isFlat

The isFlat method returns a boolean value that is true if the table is flat, or false if it is not.

Syntax​

source.isFlat()

Parameters​

This method takes no arguments.

Returns​

A boolean value that is true if the table is flat or false if it is not.

Example​

In this example we create a time table and a result table that has an aggregation. Next, we call isFlat twice to see which of the tables is flat.

import static io.deephaven.api.agg.Aggregation.AggFirst

tt = timeTable("PT1S").update("X = ii")

result = tt.aggBy([AggFirst("Timestamp")], "X")

println tt.isFlat()
println result.isFlat()
