public abstract class TypeModifier extends Object
Class that defines API that can be used to modify details ofJavaType
instances constructed usingTypeFactory
. Registered modifiers are called in order, to let them modify (or replace) basic type instance factory constructs. This is typically needed to support creation ofMapLikeType
andCollectionLikeType
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
orjava.util.Map
).- Parameters:
type
- Instance to modifyjdkType
- JDK type that was used to construct instance to modifycontext
- Type resolution context used for the typetypeFactory
- 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.
