Description

The Append function creates a new array that is the result of combining the base Array followed by the elems. This is a specialized function, and only works with arrays and not pages.

Parameters

Parameter Type Definition and Requirements

elems

Value or Array of Values

The elements to add to the end of the base array.

base

Array

The base array.

Returns

A new Array containing both the base array followed by the elems.

Examples

The following example creates a new array containing the base array’s values, (1, 2, 3), followed by the elems array’s values, (4, 5, 6).

client.query(
  q.Append([4, 5, 6], [1, 2, 3])
)
.then((ret) => console.log(ret))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))
[ 1, 2, 3, 4, 5, 6 ]
result = client.query(
    q.append([4, 5, 6], [1, 2, 3])
)
print(result)
[1, 2, 3, 4, 5, 6]
result, err := client.Query(
	f.Append(f.Arr{4, 5, 6}, f.Arr{1, 2, 3}))

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}
[1 2 3 4 5 6]
try
{
    Value result = await client.Query(
        Append(Arr(4, 5, 6), Arr(1, 2, 3))
    );
    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}
Arr(LongV(1), LongV(2), LongV(3), LongV(4), LongV(5), LongV(6))
System.out.println(
    client.query(
        Append(
            Arr(Value(4), Value(5), Value(6)),
            Arr(Value(1), Value(2), Value(3))
        )
    ).get());
[1, 2, 3, 4, 5, 6]
Append([4, 5, 6], [1, 2, 3])
[ 1, 2, 3, 4, 5, 6 ]
