Creates a specification that retrieve tasks that match filters in the request without restrictions related to any user.

Parameters:

taskSearchRequest - the request containing all the filters

Returns:

a specification that applies the filters in the request

restricted

public static TaskSpecification restricted(TaskSearchRequest taskSearchRequest,
 String userId,
 Collection<String> userGroups)

Creates a specification that applies the filters and restricts the retrieved tasks based on the given user and groups.

Parameters:

taskSearchRequest - the request containing all the filters

userId - user id to be applied for restriction

userGroups - groups to be applied for restriction

Returns:

a specification that applies the filters and restricts the retrieved tasks based on the given user and groups
