Interface ValueDeserializerProvider<T,R>

Type Parameters:

T - type of the config values to deserialize

R - resulting type of the deserialization of these values

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 ValueDeserializerProvider<T,R>

Provides ValueDeserializer to deserialize configuration values.

The provide(Class, TypeConstraint) method returns null when it cannot provide a deserializer for the given value type and result type. In that case, other providers will be called, until a suitable deserializer is found or all the providers have been tried.

Method Summary

Modifier and Type	Method and Description
ValueDeserializer<T,R>	provide(java.lang.Class<?> valueClass, TypeConstraint resultType) Provides a deserializer for a value of class valueClass and a constraint on the result type.

Method Detail

provide

ValueDeserializer<T,R> provide(java.lang.Class<?> valueClass,
                               TypeConstraint resultType)

Provides a deserializer for a value of class valueClass and a constraint on the result type. The returned deserializer must be able to handle a value of this type and to produce a value that satisfies the resultType constraint.

Parameters:

valueClass - class of the config values to deserialize

resultType - constraint that the deserialization result must satisfy

Returns:

a deserializer, or null to try the next provider
