Class DatabindContext

java.lang.Object

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.

Since:

2.2

Methods

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, Class<?> subclass) Convenience method for constructing subtypes, retaining generic type parameter (if any)
JavaType	constructType(Type type) Convenience method for constructing JavaType for given JDK type (usually Class)
Converter<Object,Object>	converterInstance(Annotated annotated, 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 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 Object	getAttribute(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(Class<?> baseType)
abstract Locale	getLocale()
abstract 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)
abstract DatabindContext	setAttribute(Object key, Object value) Method for setting per-call value of given attribute.

public DatabindContext()

Method Detail

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 serialization feature is enabled or not. Shortcut for:

  getConfig().isEnabled(feature);

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

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

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
