Support for !binary tag

Hi, I have to read yaml files with tags like this: !binary "SSBMaWtlIGJlYW5zIQ==" This tag seems to be YAML standard, a Base64 encoded string. I have already managed to read this as String by insert reader.getConfig().setClassTag("binary", String.class);, and doing a base64 decode later, but the problem is the value on this position is not always Base64 encoded, it’s also a simple string.

Can you add internal support for the !binary tag, or hint me how to write a proper proxy class?

Or a little shorter, use BinarySerializer instead of the BinaryString placeholder:

static public class Test {
	public String s1, s2;

	public String toString () {
		return s1 + ", " + s2;
	}
}

static public class BinarySerializer implements ScalarSerializer<String> {
	public String write (String object) throws YamlException {
		return Base64.getEncoder().encodeToString(object.getBytes());
	}

	public String read (String value) throws YamlException {
		return new String(Base64.getDecoder().decode(value));
	}
}

static public void main (String[] args) throws Exception {
	YamlConfig c = new YamlConfig();
	c.setClassTag("binary", BinarySerializer.class);
	c.setScalarSerializer(BinarySerializer.class, new BinarySerializer());
	YamlReader r = new YamlReader("{ s1: !binary SSBMaWtlIGJlYW5zIQ==, s2: I Like beans! }", c);
	System.out.println(r.read(Test.class));
}

Ah, gotcha. You can do this:

static public class Test {
	public String s1, s2;

	public String toString () {
		return s1 + ", " + s2;
	}
}

static public class BinaryString {
}

static public class BinarySerializer implements ScalarSerializer<String> {
	public String write (String object) throws YamlException {
		return Base64.getEncoder().encodeToString(object.getBytes());
	}

	public String read (String value) throws YamlException {
		return new String(Base64.getDecoder().decode(value));
	}
}

static public void main (String[] args) throws Exception {
	YamlConfig c = new YamlConfig();
	c.setClassTag("binary", BinaryString.class);
	c.setScalarSerializer(BinaryString.class, new BinarySerializer());
	YamlReader r = new YamlReader("{ s1: !binary SSBMaWtlIGJlYW5zIQ==, s2: I Like beans! }", c);
	System.out.println(r.read(Test.class));
}
