ReQL command: for
Command syntax
for (doc : <Cursor>) { ... }
Description
Lazily iterate over a result set one element at a time.
RethinkDB cursors can be iterated through via the Java Iterable and Iterator interfaces; use standard Java commands like for
loops to access each item in the sequence.
Example: Let’s process all the elements!
Cursor cursor = r.table("users").run(conn); for (Object doc : cursor) { System.out.println(doc); }
Example: Stop the iteration prematurely and close the connection manually.
Cursor cursor = r.table("users").run(conn); for (Object doc: cursor) { ok = processRow(doc); if (ok == false) { cursor.close(); break; } }
