Method Detail

serialize

public void serialize(JsonWriter writer,
                      T value,
                      JsonSerializationContext ctx)
               throws JsonSerializationException

Serializes an object into JSON output.

Parameters:

writer - JsonWriter used to write the serialized JSON

value - Object to serialize

ctx - Context for the full serialization process

Throws:

JsonSerializationException - if an error occurs during the serialization

public void serialize(JsonWriter writer,
                      T value,
                      JsonSerializationContext ctx,
                      JsonSerializerParameters params)
               throws JsonSerializationException

Serializes an object into JSON output.

Parameters:

writer - JsonWriter used to write the serialized JSON

value - Object to serialize

ctx - Context for the full serialization process

params - Parameters for this serialization

Throws:

JsonSerializationException - if an error occurs during the serialization

serialize

public void serialize(JsonWriter writer,
                      T value,
                      JsonSerializationContext ctx,
                      JsonSerializerParameters params,
                      boolean isMapValue)
               throws JsonSerializationException

Serializes an object into JSON output.

Parameters:

writer - JsonWriter used to write the serialized JSON

value - Object to serialize

ctx - Context for the full serialization process

params - Parameters for this serialization

isMapValue - indicate if you're serializing a Map value

Throws:

JsonSerializationException - if an error occurs during the serialization

serializeNullValue

protected void serializeNullValue(JsonWriter writer,
                                  JsonSerializationContext ctx,
                                  JsonSerializerParameters params)

true if the value corresponds to the default one

isEmpty

protected boolean isEmpty(T value)

Parameters:

value - the value

Returns:

true if the value is empty

isAbsent

protected boolean isAbsent(T value)

Parameters:

value - the value

Returns:

true if the value is absent
