public abstract class DatabindContext
extends java.lang.Object
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.Constructor and Description |

DatabindContext() |
Modifier and Type | Method and Description |
---|---|
abstract boolean |
canOverrideAccessModifiers()
Convenience method for accessing serialization view in use (if any); equivalent to:
|
JavaType |
constructSpecializedType(JavaType baseType,
java.lang.Class<?> subclass)
Convenience method for constructing subtypes, retaining generic
type parameter (if any)
|
JavaType |
constructType(java.lang.reflect.Type type)
Convenience method for constructing
JavaType for given JDK
type (usually Class ) |
Converter<java.lang.Object,java.lang.Object> |
converterInstance(Annotated annotated,
java.lang.Object converterDef)
Helper method to use to construct a
Converter , given a definition
that may be either actual converter instance, or Class for instantiating one. |
abstract java.lang.Class<?> |
getActiveView()
Accessor for locating currently active view, if any;
returns null if no view has been set.
|
abstract AnnotationIntrospector |
getAnnotationIntrospector()
Convenience method for accessing serialization view in use (if any); equivalent to:
|
abstract java.lang.Object |
getAttribute(java.lang.Object key)
Method for accessing attributes available in this context.
|
abstract MapperConfig<?> |
getConfig()
Accessor to currently active configuration (both per-request configs
and per-mapper config).
|
abstract JsonFormat.Value |
getDefaultPropertyFormat(java.lang.Class<?> baseType) |
abstract java.util.Locale |
getLocale() |
abstract java.util.TimeZone |
getTimeZone() |
abstract TypeFactory |
getTypeFactory() |
abstract boolean |
isEnabled(MapperFeature feature)
Convenience method for checking whether specified serialization
feature is enabled or not.
|
ObjectIdGenerator<?> |
objectIdGeneratorInstance(Annotated annotated,
ObjectIdInfo objectIdInfo) |
ObjectIdResolver |
objectIdResolverInstance(Annotated annotated,
ObjectIdInfo objectIdInfo) |
<T> T |
reportBadDefinition(java.lang.Class<?> type,
java.lang.String msg) |
abstract <T> T |
reportBadDefinition(JavaType type,
java.lang.String msg)
Helper method called to indicate a generic problem that stems from type
definition(s), not input data, or input/output state; typically this
means throwing a
InvalidDefinitionException . |
JavaType |
resolveAndValidateSubType(JavaType baseType,
java.lang.String subClass,
PolymorphicTypeValidator ptv)
Lookup method similar to
resolveSubType(com.fasterxml.jackson.databind.JavaType, java.lang.String) but one that also validates
that resulting subtype is valid according to given PolymorphicTypeValidator . |
JavaType |
resolveSubType(JavaType baseType,
java.lang.String subClassName)
Lookup method called when code needs to resolve class name from input;
usually simple lookup.
|
abstract DatabindContext |
setAttribute(java.lang.Object key,
java.lang.Object value)
Method for setting per-call value of given attribute.
