.

Don't call this function directly: use getFinalResultProperties() to allow hooks to modify descriptions as needed.
