Method Detail

serialize

public void serialize(Object value,
             com.fasterxml.jackson.core.JsonGenerator jgen,
             SerializerProvider provider)
               throws IOException,
                      JsonMappingException

Description copied from class: JsonSerializer

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

Specified by:

serialize in class StdSerializer<Object>

Parameters:

value - Value to serialize; can not be null.

jgen - Generator used to output resulting Json content

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

Throws:

IOException

JsonMappingException

serializeWithType

public final void serializeWithType(Object value,
                     com.fasterxml.jackson.core.JsonGenerator jgen,
                     SerializerProvider provider,
                     TypeSerializer typeSer)
                             throws IOException,
                                    com.fasterxml.jackson.core.JsonGenerationException

Description copied from class: JsonSerializer

Method that can be called to ask implementation to serialize values of type this serializer handles, using specified type serializer for embedding necessary type information.

Default implementation will throw UnsupportedOperationException to indicate that proper type handling needs to be implemented.

For simple datatypes written as a single scalar value (JSON String, Number, Boolean), implementation would look like:

  // note: method to call depends on whether this type is serialized as JSON scalar, object or Array!
  typeSer.writeTypePrefixForScalar(value, gen);
  serialize(value, gen, provider);
  typeSer.writeTypeSuffixForScalar(value, gen);

and implementations for type serialized as JSON Arrays or Objects would differ slightly, as START-ARRAY>/END-ARRAY and START-OBJECT>/END-OBJECT pairs need to be properly handled with respect to serializing of contents.

Overrides:

serializeWithType in class JsonSerializer<Object>

Parameters:

value - Value to serialize; can not be null.

jgen - Generator used to output resulting Json content

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

typeSer - Type serializer to use for including type information

Throws:

IOException

com.fasterxml.jackson.core.JsonGenerationException

getSchema

public JsonNode getSchema(SerializerProvider provider,
                 Type typeHint)
                   throws JsonMappingException

Description copied from class: StdSerializer

Default implementation simply claims type is "string"; usually overriden by custom serializers.

Specified by:

getSchema in interface SchemaAware

Overrides:

getSchema in class StdSerializer<Object>

Parameters:

provider - The serializer provider.

typeHint - A hint about the type.

Returns:

Json-schema for this serializer.

Throws:

JsonMappingException

acceptJsonFormatVisitor

public void acceptJsonFormatVisitor(JsonFormatVisitorWrapper visitor,
                           JavaType typeHint)
                             throws JsonMappingException

Description copied from class: StdSerializer

Default implementation specifies no format. This behavior is usually overriden by custom serializers.

Specified by:

acceptJsonFormatVisitor in interface JsonFormatVisitable

Overrides:

acceptJsonFormatVisitor in class StdSerializer<Object>

typeHint - Type of element (entity like property) being visited

Throws:

JsonMappingException

failForEmpty

protected void failForEmpty(Object value)
                     throws JsonMappingException

Throws:

JsonMappingException
