static class

AbstractTypeMaterializer.Feature Enumeration that defines togglable features that guide the serialization feature.

Method Summary

void	disable(AbstractTypeMaterializer.Feature f) Method for disabling specified feature.

Description copied from class: AbstractTypeResolver

Method called to try to resolve an abstract type into concrete type, usually for purposes of deserializing.

Specified by:

resolveAbstractType in class AbstractTypeResolver

Parameters:

config - Deserialization configuration in use

type - Abstract type (with generic type parameters if any) to resolve

Returns:

Resolved concrete type (which should retain generic type parameters of input type, if any), if resolution succeeds; null if resolver does not know how to resolve type
