Method Summary

Modifier and Type	Method	Description
void	acceptJsonFormatVisitor(JsonFormatVisitorWrapper visitor, JavaType typeHint)	Default implementation specifies no format.
JsonSerializer<?>	createContextual(SerializerProvider serializers, BeanProperty property)	Method called to see if a different (or differently configured) serializer is needed to serialize values of specified property.
void	serialize(Object value, com.fasterxml.jackson.core.JsonGenerator g, SerializerProvider provider)	Method that can be called to ask implementation to serialize values of type this serializer handles.
final void	serializeWithType(Object value, com.fasterxml.jackson.core.JsonGenerator g, SerializerProvider provider, TypeSerializer typeSer)	Default implementation will write type prefix, call regular serialization method (since assumption is that value itself does not need JSON Array or Object start/end markers), and then write type suffix.

Method Details

serialize

public void serialize(Object value,
 com.fasterxml.jackson.core.JsonGenerator g,
 SerializerProvider provider)
               throws 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 class StdSerializer<Object>

Parameters:

value - Value to serialize; can not be null.

g - 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

serializeWithType

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

Description copied from class: StdScalarSerializer

Default implementation will write type prefix, call regular serialization method (since assumption is that value itself does not need JSON Array or Object start/end markers), and then write type suffix. This should work for most cases; some sub-classes may want to change this behavior.

Overrides:

serializeWithType in class StdScalarSerializer<Object>

Parameters:

value - Value to serialize; can not be null.

g - 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

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 StdScalarSerializer<Object>

Parameters:

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

Throws:

JsonMappingException

createContextual

public JsonSerializer<?> createContextual(SerializerProvider serializers,
 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 interface ContextualSerializer

Parameters:

serializers - Serializer provider to use for accessing config, other serializers

property - 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
