Argument Type Definition and Requirements

A single Boolean value.

Returns

A Boolean value.

Examples

The following query returns false because an argument of "true" is provided:

try
{
    Value result = await client.Query(
        Not(true)
    );
    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}
BooleanV(False)
result, err := client.Query(
	f.Not(true))

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}
false
System.out.println(
    client.query(
        Not(Value(true))
    ).get());
false
client.query(
  q.Not(true)
)
.then((ret) => console.log(ret))
.catch((err) => console.error('Error: %s', err))
false
result = client.query(
  q.not_(True)
)
print(result)
False
try {
  println(Await.result(
    client.query(Not(true)),
    5.seconds
  ))
} catch {
  case unknown: Throwable => println("Error: " + unknown.getMessage())
}
false
