◆ __construct()

ChangesListFilterGroup::__construct ( array $groupDefinition )

Create a new filter group with the specified configuration.

Parameters

array

$groupDefinition

Configuration of group

$groupDefinition['name'] string Group name; use camelCase with no punctuation
$groupDefinition['title'] string i18n key for title (optional, can be omitted only if none of the filters in the group display in the structured UI)
$groupDefinition['type'] string A type constant from a subclass of this one
$groupDefinition['priority'] int Priority integer. Higher value means higher up in the group list (optional, defaults to -100).
$groupDefinition['filters'] array Numeric array of filter definitions, each of which is an associative array to be passed to the filter constructor. However, 'priority' is optional for the filters. Any filter that has priority unset will be put to the bottom, in the order given.
$groupDefinition['isFullCoverage'] bool Whether the group is full coverage; if true, this means that checking every item in the group means no changes list entries are filtered out.
$groupDefinition['whatsThisHeader'] string i18n key for header of "What's This" popup (optional).
$groupDefinition['whatsThisBody'] string i18n key for body of "What's This" popup (optional).

◆ conflictsWith()

ChangesListFilterGroup::conflictsWith	(	$other,
