tools.jackson.databind.ValueSerializer<Object>

tools.jackson.databind.ser.std.StdSerializer<Object>

tools.jackson.databind.ser.std.AsArraySerializerBase<Object>

tools.jackson.databind.ser.jdk.IndexedListSerializer

All Implemented Interfaces:

JsonFormatVisitable

public final class IndexedListSerializer
extends AsArraySerializerBase<Object>

This is an optimized serializer for Lists that can be efficiently traversed by index (as opposed to others, such as LinkedList that cannot}.

Method Summary

Modifier and Type	Method	Description
protected StdContainerSerializer<?>	_withValueTypeSerializer(TypeSerializer vts)	Method that needs to be implemented to allow construction of a new serializer object with given TypeSerializer, used when addition type information is to be embedded.
boolean	hasSingleElement(Object value)	Method called to determine if the given value (of type handled by this serializer) contains exactly one element.
boolean	isEmpty(SerializationContext prov, Object value)	Method called to check whether given serializable value is considered "empty" value (for purposes of suppressing serialization of empty values).
final void	serialize(Object value0, tools.jackson.core.JsonGenerator g, SerializationContext ctxt)	Method that can be called to ask implementation to serialize values of type this serializer handles.

IndexedListSerializer	withResolved(BeanProperty property, TypeSerializer vts, ValueSerializer<?> elementSerializer, Boolean unwrapSingle, Object suppressableValue, boolean suppressNulls)	Factory method to use for creating differently configured instances, called by this class (from #createContextual), overridden by implementation class.

Method Details

_withValueTypeSerializer

protected StdContainerSerializer<?> _withValueTypeSerializer(TypeSerializer vts)

Description copied from class: StdContainerSerializer

Method that needs to be implemented to allow construction of a new serializer object with given TypeSerializer, used when addition type information is to be embedded.

Specified by:

_withValueTypeSerializer in class StdContainerSerializer<Object>

withResolved

public IndexedListSerializer withResolved(BeanProperty property,
 TypeSerializer vts,
 ValueSerializer<?> elementSerializer,
 Boolean unwrapSingle,
 Object suppressableValue,
 boolean suppressNulls)

Description copied from class: AsArraySerializerBase

Factory method to use for creating differently configured instances, called by this class (from #createContextual), overridden by implementation class.

NOTE: only implemented for backwards-compatibility with 3.0 version JacksonModules, otherwise would be abstract: sub-classes really need to override.

Overrides:

withResolved in class AsArraySerializerBase<Object>

isEmpty

public boolean isEmpty(SerializationContext prov,
 Object value)

Description copied from class: ValueSerializer

Method called to check whether given serializable value is considered "empty" value (for purposes of suppressing serialization of empty values).

Default implementation will consider only null values to be empty.

Specified by:

isEmpty in class StdContainerSerializer<Object>

hasSingleElement

public boolean hasSingleElement(Object value)

Description copied from class: StdContainerSerializer

Method called to determine if the given value (of type handled by this serializer) contains exactly one element.

Note: although it might seem sensible to instead define something like "getElementCount()" method, this would not work well for containers that do not keep track of size (like linked lists may not).

Note, too, that this method is only called by serializer itself; and specifically is not used for non-array/collection types like Map or Map.Entry instances.

Specified by:

hasSingleElement in class StdContainerSerializer<Object>

serialize

public final void serialize(Object value0,
 tools.jackson.core.JsonGenerator g,
 SerializationContext ctxt)
                     throws tools.jackson.core.JacksonException

Description copied from class: ValueSerializer

Method that can be called to ask implementation to serialize values of type this serializer handles.

Specified by:

serialize in class StdSerializer<Object>

Parameters:

value0 - Value to serialize; can not be null.

g - Generator used to output resulting Json content

ctxt - Context that can be used to get serializers for serializing Objects value contains, if any.

Throws:

tools.jackson.core.JacksonException

serializeContents

public void serializeContents(Object value0,
 tools.jackson.core.JsonGenerator g,
 SerializationContext ctxt)
                       throws tools.jackson.core.JacksonException

Specified by:

serializeContents in class AsArraySerializerBase<Object>

Throws:

tools.jackson.core.JacksonException

serializeContentsImpl

private void serializeContentsImpl(List<?> value,
 tools.jackson.core.JsonGenerator g,
 SerializationContext ctxt)
                            throws tools.jackson.core.JacksonException

Throws:

tools.jackson.core.JacksonException

serializeContentsUsingImpl

private void serializeContentsUsingImpl(List<?> value,
 tools.jackson.core.JsonGenerator g,
 SerializationContext ctxt,
 ValueSerializer<Object> ser)
                                 throws tools.jackson.core.JacksonException

Throws:

tools.jackson.core.JacksonException

serializeTypedContentsImpl

private void serializeTypedContentsImpl(List<?> value,
 tools.jackson.core.JsonGenerator g,
 SerializationContext ctxt)
                                 throws tools.jackson.core.JacksonException

Throws:

tools.jackson.core.JacksonException
