Method Detail

serialize
public void serialize(Object value, com.fasterxml.jackson.core.JsonGenerator gen, SerializerProvider provider) throws IOException
Description copied from class:JsonSerializerMethod that can be called to ask implementation to serialize values of type this serializer handles.- Specified by:
serializein classStdSerializer<Object>- Parameters:
value- Value to serialize; can not be null.gen- Generator used to output resulting Json contentprovider- Provider that can be used to get serializers for serializing Objects value contains, if any.- Throws:
IOException
-
serializeWithType
public final void serializeWithType(Object value, com.fasterxml.jackson.core.JsonGenerator gen, SerializerProvider provider, TypeSerializer typeSer) throws IOException
Description copied from class:JsonSerializerMethod 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
UnsupportedOperationExceptionto 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, asSTART-ARRAY/END-ARRAYandSTART-OBJECT/END-OBJECTpairs need to be properly handled with respect to serializing of contents.- Overrides:
serializeWithTypein classJsonSerializer<Object>- Parameters:
value- Value to serialize; can not be null.gen- Generator used to output resulting Json contentprovider- 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
-
isEmpty
public boolean isEmpty(SerializerProvider provider, Object value)
Description copied from class:JsonSerializerMethod 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.
NOTE: replaces
JsonSerializer.isEmpty(Object), which was deprecated in 2.5- Overrides:
isEmptyin classJsonSerializer<Object>
-
getSchema
public JsonNode getSchema(SerializerProvider provider, Type typeHint) throws JsonMappingException
Description copied from class:StdSerializerDefault implementation simply claims type is "string"; usually overriden by custom serializers.- Specified by:
getSchemain interfaceSchemaAware- Overrides:
getSchemain classStdSerializer<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:StdSerializerDefault implementation specifies no format. This behavior is usually overriden by custom serializers.- Specified by:
acceptJsonFormatVisitorin interfaceJsonFormatVisitable- Overrides:
acceptJsonFormatVisitorin classStdSerializer<Object>typeHint- Type of element (entity like property) being visited- Throws:
JsonMappingException
-
failForEmpty
protected void failForEmpty(SerializerProvider prov, Object value) throws JsonMappingException
- Throws:
JsonMappingException
