Supplier<T> (Interface)
Use Case
Implementation of this interface are used to extract a channel value of interest from a MRecord.
Lambda example implementations
Simple example on a Boolean channel
Supplier<Boolean> supplier = (Supplier<Boolean>)(values) -> values.getBoolean("flag");
In this case the supplier implementation is extracting the Boolean channel value with the name “flag”.
Example on a Double channel
Supplier<Double> supplier = (Supplier<Double>)(values) -> values.getDouble("U");
In this case the supplier implementation is extracting the Double channel value with the name “U”.
Example on two values at once
Supplier<Tuple2<Double, Boolean>> supplier = (Supplier<Tuple2<Double, Boolean>>)
(values) -> new Tuple2(values.getBoolean("flag"), values.getDouble("U"));
In this case the supplier implementation is extraction the both values from the previous examples at once. It also could have returned a List or similar.
