Retrieves entities matching a given set of conditions.

This class allows finding entities based on entity properties (for example, node->changed), field values, and generic entity meta data (bundle, entity type, entity ID, and revision ID). It is not possible to query across multiple entity types. For example, there is no facility to find published nodes written by users created in the last hour, as this would require querying both node->status and user->created.

Normally we would not want public properties on the object, as that could allow the object's state to become inconsistent. However, this class's standard use case involves primarily code that does need to have direct access to the collected properties in order to handle alternate execution routines. We therefore use public properties for simplicity. Note that code that is creating and running a field query should still use the appropriate methods to add conditions on the query.

Storage engines are not required to support every type of query. By default, an EntityFieldQueryException will be raised if an unsupported condition is specified or if the query has field conditions or sorts that are stored in different field storage engines. However, this logic can be overridden in hook_entity_query_alter().

Also note that this query does not automatically respect entity access restrictions. Node access control is performed by the SQL storage engine but other storage engines might not do this.
