Example 1 with JsonStringFormatVisitor

use of com.fasterxml.jackson.databind.jsonFormatVisitors.JsonStringFormatVisitor in project jackson-databind by FasterXML.

the class EnumSerializer method acceptJsonFormatVisitor.

@Override
public void acceptJsonFormatVisitor(JsonFormatVisitorWrapper visitor, JavaType typeHint) throws JsonMappingException {
    SerializerProvider serializers = visitor.getProvider();
    if (_serializeAsIndex(serializers)) {
        visitIntFormat(visitor, typeHint, JsonParser.NumberType.INT);
        return;
    }
    JsonStringFormatVisitor stringVisitor = visitor.expectStringFormat(typeHint);
    if (stringVisitor != null) {
        Set<String> enums = new LinkedHashSet<String>();
        // Use toString()?
        if ((serializers != null) && serializers.isEnabled(SerializationFeature.WRITE_ENUMS_USING_TO_STRING)) {
            for (Enum<?> e : _values.enums()) {
                enums.add(e.toString());
            }
        } else {
            // No, serialize using name() or explicit overrides
            for (SerializableString value : _values.values()) {

            }
        }
        stringVisitor.enumTypes(enums);
    }
}
