Specified by:

version in interface Versioned

Since:

1.6

Method for disabling specified feature.

set

public void set(AbstractTypeMaterializer.Feature f,
       boolean state)

resolveAbstractType

public JavaType resolveAbstractType(DeserializationConfig config,
                           JavaType type)

Description copied from class: AbstractTypeResolver

Method called to try to resolve an abstract type into concrete type (usually for purposes of deserializing), when no concrete implementation was found. It will be called after checking all other possibilities, including defaulting.

Overrides:

resolveAbstractType in class AbstractTypeResolver

Parameters:

config - Configuration in use; should always be of type DeserializationConfig

type - Type for which materialization maybe needed

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

materializeClass

protected Class<?> materializeClass(DeserializationConfig config,
                        Class<?> cls)
