unwrappingSerializer
public JsonSerializer<java.lang.Object> unwrappingSerializer(NameTransformer transformer)
Description copied from class:JsonSerializer
Method that will return serializer instance that produces "unwrapped" serialization, if applicable for type being serialized (which is the case for some serializers that produce JSON Objects as output). If no unwrapped serializer can be constructed, will simply return serializer as-is.Default implementation just returns serializer as-is, indicating that no unwrapped variant exists
- Overrides:
unwrappingSerializer
in classJsonSerializer<java.lang.Object>
- Parameters:
transformer
- Name transformation to use to convert between names of unwrapper properties
-
isUnwrappingSerializer
public boolean isUnwrappingSerializer()
Description copied from class:JsonSerializer
Accessor for checking whether this serializer is an "unwrapping" serializer; this is necessary to know since it may also require caller to suppress writing of the leading property name.- Overrides:
isUnwrappingSerializer
in classJsonSerializer<java.lang.Object>
-
withObjectIdWriter
public BeanSerializerBase withObjectIdWriter(ObjectIdWriter objectIdWriter)
Description copied from class:BeanSerializerBase
Mutant factory used for creating a new instance with differentObjectIdWriter
.- Specified by:
withObjectIdWriter
in classBeanSerializerBase
-
withFilterId
public BeanSerializerBase withFilterId(java.lang.Object filterId)
Description copied from class:BeanSerializerBase
Mutant factory used for creating a new instance with different filter id (used withJsonFilter
annotation)- Specified by:
withFilterId
in classBeanSerializerBase
-
withByNameInclusion
protected BeanSerializerBase withByNameInclusion(java.util.Set<java.lang.String> toIgnore, java.util.Set<java.lang.String> toInclude)
Description copied from class:BeanSerializerBase
Mutant factory used for creating a new instance with additional set of properties to ignore or include (from properties this instance otherwise has)- Specified by:
withByNameInclusion
in classBeanSerializerBase
-
withProperties
protected BeanSerializerBase withProperties(BeanPropertyWriter[] properties, BeanPropertyWriter[] filteredProperties)
Description copied from class:BeanSerializerBase
Mutant factory used for creating a new instance with modified set of properties.Note: in 2.11.x, need to keep non-abstract for slightly better compatibility (XML module extends)
- Specified by:
withProperties
in classBeanSerializerBase
-
asArraySerializer
protected BeanSerializerBase asArraySerializer()
JSON Array output cannot be done if unwrapping operation is requested; so implementation will simply return 'this'.- Specified by:
asArraySerializer
in classBeanSerializerBase
-
serialize
public final void serialize(java.lang.Object bean, com.fasterxml.jackson.core.JsonGenerator gen, SerializerProvider provider) throws java.io.IOException
Main serialization method that will delegate actual output to configuredBeanPropertyWriter
instances.- Specified by:
serialize
in classBeanSerializerBase
- Parameters:
bean
- 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:
java.io.IOException
-
serializeWithType
public void serializeWithType(java.lang.Object bean, com.fasterxml.jackson.core.JsonGenerator gen, SerializerProvider provider, TypeSerializer typeSer) throws java.io.IOException
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, asSTART-ARRAY
/END-ARRAY
andSTART-OBJECT
/END-OBJECT
pairs need to be properly handled with respect to serializing of contents.- Overrides:
serializeWithType
in classBeanSerializerBase
- Parameters:
bean
- 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:
java.io.IOException
-
