Returns the value of a scalar query as a T in a blocking fashion. The result may be of a different type depending on the type of query:

fun <T, R> RealmScalarNullableQuery<T>.find(block: (T?) -> R): R

Similar to RealmScalarNullableQuery.find but it receives a block in which the scalar result from the query is provided.

fun <T, R> RealmScalarQuery<T>.find(block: (T) -> R): R

Similar to RealmScalarQuery.find but it receives a block in which the scalar result from the query is provided.
