com.fasterxml.jackson.databind.type.TypeModifier

public abstract class TypeModifier
extends Object

Class that defines API that can be used to modify details of JavaType instances constructed using TypeFactory. Registered modifiers are called in order, to let them modify (or replace) basic type instance factory constructs. This is typically needed to support creation of MapLikeType and CollectionLikeType instances, as those cannot be constructed in generic fashion.

modifyType

public abstract JavaType modifyType(JavaType type,
                                    Type jdkType,
                                    TypeBindings context,
                                    TypeFactory typeFactory)

Method called to let modifier change constructed type definition. Note that this is only guaranteed to be called for non-container types ("simple" types not recognized as arrays, java.util.Collection or java.util.Map).

Parameters:

type - Instance to modify

jdkType - JDK type that was used to construct instance to modify

context - Type resolution context used for the type

typeFactory - Type factory that can be used to construct parameter type; note, however, that care must be taken to avoid infinite loops -- specifically, do not construct instance of primary type itself

Returns:

Actual type instance to use; usually either type (as is or with modifications), or a newly constructed type instance based on it. Cannot be null.
