All Known Implementing Classes:

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 ConversionFinder
A pluggable strategy for discovering Conversion functions between type pairs.

Implementations are passed to the ConfigurableConverter constructor and are consulted in order before the built-in BasicConverter reflection logic.

Return null from findConversion(Class, Class) to indicate that this finder has no conversion for the given type pair; the next registered finder (or the built-in logic) will be tried instead.

Example:

ConfigurableConverter converter = new ConfigurableConverter( (inType, outType) -> { if (inType == String.class && outType == MyBean.class) return (in, memberOf, session, args) -> MyBean.fromString((String) in); return null; } );
