public static function EntityFieldHandlerHelper::get_value in Entity API 7

Get the value of a certain data selector.

Uses $values->_entity_properties to look for already extracted properties.

Parameters

$handler: The field handler for which to return a value.

$values: The values for the current row retrieved from the Views query, as an object.

$field: The field to extract. If no value is given, the field of the given handler is used instead. The special "entity object" value can be used to get the base entity instead of a special field.

$default: The value to return if the entity or field are not present.
