Member Function Documentation

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

ApiFormatBase::disable ( )

Disable the formatter.

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

ApiFormatBase::forceDefaultParams ( )

Ignore request parameters, force a default.

Used as a fallback if errors are being thrown.

Since
1.26

ApiFormatBase::getIsWrappedHtml ( )
protected

Returns true when the special wrapped mode is enabled.

Since
1.27
Returns
bool

Definition at line 89 of file ApiFormatBase.php.

References $mIsWrappedHtml.

Referenced by closePrinter(), and initPrinter().

ApiFormatBase::getMimeType ( )
abstract

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

When getIsHtml() returns true, the return value here is used for syntax highlighting but the client sees text/html.

Returns
string

Referenced by closePrinter(), and initPrinter().

ApiFormatBase::getParameterFromSettings (   $paramName,
  $paramSettings,
  $parseLimit 
)
protected

Overridden to honor $this->forceDefaultParams(), if applicable.

Since
1.26

Definition at line 136 of file ApiFormatBase.php.

ApiFormatBase::initPrinter (   $unused = false)

Initialize the printer function and prepare the output headers.

Parameters
bool$unusedAlways false since 1.25

Returns
bool
