Package org.apache.juneau.commons.conversion

Interface Conversion<I,O>

Type Parameters:
I - The input type.
O - The output type.
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 Conversion<I,O>
Functional interface representing a single type conversion used by CachingConverter.

The args parameter carries any type arguments needed for parameterized output types. For example, when converting to a List, args[0] would be the element type. For a Map, args[0] is the key type and args[1] is the value type.

A single cached Conversion function can serve all parameterizations of the same raw output type by accepting different args values at runtime.
