Interface ConverterBuilder


@ProviderType public interface ConverterBuilder
A builder to create a new converter with modified behavior based on an existing converter. The modified behavior is specified by providing rules and/or conversion functions. If multiple rules match they will be visited in sequence of registration. If a rule's function returns null the next rule found will be visited. If none of the rules can handle the conversion, the original converter will be used to perform the conversion.
