public abstract class BeanSerializerBase extends StdSerializer<java.lang.Object> implements ContextualSerializer, ResolvableSerializer, JsonFormatVisitable, SchemaAware
Base class both for the standard bean serializer, and couple of variants that only differ in small details. Can be used for custom bean serializers as well, although that is not the primary design goal.- See Also:

resolve
public void resolve(SerializerProvider provider) throws JsonMappingException
We need to implementResolvableSerializer
to be able to properly handle cyclic type references.- Specified by:
resolve
in interfaceResolvableSerializer
- Parameters:
provider
- Provider that has constructed serializer this method is called on.- Throws:
JsonMappingException
-
findConvertingSerializer
protected JsonSerializer<java.lang.Object> findConvertingSerializer(SerializerProvider provider, BeanPropertyWriter prop) throws JsonMappingException

JsonMappingException
- Since:

-
createContextual
public JsonSerializer<?> createContextual(SerializerProvider provider, BeanProperty property) throws JsonMappingException
Description copied from interface:ContextualSerializer
Method called to see if a different (or differently configured) serializer is needed to serialize values of specified property. Note that instance that this method is called on is typically shared one and as a result method should NOT modify this instance but rather construct and return a new instance. This instance should only be returned as-is, in case it is already suitable for use.- Specified by:
createContextual
in interfaceContextualSerializer
- Parameters:
provider
- Serializer provider to use for accessing config, other serializersproperty
- Method or field that represents the property (and is used to access value to serialize). Should be available; but there may be cases where caller cannot provide it and null is passed instead (in which case impls usually pass 'this' serializer as is)- Returns:
- Serializer to use for serializing values of specified property; may be this instance or a new instance.
- Throws:
JsonMappingException
-
properties
public java.util.Iterator<PropertyWriter> properties()
Description copied from class:JsonSerializer
Accessor for iterating over logical properties that the type handled by this serializer has, from serialization perspective. Actual type of properties, if any, will beBeanPropertyWriter
. Of standard Jackson serializers, onlyBeanSerializer
exposes properties.- Overrides:
properties
in classJsonSerializer<java.lang.Object>
-
usesObjectId
public boolean usesObjectId()
Description copied from class:JsonSerializer
Method that can be called to see whether this serializer instance will use Object Id to handle cyclic references.- Overrides:
usesObjectId
in classJsonSerializer<java.lang.Object>
-
serialize
public abstract void serialize(java.lang.Object bean, com.fasterxml.jackson.core.JsonGenerator gen, SerializerProvider provider) 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.- Specified by:
serialize
in classStdSerializer<java.lang.Object>
- 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 classJsonSerializer<java.lang.Object>
- Parameters:
bean
- Value to serialize; can not be null.gen
- Generator used to output resulting Json contentprovider
