Arrays

The asStringArray() method allows you to retrieve comma-delimited lists of values:

key1 = foo, bar, baz

String[] key1 = config.get("key1").asStringArray().orElse(null);

String arrays can also be represented in JSON when the registered parser is a JSON parser:

key1 = ['foo','bar','baz']

String[] key1 = config.get("key1").asStringArray().orElse(null);

Primitive arrays can also be retrieved using the as() and to() methods:

key1 = [1,2,3]

int[] key1 = config.get("key1").as(int[].class).orElse(null);

Arrays of POJOs can also be retrieved using the methods as well:

addresses =
    [
        {
            street: '123 Main Street',
            city: 'Anywhere',
            state: 'NY',
            zip: 12345
        },
        {
            street: '456 Main Street',
            city: 'Anywhere',
            state: 'NY',
            zip: 12345
        }
    ]

Address[] addresses = config.get("addresses").as(Address[].class).orElse(null);
