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

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.
