serialize
public void serialize(java.lang.Object value, JsonGenerator g, 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 classJsonSerializer<java.lang.Object>
- Parameters:
value
- Value to serialize; can not be null.g
- 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 value, JsonGenerator g, 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:
value
- Value to serialize; can not be null.g
- 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
-
handledType
public java.lang.Class<java.lang.Object> handledType()
Description copied from class:JsonSerializer
Method for accessing type of Objects this serializer can handle. Note that this information is not guaranteed to be exact -- it may be a more generic (super-type) -- but it should not be incorrect (return a non-related type).Default implementation will return null, which essentially means same as returning
Object.class
would; that is, that nothing is known about handled type.- Overrides:
handledType
in classJsonSerializer<java.lang.Object>
-
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
