TypeConverter

Type converter is used to convert value based only on the value itself.

Converter should be registered when you create a tracker by calling createExampleTracker { addConverter(TypeConverterImpl()) }.

Type converters are called at second stage of value conversion, after parameter converters. Conversion process goes on until one of converters return not-null value or all converters at both stages are out.

Converters are called by trckr in order in which they are were added. So you should make sure more general converters were added after more specific ones.

Example converter:

class EnumConverter : TypeConverter {

    fun convert(value: Any?): Any? {
        return if (value is Enum<*>) value.name else null
    }
}
