Class IndexedListSerializer

java.lang.Object
  com.fasterxml.jackson.databind.JsonSerializer<T>
      com.fasterxml.jackson.databind.ser.std.StdSerializer<T>
          com.fasterxml.jackson.databind.ser.ContainerSerializer<T>

                  com.fasterxml.jackson.databind.ser.impl.IndexedListSerializer

All Implemented Interfaces:

SchemaAware, ContextualSerializer

public final class IndexedListSerializer
extends AsArraySerializerBase<List<?>>

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

IndexedListSerializer

public IndexedListSerializer(JavaType elemType,
                             boolean staticTyping,
                             TypeSerializer vts,

IndexedListSerializer

public IndexedListSerializer(IndexedListSerializer src,
                             BeanProperty property,
                             TypeSerializer vts,
                             JsonSerializer<?> valueSerializer)

Method Detail

withResolved

public IndexedListSerializer withResolved(BeanProperty property,
                                          TypeSerializer vts,
                                          JsonSerializer<?> elementSerializer)

Specified by:

withResolved in class AsArraySerializerBase<List<?>>

isEmpty

public boolean isEmpty(List<?> value)

Description copied from class: JsonSerializer

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 ContainerSerializer<List<?>>

hasSingleElement

public boolean hasSingleElement(List<?> value)

Description copied from class: ContainerSerializer

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).

Specified by:

hasSingleElement in class ContainerSerializer<List<?>>

_withValueTypeSerializer

public ContainerSerializer<?> _withValueTypeSerializer(TypeSerializer vts)

Description copied from class: ContainerSerializer

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 ContainerSerializer<List<?>>

serializeContents

public void serializeContents(List<?> value,
                              com.fasterxml.jackson.core.JsonGenerator jgen,

                              com.fasterxml.jackson.core.JsonGenerationException
