awaitUpdate
The awaitUpdate method instructs Deephaven to wait for updates to the table specified in the query.
Syntax
table.awaitUpdate()
table.awaitUpdate(timeout)
Parameters
| Parameter | Type | Description |
|---|---|---|
| timeout | long | The maximum time to wait, in milliseconds. |
Returns
A boolean value - false if the timeout elapses without notification, true otherwise.
Examples
In this example, the result of awaitUpdate is called and printed twice. The first time, 1 milliseconds have elapsed, and the method returns false since the table has not been updated. awaitUpdate is called again immediately afterward with a wait time of 1000 milliseconds. By that time, the source table has been updated, so the method returns true.
source = timeTable("PT00:00:01")
println(source.awaitUpdate(1))
println(source.awaitUpdate(1000))
result = source.update(formulas=("renamedTimestamp = Timestamp"))
