edu.internet2.middleware.grouperClientExt.com.fasterxml.jackson.databind.DatabindContext

Direct Known Subclasses:

DeserializationContext, SerializerProvider

public abstract class DatabindContext
extends Object

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.

Constructor Details

DatabindContext

public DatabindContext()

Method Details

getConfig

public abstract MapperConfig<?> getConfig()

Accessor to currently active configuration (both per-request configs and per-mapper config).

getAnnotationIntrospector

public abstract AnnotationIntrospector getAnnotationIntrospector()

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

   getConfig().getAnnotationIntrospector();

isEnabled

public abstract boolean isEnabled(MapperFeature feature)

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

  getConfig().isEnabled(feature);

isEnabled

public abstract boolean isEnabled(DatatypeFeature feature)

Method for checking whether specified datatype feature is enabled or not.

Since:

2.14

canOverrideAccessModifiers

public abstract boolean canOverrideAccessModifiers()

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

   getConfig().canOverrideAccessModifiers();

getActiveView

public abstract Class<?> getActiveView()

Accessor for locating currently active view, if any; returns null if no view has been set.

getLocale

public abstract Locale getLocale()

Since:

2.6

getTimeZone

public abstract TimeZone getTimeZone()

Since:

2.6

getDefaultPropertyFormat

public abstract JsonFormat.Value getDefaultPropertyFormat(Class<?> baseType)

Since:

2.7

getAttribute

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 - Key of the attribute to get

Returns:

Value of the attribute, if any; null otherwise

Since:

2.3

setAttribute

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 - Key of the attribute to set

value - Value to set attribute to

Returns:

This context object, to allow chaining

Since:

2.3

constructType

public JavaType constructType(Type type)

Convenience method for constructing JavaType for given JDK type (usually Class)

constructSpecializedType

public abstract JavaType constructSpecializedType(JavaType baseType,
 Class<?> subclass)

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

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

resolveSubType

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(edu.internet2.middleware.grouperClientExt.com.fasterxml.jackson.databind.JavaType, java.lang.String, edu.internet2.middleware.grouperClientExt.com.fasterxml.jackson.databind.jsontype.PolymorphicTypeValidator) this method DOES NOT validate subtype against configured PolymorphicTypeValidator: usually because such check has already been made.

Throws:

JsonMappingException

Since:

2.9

resolveAndValidateSubType

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

Lookup method similar to resolveSubType(edu.internet2.middleware.grouperClientExt.com.fasterxml.jackson.databind.JavaType, java.lang.String) but one that also validates that resulting subtype is valid according to given PolymorphicTypeValidator.

Throws:

JsonMappingException

Since:

2.10

_throwNotASubtype

protected <T> T _throwNotASubtype(JavaType baseType,
 String subType)
                           throws JsonMappingException

Throws:

JsonMappingException

_throwSubtypeNameNotAllowed

protected <T> T _throwSubtypeNameNotAllowed(JavaType baseType,
 String subType,
 PolymorphicTypeValidator ptv)
                                     throws JsonMappingException

Throws:

JsonMappingException

_throwSubtypeClassNotAllowed

protected <T> T _throwSubtypeClassNotAllowed(JavaType baseType,
 String subType,
 PolymorphicTypeValidator ptv)
                                      throws JsonMappingException

Throws:

JsonMappingException

invalidTypeIdException

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

getTypeFactory

public abstract TypeFactory getTypeFactory()

objectIdGeneratorInstance

public ObjectIdGenerator<?> objectIdGeneratorInstance(Annotated annotated,
 ObjectIdInfo objectIdInfo)
                                               throws JsonMappingException

Throws:

JsonMappingException

objectIdResolverInstance

public ObjectIdResolver objectIdResolverInstance(Annotated annotated,
 ObjectIdInfo objectIdInfo)

converterInstance

public Converter<Object,Object> converterInstance(Annotated annotated,
 Object converterDef)
                                           throws JsonMappingException

Helper method to use to construct a Converter, given a definition that may be either actual converter instance, or Class for instantiating one.

Throws:

JsonMappingException

Since:

2.2

reportBadDefinition

public abstract <T> T reportBadDefinition(JavaType type,
 String msg)
                                   throws JsonMappingException
