For record ID ranges used in CRUD operations (select, update, delete), see RecordIdRange.

.getRangeStart()
Returns the start bound of the range, if present.
Method Syntax
value.getRangeStart()

.getRangeEnd()

Method Syntax
value.getRangeEnd()

Example
Working with range values
import com.surrealdb.Surreal;
import com.surrealdb.Response;
import com.surrealdb.Value;
import com.surrealdb.signin.RootCredential;
try (Surreal db = new Surreal()) {
db.connect("ws://localhost:8000");
db.useNs("surrealdb").useDb("docs");
db.signin(new RootCredential("root", "root"));
Response response = db.query("RETURN 1..10");
Value result = response.take(0);
if (result.isRange()) {
Optional<Value> start = result.getRangeStart();
Optional<Value> end = result.getRangeEnd();
}
}
