Constructor Details

MapSerializer

protected MapSerializer(SerializerBuilder builder)

Creates an instance of Map serialization.

Parameters:

builder - current instance of SerializerBuilder

Method Details

beforeSerialize

protected void beforeSerialize(Map<K,V> obj)

Check Map before serialization. Decide whether provided Map can be serialized as JsonObject or as JsonArray of map entries.

Overrides:

beforeSerialize in class AbstractContainerSerializer<Map<K,V>>

Parameters:

obj - Map to be serialized

serializeInternal

protected void serializeInternal(Map<K,V> obj,
 javax.json.stream.JsonGenerator generator,
 javax.json.bind.serializer.SerializationContext ctx)

Serialize content of provided Map. Passing execution to delegate instance.

Specified by:

serializeInternal in class AbstractContainerSerializer<Map<K,V>>

Parameters:

obj - Map to be serialized

generator - JSON format generator

ctx - JSON serialization context

writeStart

protected void writeStart(javax.json.stream.JsonGenerator generator)

Write start of Map serialization. Passing execution to delegate instance.

Specified by:

writeStart in class AbstractContainerSerializer<Map<K,V>>

Parameters:

generator - JSON format generator

writeStart

protected void writeStart(String key,
 javax.json.stream.JsonGenerator generator)

Write start of Map serialization. Passing execution to delegate instance.

Specified by:

writeStart in class AbstractContainerSerializer<Map<K,V>>

Parameters:

key - JSON key name

generator - JSON format generator

writeEnd

protected void writeEnd(javax.json.stream.JsonGenerator generator)

Write end of Map serialization. Passing execution to delegate instance.

Overrides:

writeEnd in class AbstractContainerSerializer<Map<K,V>>

Parameters:

generator - JSON format generator

isNullable

protected boolean isNullable()

Return an information whether to serialize null values too.

Returns:

null values shall be serialized too when true

serializeKey

protected void serializeKey()

Flag to serialize the key in the map.

serializeValue

protected void serializeValue()

Flag to serialize the value in the map.

getValueType

protected Type getValueType(Type valueType)

In a map the type can refer to the key or the value type depending which one is currently being processed. The field actualTypeArgument controls which one is being serialized at the moment.

Overrides:

getValueType in class AbstractContainerSerializer<Map<K,V>>

Parameters:

valueType - The value type which should be of type Map<K,V>

Returns:

The type for the key or the value
