accept

 final <T extends Any> T accept(SendMessageParams.Message.To.Recipient.Visitor<T> visitor)

Maps this instance's current variant to a value of type T using the given visitor.

Note that this method is not forwards compatible with new variants from the API, unless visitor overrides Visitor.unknown. To handle variants not known to this version of the SDK gracefully, consider overriding Visitor.unknown:

import com.courier.core.JsonValue;
import java.util.Optional;

Optional<String> result = recipient.accept(new Recipient.Visitor<Optional<String>>() {
    @Override
    public Optional<String> visitUser(UserRecipient user) {
        return Optional.of(user.toString());
    }

    // ...

    @Override
    public Optional<String> unknown(JsonValue json) {
        // Or inspect the `json`.
        return Optional.empty();
    }
});

validate
```
 final SendMessageParams.Message.To.Recipient validate()
```
Validates that the types of all values in this object match their expected types recursively.
This method is not forwards compatible with new types from the API for existing fields.

isValid
```
 final Boolean isValid()
```

equals
```
 Boolean equals(Object other)
```

hashCode
```
 Integer hashCode()
```

toString
```
 String toString()
```
