Public Member Functions

evaluate (stdClass $row, $value)

Evaluate the filter condition against a row, determining whether it is true or false.Ignore the values set with require() and exclude(), use only the value passed as a parameter.To ensure that $row has the required fields present, capture() must be called before evaluate(). This will signal to prepareQuery() that the fields should be added.

Parameters

stdClass	$row
mixed	$value	The validated value

Returns: bool

validateValue ( $value)

Validate a value and return its normalized form.

Parameters

mixed $value

Returns: mixed

exclude ( $value)

Add a value to the set of excluded values.

prepareQuery (IReadableDatabase $dbr, QueryBackend $query)

Add conditions and joins to the query in order to implement require() and exclude().

Protected Member Functions

prepareCapture (IReadableDatabase $dbr, QueryBackend $query)

prepareConds (IReadableDatabase $dbr, QueryBackend $query)

Add conditions to the query according to the values passed to require() and exclude().Subclasses may use getUniqueValuesWithUnion() to get the required and excluded values.

Parameters
