//
// (1) Uri - query has not been executed yet
//
// (2) CallerInfoToken - query is executing, but has not completed.
//
// (3) CallerInfo - query has executed.
//
// In each case we have slightly different behaviour:
// 1. If the query has not been executed yet (Uri or null), we start
// query execution asynchronously, and note it by attaching a
// CallerInfoToken as the userData.
// 2. If the query is executing (CallerInfoToken), we've essentially
// reached a state where we've received multiple requests for the
// same callerInfo. That means that once the query is complete,
// we'll need to execute the additional listener requested.
// 3. If the query has already been executed (CallerInfo), we just
// return the CallerInfo object as expected.
// 4. Regarding isFinal - there are cases where the CallerInfo object
// will not be attached, like when the number is empty (caller id
// blocking). This flag is used to indicate that the
// CallerInfoToken object is going to be permanent since no
// query results will be returned. In the case where a query
// has been completed, this flag is used to indicate to the caller
// that the data will not be updated since it is valid.
//
// Note: For the case where a number is NOT retrievable, we leave
// the CallerInfo as null in the CallerInfoToken. This is
// something of a departure from the original code, since the old
// code manufactured a CallerInfo object regardless of the query
// outcome. From now on, we will append an empty CallerInfo
// object, to mirror previous behaviour, and to avoid Null Pointer
