◆ __construct()

ApiFormatBase::__construct	(	$main,
		$format
	)

Constructor If $format ends with 'fm', pretty-print the output in HTML.

string	$format	Format name

Reimplemented in ApiFormatJson, and ApiFormatRaw.

Definition at line 42 of file ApiFormatBase.php.

Member Function Documentation

◆ canPrintErrors()

ApiFormatBase::canPrintErrors ( )

Whether this formatter can handle printing API errors.

If this returns false, then on API errors the default printer will be instantiated.

Since: 1.23

Returns: bool

Reimplemented in ApiFormatFeedWrapper.

Definition at line 129 of file ApiFormatBase.php.

◆ closePrinter()

else ApiFormatBase::closePrinter ( )

Finish printing.

Closes HTML tags.

Definition at line 209 of file ApiFormatBase.php.

References getIsHtml(), php, and pre.

◆ disable()

ApiFormatBase::disable ( )

Disable the formatter completely.

This causes calls to initPrinter(), printText() and closePrinter() to be ignored.

Definition at line 115 of file ApiFormatBase.php.

◆ formatHTML()

ApiFormatBase::formatHTML ( $text )

protected

Pretty-print various elements in HTML format, such as xml tags and URLs.

This method also escapes characters like <

Parameters

$text string

Returns: string

◆ getBuffer()

ApiFormatBase::getBuffer ( )

Get the contents of the buffer.

Definition at line 252 of file ApiFormatBase.php.

References $mBuffer.

◆ getDescription()

ApiFormatBase::getDescription ( )

Returns the description string for this module.

Returns: mixed string or array of strings

Reimplemented from ApiBase.

Reimplemented in ApiFormatJson, ApiFormatDump, ApiFormatDbg, ApiFormatTxt, ApiFormatPhp, ApiFormatNone, and ApiFormatYaml.

Definition at line 339 of file ApiFormatBase.php.

References getIsHtml().

Referenced by ApiFormatYaml\getDescription().

◆ getExamples()

ApiFormatBase::getExamples ( )

Returns usage examples for this module.

Return false if no examples are available.

Returns: bool|string|array

Reimplemented from ApiBase.

Definition at line 328 of file ApiFormatBase.php.

References array(), and ApiBase\getModuleName().

◆ getFormat()

ApiFormatBase::getFormat ( )

Get the internal format name.

Returns: string

Definition at line 74 of file ApiFormatBase.php.

References $mFormat.

◆ getHelpUrls()

ApiFormatBase::getHelpUrls ( )

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

Reimplemented from ApiBase.

Definition at line 335 of file ApiFormatBase.php.

◆ getIsHtml()

ApiFormatBase::getIsHtml ( )

Returns true when the HTML pretty-printer should be used.

The default implementation assumes that formats ending with 'fm' should be formatted in HTML.

Returns: bool

Definition at line 97 of file ApiFormatBase.php.

References $mIsHtml.

Referenced by closePrinter(), ApiFormatJson\execute(), getDescription(), getWantsHelp(), initPrinter(), and printText().

◆ getMimeType()

ApiFormatBase::getMimeType ( )

abstract

Overriding class returns the mime type that should be sent to the client.

This method is not called if getIsHtml() returns true.

Returns: string

Reimplemented in ApiFormatFeedWrapper, ApiFormatRaw, ApiFormatJson, ApiFormatDbg, ApiFormatDump, ApiFormatNone, ApiFormatPhp, ApiFormatTxt, and ApiFormatYaml.

Referenced by initPrinter().

◆ getNeedsRawData()

ApiFormatBase::getNeedsRawData ( )

Whether this formatter needs raw data such as _element tags.

Returns: bool

Reimplemented in ApiFormatFeedWrapper, and ApiFormatJson.

Definition at line 66 of file ApiFormatBase.php.

◆ getWantsHelp()

ApiFormatBase::getWantsHelp ( )

Whether this formatter can format the help message in a nice way.

By default, this returns the same as getIsHtml(). When action=help is set explicitly, the help will always be shown

Returns: bool

Reimplemented in ApiFormatJson.

Definition at line 107 of file ApiFormatBase.php.

References getIsHtml().

◆ initPrinter()

ApiFormatBase::initPrinter ( $isHelpScreen )

Initialize the printer function and prepare the output headers, etc.

This method must be the first outputting method during execution. A human-targeted notice about available formats is printed for the HTML-based output, except for help screens (caused by either an error in the API parameters, the calling of action=help, or requesting the root script api.php).

Parameters

bool $isHelpScreen Whether a help screen is going to be shown

◆ isDisabled()

ApiFormatBase::isDisabled ( )

Definition at line 119 of file ApiFormatBase.php.

References $mDisabled.

◆ printText()

ApiFormatBase::printText ( $text )

The main format printing function.

Call it to output the result string to the user. This function will automatically output HTML when format name ends in 'fm'.

Parameters

$text string

Definition at line 229 of file ApiFormatBase.php.

References formatHTML(), and getIsHtml().

Referenced by ApiFormatPhp\execute(), ApiFormatDbg\execute(), ApiFormatDump\execute(), ApiFormatTxt\execute(), ApiFormatRaw\execute(), and ApiFormatJson\execute().

◆ setBufferResult()

ApiFormatBase::setBufferResult ( $value )

Set the flag to buffer the result instead of printing it.

Parameters

$value bool

Definition at line 260 of file ApiFormatBase.php.

References $value.

◆ setHelp()

ApiFormatBase::setHelp ( $help = true )

Sets whether the pretty-printer should format bold

Parameters

$help bool

Definition at line 268 of file ApiFormatBase.php.

References $help.

◆ setUnescapeAmps()

ApiFormatBase::setUnescapeAmps ( $b )

Specify whether or not sequences like " should be unescaped to " .

This should only be set to true for the help message when rendered in the default (xmlfm) format. This is a temporary special-case fix that should be removed once the help has been reworked to use a fully HTML interface.

Parameters

bool $b Whether or not ampersands should be escaped.
