Class MapProperty

java.lang.Object

com.fasterxml.jackson.databind.ser.PropertyWriter

com.fasterxml.jackson.databind.ser.std.MapProperty

public class MapProperty
extends PropertyWriter

Helper class needed to support flexible filtering of Map properties with generic JSON Filter functionality. Since Maps are not handled as a collection of properties by Jackson (unlike POJOs), bit more wrapping is required.

void	reset(Object key, Object value, JsonSerializer<Object> keySer, JsonSerializer<Object> valueSer) Initialization method that needs to be called before passing property to filter.
void	serializeAsElement(Object pojo, JsonGenerator jgen, SerializerProvider provider) Serialization method called when output is to be done as an array, that is, not using property names.
void	serializeAsField(Object pojo, JsonGenerator jgen, SerializerProvider provider) The main serialization method called by filter when property is to be written normally.
void	serializeAsOmittedField(Object pojo, JsonGenerator jgen, SerializerProvider provider) Serialization method that filter needs to call in cases where property is to be filtered, but the underlying data format requires a placeholder of some kind.
void	serializeAsPlaceholder(Object pojo, JsonGenerator jgen, SerializerProvider provider) Serialization method called when doing tabular (positional) output from databind, but then value is to be omitted.

Method Detail

reset

public void reset(Object key,
         Object value,
         JsonSerializer<Object> keySer,
         JsonSerializer<Object> valueSer)

Initialization method that needs to be called before passing property to filter.

getName

public String getName()

Specified by:

getName in class PropertyWriter

getFullName

public PropertyName getFullName()

Specified by:

getFullName in class PropertyWriter

serializeAsField

public void serializeAsField(Object pojo,
                    JsonGenerator jgen,
                    SerializerProvider provider)
                      throws IOException

Description copied from class: PropertyWriter

The main serialization method called by filter when property is to be written normally.

Specified by:

serializeAsField in class PropertyWriter

Throws:

IOException

serializeAsOmittedField

public void serializeAsOmittedField(Object pojo,
                           JsonGenerator jgen,
                           SerializerProvider provider)
                             throws Exception

Description copied from class: PropertyWriter

Serialization method that filter needs to call in cases where property is to be filtered, but the underlying data format requires a placeholder of some kind. This is usually the case for tabular (positional) data formats such as CSV.

Specified by:

serializeAsOmittedField in class PropertyWriter

Throws:

Exception

serializeAsElement

public void serializeAsElement(Object pojo,
                      JsonGenerator jgen,
                      SerializerProvider provider)
                        throws Exception

Description copied from class: PropertyWriter

Serialization method called when output is to be done as an array, that is, not using property names. This is needed when serializing container (Collection, array) types, or POJOs using tabular ("as array") output format.

Note that this mode of operation is independent of underlying data format; so it is typically NOT called for fully tabular formats such as CSV, where logical output is still as form of POJOs.

Specified by:

serializeAsElement in class PropertyWriter

Throws:

Exception

serializeAsPlaceholder

public void serializeAsPlaceholder(Object pojo,
                          JsonGenerator jgen,
                          SerializerProvider provider)
                            throws Exception

Description copied from class: PropertyWriter

Serialization method called when doing tabular (positional) output from databind, but then value is to be omitted. This requires output of a placeholder value of some sort; often similar to PropertyWriter.serializeAsOmittedField(java.lang.Object, com.fasterxml.jackson.core.JsonGenerator, com.fasterxml.jackson.databind.SerializerProvider).

Specified by:

serializeAsPlaceholder in class PropertyWriter

Throws:

Exception

depositSchemaProperty

public void depositSchemaProperty(JsonObjectFormatVisitor objectVisitor)
                           throws JsonMappingException

Description copied from class: PropertyWriter

Traversal method used for things like JSON Schema generation, or POJO introspection.

Specified by:

depositSchemaProperty in class PropertyWriter

Throws:

JsonMappingException

depositSchemaProperty

@Deprecated
public void depositSchemaProperty(ObjectNode propertiesNode,
                                    SerializerProvider provider)
                           throws JsonMappingException

Deprecated.

Description copied from class: PropertyWriter

Legacy method called for JSON Schema generation; should not be called by new code

Specified by:
