Shared base class for DeserializationContext and SerializerProvider, context objects passed through data-binding process. Designed so that some of implementations can rely on shared aspects like access to secondary contextual objects like type factories or handler instantiators.

Convenience method for constructing subtypes, retaining generic type parameter (if any).

Note

since 2.11 handling has varied a bit across serialization, deserialization.

Convenience method for accessing serialization view in use (if any); equivalent to: 

   getConfig().getAnnotationIntrospector();
getAttributeback to summary
public abstract Object getAttribute(Object key)

Method for accessing attributes available in this context. Per-call attributes have highest precedence; attributes set via ObjectReader or ObjectWriter have lower precedence.

Parameters
key:Object

Key of the attribute to get

Returns:Object

Value of the attribute, if any; null otherwise

invalidTypeIdExceptionback to summary
protected abstract JsonMappingException invalidTypeIdException(JavaType baseType, String typeId, String extraDesc)

Helper method for constructing exception to indicate that given type id could not be resolved to a valid subtype of specified base type. Most commonly called during polymorphic deserialization.

Note that most of the time this method should NOT be called directly: instead, method handleUnknownTypeId() should be called which will call this method if necessary.

Since
2.9
isEnabledback to summary
public abstract boolean isEnabled(MapperFeature feature)

Convenience method for checking whether specified Mapper feature is enabled or not. Shortcut for: 

  getConfig().isEnabled(feature);

resolveAndValidateSubTypeback to summary
public JavaType resolveAndValidateSubType(JavaType baseType, String subClass, PolymorphicTypeValidator ptv) throws JsonMappingException

Lookup method similar to resolveSubType but one that also validates that resulting subtype is valid according to given PolymorphicTypeValidator.

Since
2.10
resolveSubTypeback to summary
public JavaType resolveSubType(JavaType baseType, String subClassName) throws JsonMappingException

Lookup method called when code needs to resolve class name from input; usually simple lookup. Note that unlike resolveAndValidateSubType this method DOES NOT validate subtype against configured PolymorphicTypeValidator: usually because such check has already been made.

Since
2.9
setAttributeback to summary
public abstract DatabindContext setAttribute(Object key, Object value)

Method for setting per-call value of given attribute. This will override any previously defined value for the attribute within this context.

Parameters
key:Object

Key of the attribute to set

value:Object

Value to set attribute to

Returns:DatabindContext

This context object, to allow chaining
