2. 2.0.x modules/leaflet_views/src/Plugin/views/style/MarkerLayerGroup.php \Drupal\leaflet_views\Plugin\views\style\MarkerLayerGroup::renderGrouping()

Group records as needed for rendering.

Parameters

$records: An array of records from the view to group.

$groupings: An array of grouping instructions on which fields to group. If empty, the result set will be given a single group with an empty string as a label.

$group_rendered: Boolean value whether to use the rendered or the raw field value for grouping. If set to NULL the return is structured as before Views 7.x-3.0-rc2. After Views 7.x-3.0 this boolean is only used if $groupings is an old-style string or if the rendered option is missing for a grouping instruction.

Return value

The grouped record set. A nested set structure is generated if multiple grouping fields are used.

array(
  'grouping_field_1:grouping_1' => array(
    'group' => 'grouping_field_1:content_1',
    'level' => 0,
    'rows' => array(
      'grouping_field_2:grouping_a' => array(
        'group' => 'grouping_field_2:content_a',
        'level' => 1,
        'rows' => array(
          $row_index_1 => $row_1,
          $row_index_2 => $row_2,
        ),
