Module.SetupContext (jackson-databind 2.6.0 API)

Enclosing class:

Module
```
public static interface Module.SetupContext
```
Interface Jackson exposes to modules for purpose of registering extended functionality. Usually implemented by ObjectMapper, but modules should NOT rely on this -- if they do require access to mapper instance, they need to call getOwner() method.

- Method Detail
  - getMapperVersion
```
com.fasterxml.jackson.core.Version getMapperVersion()
```
    Method that returns version information about ObjectMapper that implements this context. Modules can use this to choose different settings or initialization order; or even decide to fail set up completely if version is compatible with module.
  - getOwner
```
<C extends com.fasterxml.jackson.core.ObjectCodec> C getOwner()
```
    Fallback access method that allows modules to refer to the ObjectMapper that provided this context. It should NOT be needed by most modules; and ideally should not be used -- however, there may be cases where this may be necessary due to various design constraints.
    NOTE: use of this method is discouraged, as it allows access to things Modules typically should not modify. It is included, however, to allow access to new features in cases where Module API has not yet been extended, or there are oversights.
    Return value is chosen to not leak dependency to ObjectMapper; however, instance will always be of that type. This is why return value is declared generic, to allow caller to specify context to often avoid casting.

    2.0
  - getTypeFactory
```
TypeFactory getTypeFactory()
```
    Accessor for finding TypeFactory that is currently configured by the context.
    NOTE: since it is possible that other modules might change or replace TypeFactory, use of this method adds order-dependency for registrations.

    Parameters:
    
    ai - Annotation introspector to register.

void registerSubtypes(Class<?>... subtypes)
```
    Method for registering specified classes as subtypes (of supertype(s) they have)

void setMixInAnnotations(Class<?> target,

```
    Method used for defining mix-in annotations to use for augmenting specified class or interface. All annotations from mixinSource are taken to override annotations that target (or its supertypes) has.
    Note: mix-ins are registered both for serialization and deserialization (which can be different internally).
    Note: currently only one set of mix-in annotations can be defined for a single class; so if multiple modules register mix-ins, highest priority one (last one registered) will have priority over other modules.
    
    Parameters:
    
    target - Class (or interface) whose annotations to effectively override
    
    mixinSource - Class (or interface) whose annotations are to be "added" to target's annotations, overriding as necessary
  - addDeserializationProblemHandler

void addDeserializationProblemHandler(DeserializationProblemHandler handler)

    Parameters:
    
    handler - The deserialization problem handler
  - setNamingStrategy
```
void setNamingStrategy(PropertyNamingStrategy naming)
```
    Method that may be used to override naming strategy that is used by ObjectMapper.
