the class RelationshipRowCallbackHandler method createItem.

/**
 * The SQL query that generates the ResultSet used by this
 * {@see RowCallbackHandler} fetches both sides of a relationship: since
 * each side can be a Tracked Entity Instance, a Program Instance or a
 * Program Stage Instance, the query adds an "hint" to the final result to
 * help this Handler to correctly associate the type to the left or right
 * side of the relationship. The "typeWithUid" variable contains the UID of
 * the object and a string representing the type. E.g.
 *
 * tei|dj3382832 psi|332983893
 *
 * This function parses the string and extract the type and the uid, in
 * order to instantiate the appropriate object and assign it to the
 * {@see RelationshipItem}
 *
 * @param typeWithUid a String containing the object type and the UID of the
 *        object, separated by | (pipe)
 * @return a {@see RelationshipItem}
