Interface ValueConverter

All Superinterfaces:

ConfigurationAware, Converter<Object,String>, Validateable, WithPriority

All Known Implementing Classes:

AbstractValueConverter

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface ValueConverter
extends Converter<Object,String>, WithPriority, Validateable, ConfigurationAware

A value converter can be used to convert an object to a string representation before the value is appended to the result.

Any converter may validate itself - see also Validateable. The validation is performed before a MustacheEngine is built. An invalid converter is not put into service, i.e. it's not included in the final list of converters returned by Configuration.getValueConverters().

This component has also priority - converters with higher priority are called first. When a converter is able to convert the value other components with lower priority are skipped. If no component is able to convert an object, Object.toString() is used.
