Package org.eclipse.yasson.internal.serializer

Class MapDeserializer<T extends Map<?,?>>

java.lang.Object

org.eclipse.yasson.internal.serializer.AbstractItem<T>

org.eclipse.yasson.internal.serializer.AbstractContainerDeserializer<T>

org.eclipse.yasson.internal.serializer.MapDeserializer<T>

Type Parameters:

T - map type

All Implemented Interfaces:

javax.json.bind.serializer.JsonbDeserializer<T>, RuntimeTypeInfo, CurrentItem<T>, EmbeddedItem

public class MapDeserializer<T extends Map<?,?>>
extends AbstractContainerDeserializer<T>
implements EmbeddedItem

Item implementation for Map fields. According to JSON specification object can have only string keys. Nevertheless the implementation lets the key be a basic object that was serialized into a string representation. Therefore the key is also parsed to convert it into its parametrized type.

Constructor Details

MapDeserializer

protected MapDeserializer(DeserializerBuilder builder)

Create instance of current item with its builder.

Parameters:

builder - DeserializerBuilder used to build this instance

Method Details

getInstance

public T getInstance(Unmarshaller unmarshaller)

Description copied from class: AbstractContainerDeserializer

Creates and initializes an instance of deserializing item.

Specified by:

getInstance in class AbstractContainerDeserializer<T extends Map<?,?>>

Parameters:

unmarshaller - Current deserialization context.

Returns:

An instance of deserializing item.

appendResult

public void appendResult(Object result,
 Unmarshaller context)

Description copied from class: AbstractContainerDeserializer

After object is transitively deserialized from JSON, "append" it to its wrapper. In case of a field set value to field, in case of collections or other embedded objects use methods provided.

Specified by:

appendResult in class AbstractContainerDeserializer<T extends Map<?,?>>

Parameters:

result - An instance result of an item.

context - Current unmarshalling context.

deserializeNext

protected void deserializeNext(javax.json.stream.JsonParser parser,
 Unmarshaller context)

Description copied from class: AbstractContainerDeserializer

Determine class mappings and create an instance of a new deserializer. Currently processed deserializer is pushed to stack, for waiting till new object is finished.

Specified by:

deserializeNext in class AbstractContainerDeserializer<T extends Map<?,?>>

Parameters:

parser - Json parser.

context - Current unmarshalling context.

moveToFirst

protected JsonbRiParser.LevelContext moveToFirst(JsonbParser parser)

Description copied from class: AbstractContainerDeserializer

Move to first event for current deserializer structure.

Specified by:

moveToFirst in class AbstractContainerDeserializer<T extends Map<?,?>>

Parameters:

parser - Json parser.

Returns:

First event.
