com.fasterxml.jackson.databind.JsonSerializer<T>

com.fasterxml.jackson.databind.ser.std.StdSerializer<T>

com.fasterxml.jackson.databind.ser.std.StringSerializer

All Implemented Interfaces:

JsonFormatVisitable, SchemaAware, Serializable

public final class StringSerializer
extends NonTypedScalarSerializerBase<Object>

This is the special serializer for regular Strings.

Since this is one of "native" types, no type information is ever included on serialization (unlike for most scalar types as of 1.5)

Method Summary

Modifier and Type	Method and Description
void	acceptJsonFormatVisitor(JsonFormatVisitorWrapper visitor, JavaType typeHint) Default implementation specifies no format.
JsonNode	getSchema(SerializerProvider provider, Type typeHint) Default implementation simply claims type is "string"; usually overriden by custom serializers.
boolean	isEmpty(Object value) Deprecated.
boolean	isEmpty(SerializerProvider prov, Object value) Method called to check whether given serializable value is considered "empty" value (for purposes of suppressing serialization of empty values).
void	serialize(Object value, com.fasterxml.jackson.core.JsonGenerator jgen, SerializerProvider provider) Method that can be called to ask implementation to serialize values of type this serializer handles.

Method Detail

isEmpty

@Deprecated
public boolean isEmpty(Object value)

Deprecated.

For Strings, both null and Empty String qualify for emptiness.

Overrides:

isEmpty in class JsonSerializer<Object>

isEmpty

public boolean isEmpty(SerializerProvider prov,
                       Object value)

Description copied from class: JsonSerializer

Method 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), deprecated in 2.5

Overrides:

isEmpty in class JsonSerializer<Object>

serialize

public void serialize(Object value,
                      com.fasterxml.jackson.core.JsonGenerator jgen,
                      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.

jgen - 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

getSchema

public JsonNode getSchema(SerializerProvider provider,
                          Type typeHint)

Description copied from class: StdSerializer

Default implementation simply claims type is "string"; usually overriden by custom serializers.

Specified by:

getSchema in interface SchemaAware

Overrides:

getSchema in class StdScalarSerializer<Object>

Parameters:

provider - The serializer provider.

typeHint - A hint about the type.

Returns:

Json-schema for this serializer.

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>

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

Throws:

JsonMappingException
